Geographic Information Systems (GIS)

Geographic Information Systems (GIS) and the important spatial data they contain can be critical tools in emergency management. During an emergency or disaster in Missouri, SEMA’s GIS Program harnesses GIS technology to better assess and visualize damage statewide, develop response priorities and logistics planning, and to track progress throughout the response. SEMA GIS also provides important geospatial services that aid in mitigation efforts.

The United States National Grid (USNG) was approved by the Missouri GIS Advisory Committee in May 2009 as a standard reference grid for emergency response. The intent of this standard is to improve interoperability between all jurisdictions during emergency events.

Disaster Support Atlases: Map books with USNG grids have being created for all counties in Missouri in GEOpdf format. Find more information and download these files here.

ESRI offers a free add-on for ArcGIS Desktop for working with USNG. "U.S. National Grid Tools for ArcGIS" allows users to plot a national grid on a map, locate coordinates, and view multiple coordinate systems. Download ESRI USNG tool »

Delta State University has created a video for creating USNG mapbooks in ArcView. The video shows how to download USNG data and use the free ESRI DSMapBook extension to create mapbooks for a county. See Video »
