What is MSDIS Mapper?
MSDIS Mapper Internet Map Server is an on-line mapping utility which enables users who may not be familiar with Geographic Information Systems software to view geo spatial data held by MSDIS for the State of Missouri.  Currently, a limited number of map services are available statewide with some sample maps available at the county level. Expanded services are currently under development. 

The Mapper pages are powered ESRI's ArcIMS software.
