After upgrading to ArcGIS 10.3 last week, I went through the usual process of reapplying all of my settings and preferences in ArcMap. To expedite this process, a couple years ago I created a list of all of my preferences in ArcMap: toolbars, ArcMap Options, Geoprocessing Options, menu items, Environment Settings, and Advanced ArcMap Settings. At the suggestion of some of my colleagues, here’s the list in full.
But turning them all on at once is not a good idea. This overload of toolbars, many of which are only useful in specific contexts, is one of the reasons Microsoft moved Office to the ribbon-style UI. Esri has implemented the same ribbon in ArcGIS Pro, though I will miss some of the customization aimed at power users.
So for my day-to-day ArcMap work, I have the following toolbars enabled: Standard, Editor, and Snapping in the first row; Tools, Layout, and Labeling in the second row; and Draw and Graphics in the third row. Organizing the toolbars in these rows allows for a comfortable fit in a window that is around 1,200 pixels wide.
When I moved into my apartment in fall 2013, the long wall behind the TV desperately needed some decorations. While playing around with band combinations in some Landsat imagery at work, I stumbled upon an idea: a series of prints of multispectral remote sensing imagery with different band combinations. The series would resemble Warhol’s multicolored Marilyn Monroe prints, except that the striking color palettes would represent actual band combinations used in the remote sensing field to highlight different surface characteristics.
The prints depict a mostly cloud-free view of eastern Massachusetts, Rhode Island, southern New Hampshire, eastern Connecticut, and the tip of Long Island. The prints lack the usual accoutrements of maps like state outlines, legends, north arrows, and scale bars. For this reason, it takes many visitors a minute to realize they are maps and not some kind of abstract print.
I made these prints in ArcGIS using two scenes from the Operational Land Imager (OLI) onboard the $850 million Landsat 8 satellite. The publicly available LC80120302013250LGN00 and LC80120312013250LGN00 scenes were captured sequentially as Landsat 8 passed over from northeast to southwest at 11:30am EDT on Saturday, September 7, 2013. The tilt of the prints occurs because Landsat 8 orbits at a slight angle from due north so it can pass over different parts of the Earth. Luckily, rows 30 and 31 in path 12 of the Landsat Worldwide Reference System include almost all of eastern Massachusetts; only Nantucket and part of Cape Cod are missing.
I’m big fan of the NASA Earth Observatory website run by the Goddard Space Flight Center. Their Image of the Day series showcases stunning imagery and applications of remote sensing every day, in the style of the long-running Astronomy Picture of the Day. They also hold a monthly “puzzler” competition, where they post a satellite image without any annotations and ask readers to identify the location and why it’s interesting. For the December puzzler, they posted the following image:
The scene depicts a valley in a cold climate, with some kind of body of water (or other liquid?) at center. The sinuous shape suggests glacial activity, though this conflicts with the lack of snow and ice. Notably, no vegetation is visible anywhere, making it look very similar to a HiRISE image of Mars. I then thought that this could be the McMurdo Dry Valleys in Antarctica. In college, I saw a number of presentations from professors and graduate students who had conducted research in the Dry Valleys because of the similarities to Martian climate. After only a few minutes of hunting around on Google Maps, I found the location. But what was in the center of the image that looked like a lake?
The Wikipedia page for the McMurdo Dry Valleys lists a number of lakes. I clicked on the link for Don Juan Pond, which was noted to be the most saline of all, and bingo: the image was a perfect match. I quickly wrote up a description and submitted it in the comments section. Lo and behold, I was the first commenter and won the puzzler!
As it turned out, the research paper that inspired the puzzler was coauthored by Brown researchers Jay Dickson and Jim Head. Perhaps it was the memory of one of their presentations that made me think of the Dry Valleys. Either way, what a small world.
