This year for Earth Observation Day we had a mini mapathon and a speaker. Our mapathon efforts focused on a project in Puerto Rico that was mapping features as part of the Hurricane Maria recovery efforts. Then Daryl Herzmann presented about the Iowa Environmental Mesonet (IEM), a storehouse and distribution center for weather, satellite, and transportation data for the US. Daryl gave a brief history of IEM along with highlighting many of its uses. Click here to view Daryl’s powerpoint.
