SNWG Solutions with GIS Capabilities Every two years, the Satellite Needs Working Group (SNWG) conducts a survey to document and communicate the satellite Earth-observing needs of federal agencies to NASA, NOAA, and USGS. By identifying gaps in current Earth observations,
these surveys drive new NASA-directed data products, services, or other investments to support agency decision making. This document describes some GIS solutions developed in response to SNWG surveys and activities.
