While the AHPS display allows for the use of interactive toggles with the image, AHPS data can also be utilized within GIS software. This page links to "Shapefiles" and "KMZ" files (generated every 15 minutes) which are compressed "KML" files compatible with several GIS software applications. A list of some of the software applications that support Shapefiles and KML can be found HERE or, visit the NWS website Standards Description Website which explains KML in more detail.
