I love maps.
Maps tell convoluted stories in a seemingly simple, clean interface that belies the effort and planning that goes into constructing an understandable map. The one below is one I drew after working for several months in this particular portion of Ecuador, but it is only one of the many, many ways the area could be represented.
During graduate school I was the TA for several courses where map making was one of the essential skills being taught, both old school with a compass and your stride length, and with the newer GIS methods. Even though I had been making maps for various jobs ever since high school and had recently learned how to use ArcGIS, I didn’t realize how difficult it is for many people to understand what makes a map that is useful and pleasant to look at.
A good map, to me, is a work of art, it is something that you want to look at because it is interesting and beautiful on its own visual merits. It is something that draws you in and encourages you to learn new things while tricking you into thinking you are just looking at something pretty.
This page has a partial list of some good mapping and GIS resources. I will be adding to this heavily over time as I have many more sources bookmarked that I need to process. Some of these resources require a login (usually available via a free account) to access the data.
The Weather and Climate page also has some GIS links.
Keep in mind that within the US each state has a publicly accessible GIS clearing house, as do more and more cities.
As with all, please feel free to offer suggestions to especially good and useful resources.

The tool, Scientific Exoplanets Renderer (SER), is not publicly available yet. The page has an example of Earth rendered using this software.
