Fun with GIS #105: Ecoregions, Drought, and iPad
A year ago, I wrote a blog about using ArcGIS Online to explore ecoregions, and doing it on an iPad, in addition to a regular computer. I want to enhance the map by adding another key layer: drought status. I’m interested in learning which ecoregions face a near-term issue.
The U.S. government runs a portal about drought, with maps, data, news, and links. But what if you just want to drought data added into your ecoregion map? Think back to another recent blog entry that walked through finding and adding special services. This time, we need to find some drought data. By searching the information, links, and applications at the drought portal, I found the National Climate Data Center’s web service for the Palmer Drought Severity Index. the combined map.
Finally, since the two color layers compete, I used the idea from another blog entry to create a three-panel map, showing a location by terrain, drought, and ecoregion.
