Qualitative data benefits from a set of easily distinguishable colors. (I’ll also reiterate Reto Stöckli’s invaluable work building the land and cloud textures, which were the hard parts.). False-color images, which incorporate wavelengths of light invisible to humans, can reveal fascinating information—but they’re often misleading to people without formal training in remote sensing. Palettes aren’t the only important decision when visualizing data with color: you also need to consider scaling. But what separates “adequate” from “good” from “great” isn’t a matter of following rules—it’s a matter of aesthetics and judgement. Eduard Imhof’s Cartographic Relief Presentation explains the theory and meticulous craft applied to Swiss topographic maps (zoom in). ... Just as with Paddy, I divided Rob’s game into ten-minute chukkas. The combination of two or more datasets often tell a story better than a single dataset, and the best visualizations tell stories. To ensure your designs are accessible, choose from the color blind safe palettes on Color Brewer, or one of the online color blindness simulators. Finally: Thanks to the NASA family, and to all of you who’ve expressed appreciation for my pictures over the years. So far so good. In essence, there’s a qualitative change in the data (often a change in sign) as it crosses a threshold. NASA's famous "Blue Marble" image. (I know I harp on the rainbow palette, and I’m sure you’re tired of it, but despite the well known flaws it’s still used in a disproportionate amount of visualization.) When I applied the same color scale to a single day’s data, however, I was surprised to see that the coolest areas (irrigated fields) were subjectively hotter than their surroundings. (Map based on Microwave OI SST Data from Remote Sensing Systems.). The lower image ranges from 0˚ to 28˚ Celsius, eliminating details in areas with very low or very high temperatures. In the curves adjustment layer, click near the center of the line that runs at a 45˚ angle from lower left to upper right. Click the image to enlarge. Itten’s text focuses on color theory (including a somewhat outdated explanation of the physiology of color perception) and the mixture of pigments. The Ames tool provides more flexibility than Color Brewer, but is also limited in the available range of colors. The widely-used Red-Blue divergent palette on Color Brewer. Unfortunately, Photoshop has no native GeoTIFF support—anytime you re-save a GeoTIFF, the metadata disappears. Part 2: The “Perfect” Palette If we want to tell more complex stories, we have to use different techniques.". In the end, the true test of the value of a color scale is simply ‘Does it work?’”, Bernice Rogowitz and Lloyd Treinish authored two key papers in the 1990s: How NOT to Lie with Visualization and Why Should Engineers and Scientists Be Worried About Color? Despite our best intentions, the Earth Observatory long used a vegetation anomaly palette that was completely unreadable by color blind viewers. The first step is to select the white eyedropper (the bottom of the three eyedropper icons on the left edge of the Levels Palette), and find an area of the brightest area of the image that we know is white: a puffy cloud, or even better, pristine snow. Information Visualization is more thorough, Visual Thinking for Design is more concise. The essential news for energy & environment professionals, © Politico, LLC   As far as I know, these tools are the state of the art. After white balancing, the histograms of the red, green, and blue channels in the Mount Shasta image look like this: Notice that the value of white in each channel is slightly different (213, 202, and 201), and that there’s a small number of pixels above the white point in each channel. Robert has 8 jobs listed on their profile. It describes Patterson’s technique of using two color palettes to denote elevation on a single map: one optimized for arid areas, the other for humid ones. But aerial photographs from great heights, even in color, are often quite misleading, the Earth’s surface relief usually appearing too flat and the vegetation mosaic either full of contrasts and everchanging complexities, or else veiled in a gray-blue haze. Figure out why it works, and incorporate those elements into your own projects. Slight differences in the characteristics of the different color bands, combined with scattering of blue light by the atmosphere, can add an overall tint to the image. Non-diverging Breakpoints By using palettes with different hues but an identical range of lightness and saturation, they are directly comparable but remain distinct from one another. When wildfires in Siberia made the news recently, for example, Jesse Allen, a member of Simmon's visualization team, made two images using data from the MODIS satellite (ClimateWire, Aug. 12). You can leave a comment here or at visual.ly), Naomi B. Robbins demonstrated that the standard land cover classification palette fails for color-deficient viewers. I consider those the fundamentals of color for data visualization. Part 2: The “Perfect” Palette Palettes defined in a perceptual color space—particularly CIE L*C*h—will be more accurate than those composed using RGB or HSV color spaces, which are more suited to computers than people. Qualitative data (occasionally known as categorical or thematic data) is distinct from sequential and divergent data: instead of representing proportional relationships, color is used to separate areas into distinct categories. Using a yellow-red palette, cool irrigated fields appear warmer than the nearby dunes, inverting the true relationship. “@lefsky @NASAPersevere And an entire generation of Mars-conspiracy theorists will think the sky on Mars is blue… Don’t underestimate “what a human would see.” *Analyze* your data how you need to. The previous posts are my personal take on using color in visualization. I’m indebted to them. We think of shadows as black, however, so I think it’s best to remove most of the influence of scattered light (a little bit of the atmospheric influence was already removed by choosing a white point) by adjusting the black points in each channel. It may just be that I’m enamored with Alberto Cairo, but I’m growing increasingly fond of slope graphs. In addition to the online color-calculator, they offer libraries to convert from one color space to another. He told Quartz it’s not a photograph, but a sophisticated visualization. Google Earth's New Timelapse Feature Lets You See How Our Planet Has Changed In Four Decades. Charlie Loyd, a satellite imagery specialist at MapBox, a Washington, D.C.-based company that makes custom Web maps, said he had long admired the work coming out of the Earth Observatory, and one day realized that the visualizations he liked the most came from one person -- Simmon. They occasionally tell stories more clearly than more conventional graph types. Encoding quantitative data with color is (sometimes literally) a simple matter of paint-by-numbers. A view of Earth from the ISS on September 2, 2014 (presumably Photoshopped by evil NWO governments). A logarithmic base-10 scale reveals complex structures throughout the oceans, in both coastal and deep water. A gradient map allows you to set an arbitrary number of color points to blend between, and change both the relative spacing (in increments of one percent) and relative weighting of each point. The first step, of course, is to download some data. D3.js allows both the selection of start and end points and interpolation in perceptual color spaces. Each of these scenes covers an area of about 185 by 185 kilometers (115 by 115 miles)—34,200 square km (13,200 square miles)—for a total of 13,690,000 square km (5,290,000 square miles) per day. We need 9 colors because there are 8 divisions between each specified color, which divides evenly into the 256 available indices. Artists (particularly painters) have long been concerned, possibly better described as obsessed, with color. Generate continuous as well as discrete palettes, exported as an indexed color image or color table. This post was originally published by the Society for News Design for the Malofiej Infographic World Summit. What makes it so powerful is that he incorporates four independent temperature data sets, said Loyd. Pale yellow to deep red felt like an obvious choice. Of course the data is in Watts per square meter per steradian, and the useful range is something around 0.0000000005 to 0.0000000500. He also included a way to pick intermediate hues, which adds some welcome flexibility to palette-building. To build an indexed palette (also called a color look-up table), start with one of the 9-color Color Brewer palettes. This type of palette works because it takes advantage of pre attentive processing: our visual systems can discriminate the different colors quickly and without conscious thought. Very little (if any at all) of the Earth’s surface is truly black. The NASA Ames color tool, Lch color gradient picker, and Online Color Converter are more-or-less useful for building sequential or divergent scales. Then convert the grayscale image to a color one by selecting Image > Mode > RGB Color. even Edward Tufte @EdwardTufte. Part 6: References and Resources for Visualization Professionals, Shaded Relief: Ideas and Techniques about Relief Presentation on Maps, The Development and Rationale of Cross-blended Hypsometric Tints, Rainbow Color Map (Still) Considered Harmful. Phew. Pretty much any dataset can be categorized as one of three types—sequential, divergent, and qualitative—each suited to a different color scheme. Bronze Seen from above, the Earth’s surface is made brighter and bluer by the atmosphere (compare the hue of the clouds to the hue of the panels on the International Space Station). Setting the white point does two things: the brightest handful of pixels in the image are now as light as possible, and the scene is partially white balanced. Until further notice, the University of Arizona, in accordance with the guidelines recommended by the Centers for Disease Control and Prevention encourages all employees to work remotely. A satellite in a geostationary orbit is in a “sweet spot” in which it orbits at the same speed that Earth rotates. Here’s the latest collection from September 2013. Four urban densities are shown in shades of red, 3 forest types in shades of green, and different types of cropland in yellow and brown. Two graphic variations done by Simmon on the theme of rising global temperatures; one is a version of the celebrated "hockey stick" graph made famous by former Vice President Al Gore. Sequential data lies along a smooth continuum, and is suited to a palette with a linear change in lightness, augmented by simultaneous shifts in hue and saturation. This may help patterns remain visible over the entire range of data. And any scaling that showed faint details left cities completely blown out. Everyone should definitely read Rob Simmon’s six-part “Subtleties of Color” article, written when Rob worked for NASA. In addition to sequential, Cynthia Brewer defines two additional types of data: divergent and qualitative. The next step is to brighten the entire image (at least brighten it enough to make further adjustments). Check out the quilted thumbnails of Google image search results for words like “clean” (mint green) “malevolent” (ochre) and “abstract” (blue). Different Data, Different Colors Areas of no data are almost always less important than valid data points, but it’s still essential to include them in a visualization. How do the colors used for the data interact with labels? Notice to California Residents   The federal health-care exchange’s abysmal success rate (The Washington Post) What are the more subtle aspects of color for data visualization? For more information on this image, please visit NASA… In Photoshop, there’s two ways to do this: create a custom indexed color palette (good for 8-bit data, with a range of 256 values), or create a gradient map (useful for applying color to 16-bit datasets). In addition to color, consider the other aspects of design: typography, line, shape, alignment, etc. 7. Whenever possible, make intuitive palettes. (NASA images by Robert Simmon, using Landsat data/EarthObservatory) This is the bottom line. Finding things is the fun part. But in the graphic, those four sources, corroborating each other, make the case for a warming world even stronger. in neuroscience, pursued a Ph.D. at Northwestern University, and worked at NASA Ames. Matt Hall @kwinkunks Sign in to check out what your friends, family & interests have been capturing & sharing around the world. but a fair number of datasets lend themselves to particular colors. Charlie Loyd, of MapBox, has a pair of posts detailing Landsat 8’s bands, and a method for using open-source tools to make Landsat images. Image of the Day for March 4, 2018. I mentioned Color Mine in my previous post, on tools. All pictures of the globe earth are now... več Then I use curves to fine-tune the image, matching it to our nonlinear perception of light. Vegetation is green, barren ground is gray or beige. They change with the seasons and the time of day, with the weather, the direction of views, and with the distance from which they are observed, etc. My short bio: As part of a continuing celebration of Earth Science Week and this year's theme "Mapping Our World," Robert Simmon will answer questions about his role as a data visualizer and designer with NASA's Earth Observatory. If the data varies over a very wide range, consider a logarithmic scale. Here's his collection (updated after the original writing of this post): Priya Kumar's thoughts after Tapestry Conference Many of these bloggers are active on Twitter: Privacy Policy   LC80450292013225LGN00_B10.TIF . Changing from blue to yellow without going through green, for instance. I hope my perspective is useful, but it’s primarily a synthesis of the work of others. Alberto Cairo, a well-known design expert who has written a book on information graphics called "The Functional Art" and who teaches at the University of Miami, said the work that Simmon does at the Earth Observatory appeals to him because it is multimedia, using infographics, text and photographs to tell stories about the Earth. I do not usually recommend using a divergent palette to show sequential data, but this map cleverly uses the breakpoint (light yellow) to show median elevation. Be aware of how the various elements of your design fit together. "I want imagery that people not only think looks interesting, but that they learn something from," said Simmon. For 16-bit data (a digital elevation model, for example), use a gradient map. It varies perceptually in lightness and rotates around the hue circle one and a half times, contributing additional contrast. In addition to developing Color Brewer, Cynthia Brewer has written two books relevant to color and visualization. This map shows net primary productivity [a measure of the how much plants breathe (technically the amount of carbon plants take from the atmosphere and use to grow each year)] on land and in the ocean. It adds an offset to account for some spurious negative values; multiplies by a large constant to fit the data into the 65,536 values allowed in a 2-byte integer file; calculates the square root to improve contrast, sets any values above 65,535 to 65,535; then converts from floating point to unsigned integer. This could be misleading. The maximum lightness with any hue is 90, the darkest 10 (inevitably with very low saturation). Indeed, how can it be when there is no real consistency in the natural landscape, which offers endless variations of color? The two datasets are qualitatively different (phytoplankton growing in the ocean, terrestrial plants on land), but quantitatively the same. LC80450292013225LGN00_B2.TIF Follow good design practice as well as good visualization practice when developing imagery. I sometimes find it helpful to find photographs of a location to double-check my corrections, either with a generic image search or through a photography archive like flickr. Also, label each element directly. "Capturing people's attention with true color imagery is pretty easy," Simmon explained in a 2012 presentation he gave to attendees at the American Geophysical Union conference in San Francisco. To make the data more manageable, show detail in dark and bright areas, and allow export to Photoshop I did a quick band math calculation: UINT(SQRT((b1+1.5E-9)*4E15)*(SQRT((b1+1.5E-9)*4E15) lt 65535) + (SQRT((b1+1.5E-9)*4E15) ge 65535)*65535). Let me get this out of the way: this was the first NASA image of an entire hemisphere of the Earth made with full-color data since the Apollo 17 crew returned from the Moon. Part 3: Different Data, Different Colors It was interesting to me that we largely liked (and disliked) the same entries, but often for different reasons. To deal with the unique projection of VIIRS, I used ENVI’s Reproject GLT with Bowtie Correction function to import the data. Tom Patterson, a cartographer with the National Park Service, updates Imhof’s ideas on Shaded Relief: Ideas and Techniques about Relief Presentation on Maps. Part 5: Tools & Techniques, (This series on the use of color in data visualization is being cross-posted on visual.ly. Practitioners (NASA/MODIS. A sequential palette that varies uniformly in lightness will still be readable by someone with color deficient vision (or a black and white print), regardless of the hue. Either use this sample data (184 MB ZIP archive) of the Oregon Cascades, or dip into the Landsat archive with my tutorial for Earth Explorer. Silver (It’s still a bit bright & saturated for my taste, though.). Data courtesy Marc Imhoff of NASA GSFC and Christopher Elvidge of NOAA NGDC. Robert or Rob Simmons may refer to: . For the most part use white or light gray as the central shade. Connecting Color to Meaning Photo courtesy of NASA. A more naturalistic palette for phytoplankton (more or less a type of ocean vegetation) trends from dark blue for barren ocean, through turquoise, green, and yellow for increasing concentrations of the tiny plants and algae. LC80450292013225LGN00_BQA.TIF Bruce Linbloom provides tools to translate between color spaces—and the math behind them. In my mind the best place to start is Color Brewer. One: Seeing Equinoxes and Solstices from Space Photograph by Bill White for NASA. (A combination of the compact areas of light color and very sharp boundaries, I think.) LC80450292013225LGN00_B6.TIF The image on the phone's startup screen was one he had designed. I find it helpful to walk away every once in a while to let my eyes relax, and reset my innate color balance: if you stare at one image for too long it will begin to look “right”, even with a pronounced color cast. The famous "Blue Marble" was taken by the Apollo 17 crew on December 7, 1972 and this was taken from the distance of around 45,000 kilometers (28,000 miles). As Simmon clicked and dragged, the image clarified. This will bring up the Color Table window. The text that accompanies the images points out that while there are many complex atmospheric factors that produce heat waves, scientists agree that global warming has made it more likely for heat waves and large fires to occur. All built with modern web technologies that provide instantaneous feedback and an elegant user interface. There are several types of data, each suited to different types of display. Mike Bostock @mbostock Donald Norman, Emotional Design. It’s also useful for choosing colors for different categories of data that’s not spatial: line graphs, dot plots, or grouped bar charts, for example. Photo courtesy of NASA. It may be trite, but a good visualization is better than the sum of its parts. I find The Development and Rationale of Cross-blended Hypsometric Tints (PDF) particularly fascinating. To show these transitions, keep the change in lightness consistent throughout the palette, but introduce an abrupt shift in hue and/or saturation at the appropriate point. Thanks! I find it easiest to create palettes by typing in the hue manually, then picking a color with the appropriate lightness and chroma. She also pointed out that “color-deficient” is the correct term to use, not “color-blind”. October 22nd, 2013 by Robert Simmon Since its launch in February 2013, Landsat 8 has collected about 400 scenes of the Earth’s surface per day. Some sequential datasets feature one or more physically significant quantities: freezing on a map of temperature, for example. The ColorMine color conversion interface. NASA delays Mars copter flight for tech check. Data Visualizer and Designer Robert Simmon never thought that he would become “Mr. This is typical in a heavily forested region like the Cascades. LC80450292013225LGN00_B3.TIF Photoshop: NASA Earth Observatory has a great tutorial on this, essentially the method we used to process single scenes, by Rob Simmon. Supported by the National Space Biomedical Research Institute (NSBRI) NBPF00014. The Color Brewer Palettes are also implemented in visualization applications and languages like D3, Processing, R, ArcMap, etc. (Astronaut Photograph, carbon the biosphere draws out of the atmosphere. Jonathan Corum (Two Little Ducks) and Anatoly Bondarenko (Texty on Malofiej-22) gave two of the standouts. The image was of a volcano called Rabaul, in Papua New Guinea. Use the “Color Tool, Gamma = 2.2 (PC)” option on both Macs and PCs.) "Climate Change—Our Research". From the Channels Palette (accessed through Photoshop’s Windows menu item) select the Merge Channels command (click on the small downward-pointing triangle in the upper-right corner of the palette). The section on color is short, but essential. It’s the definitive guide to the relativity of color. If you need to display double-digit categories, it’s best to group similar classes together. Apollo 13 (1995) cast and crew credits, including actors, actresses, directors, writers and more. Then enter the Red, Green, Blue values of the first color (178, 24, 43 in our example), hit return, then enter the second color (214, 96, 77). To encode this information in an image format, the reflectance is scaled, and the range of values found in the data are smaller than the full range of values in a 16-bit image. Part 1: Introduction Loyd said a challenge in visualizing science information is catching people's interest. Archived. If the colors converge too abruptly, high-contrast “rivers” of white may appear in the visualization when quantities are near the transition point. These two qualitative color schemes—from I Want Hue (top) and Color Brewer (lower)—each consist of 12 distinct colors. Despite the ubiquity of the Blue Marble, few people realize NASA has viewed the Earth since the agency's creation. OS X can automatically uncompress the files (with default settings) when the archive is downloaded—double-click to unpack the TAR.) Very dark: The raw Landsat 8 scene is so dark because it’s data, not merely an image: the numbers represent the precise amount of light reflected from the Earth’s surface (or a cloud) in each wavelength, a quantity called reflectance. On a recent day, he opened an image file on his 30-inch monitor and set to work on it. Subtleties of Color The unique part about I want hue is that it can generate clusters of analogous colors—colors near each other on the color wheel. But as long as there are new data and images to work with, he plans to continue making graphics that explain how the Earth works. I haven’t used it much, but the results seem a little bit different than the equivalent conversion with chroma.js. Fortunately Landsat 8’s 12-bit data provides a lot of flexibility—adjustments can be quite aggressive before there’s noticeable banding in the image. Although the USGS imagery superficially resembles an RGB picture, it is (in my opinion) inappropriate to call it natural-color. (My ideal tool, at least.). Allow clockwise and counter-clockwise rotation (red-yellow-green-blue or red-magenta-purple-blue). "So what I need to do is manipulate the image to match all the processing that our eyes and brains are doing for us." You add both adjustment layers from the Layer Menu (just hit OK to create the layer): Layer > New Adjustment Layer > Levels… and Layer > New Adjustment Layer > Curves…. Long-term composites reveal global patterns of infrastructure development and energy use. As I’ve hopefully made clear, a perceptual approach to color in data visualization isn’t a matter of aesthetics or personal taste: it’s based on research into human vision and understanding. VIIRS data is aggregated into granules, each acquired over 5 minutes. Illustration by Rob Simmon. OK, not that radically different. Support multiple display color spaces: sRGB, Adobe RGB, CMYK, etc. Last week I had the privilege of helping judge the 22nd Malofiej Awards. China’s Memory Hole: The Images Erased From Sina Weibo (ProPublica) I rely on engineers and … Click the image to enlarge. How to Interpret a False-Color Satellite Image. "So I try to minimize the bad.". Subtleties of Color http://www.nasa.gov/centers/goddard/about/people/RSimmon.html. Unfortunately I can’t provide any hard and fast rules to design visualizations that are aesthetically pleasing (or even beautiful). Close. Mar 5, 2018. LAB allows two-color ramps, which provides additional options to create palettes appropriate for particular datasets. Perfect for building complex maps with large numbers of categories. The chapter on color in Envisioning Information is dense and convincing, packing an entire textbook’s worth of information into 16 pages. within a certain set of parameters, to include: Have an initial total estimated contract value of $10 million or above "But to get across more complex story, that's really hard. The interface for I want hue, a tool to generate qualitative color palettes derived from a perceptual color space. They also made sure the online jury got our fair share of chocolate croissants, showed us the best pintxos bars in Pamplona, and even provided tips on surviving a run with the bulls [train, wear white, and run sober (which should’t be that hard, considering it starts at 8:00 a.m.! Bruce MacEvoy’s web site is primarily about painting with watercolors, and has outstanding sections on color theory and color vision. Then select Image > Mode > Indexed Color. No actual footage of round 1,000 mph spinning Earth exists to this day despite 65 million dollar a day budget when even a basic phone these days can capture the moon. Matteo Niccoli @My_Carta Znanje ogledov 648 dodan 06. Scientists Studying Vision, Perception, and Visualization "The reason it's so dark is because there are 11 bits of data in a 16-bit file," Simmon said. Steve Vander Ark, Laura Giamfortone, Pam Stilwell Colleagues at NASA Johnson Space Center. Robert (Bob) Simmons. The process is called a “contrast stretch” or “histogram stretch” (since it spreads out the histogram). Choose a minimum and maximum that reveal as much detail as possible, without saturating high or low values. Starting Points. It looks a bit complicated, but it’s not too bad. Choice is limited to the endpoints: the maximum and minimum values to be displayed. Instead of a range of related colors, the palette should consist of colors as distinct from one another as possible. A palette that runs from blue through red to yellow reads more naturally. (And just for kicks, everyone should read Randall Munroe’s xkcd color survey results , which underscores the highly subjective nature of color perception.) These techniques can also be applied to data from other satellites: older Landsats, high-resolution commercial satellites, Terra and Aqua, even aerial photography and false-color imagery. In those cases careful control of lightness, saturation, and hue can enable quick differentiation as well as (mostly) accurate comparisons between datasets. "There's this information overload that people are experiencing, and visualization is a great way to handle that," said Drew Skau, a visualization architect at the Bay Area company Visual.ly, a website for people to create, share and discuss visual content. That is, if there were any pixels with zero reflectance. Get access to our comprehensive, daily coverage of energy and environmental politics and policy. Not too surprising, since L*C*h to RGB conversions are hardly simple. The USGS also distributes imagery they call “natural color,” using shortwave infrared, near infrared, and green light. Why Should Engineers and Scientists Be Worried About Color? (Landsat 8 reflectance data are “top of atmosphere”—the effects of the atmosphere are included. If you need help for what to do on this site, please check on one of the admins here and check the Manual of Style page and Policies.Enjoy your stay! This ocean temperature map uses rose and yellow to distinguish the warm waters that can sustain tropical cyclones from cool water, colored blue. Traveling at the same speed as Earth's rotation keeps these so-called geostationary satellites perfectly positioned to maintain constant watch over an entire region. All of these tools generate a small number of colors, that then need to be blended to create smooth palettes. Bob Simmons is vice president, Defense, Space & Security, for Boeing Government Operations.
