GIS Data Development

Using the latest technology, DMS captures real-world features and builds attribute databases for custom mapping projects or spatial analysis. All GIS data created is specific to your needs.



Cartography and Map Production

DMS specializes in producing geographically-accurate, aesthetically-pleasing, and often cartographically-complex maps for use in reports, documents, websites, and for public presentation.



Spatial Analysis

Clients gain the most from their GIS data when carefully-designed maps are coupled with numerical summaries. Once GIS data for your area has been developed, DMS can run the required analysis.
