IEM

The Iowa Environmental Mesonet (IEM) GIS Mainpage provides extensive information and resources for manipulating spatially referenced data. It naturally integrates IEM data into various GIS applications, making environmental datasets accessible and usable. Key offerings include a "GIS Ready" image which signifies data links compatible with most GIS systems.

The site features a Presentations & Docs section with resources like a NEXRAD + Mapserver HOWTO, an archive of GIS-related talks, and IEM RASTERs Lookup Tables for converting raster data into actual values. Additionally, a suite of Web Applications is available, including tools for viewing NEXRAD with warnings, COOP Daily Extremes and Averages, Dynamic Plotting, an IEM Site Locator, and a NEXRAD Mosaic by Year viewer.

Further, the platform curates a valuable list of external GIS links to resources such as the US Drought Monitor, NCDC Severe Weather Data Inventory, GIS Severe Weather reports, NCDC GIS Portal, NCEI's Display and Conversion Tools, NSSL Google Earth Data, Oregon State PRISM, USDA PRISM data, Iowa Natural Resources Geographic Information System (NRGIS), and NOAA's GIS and NWS warnings work.
