GeoComm proposes ESRI-based GIS data management software, GeoLynx DMS. Using GeoLynx DMS you will immediately benefit from the automated tools designed specifically for developing and maintaining high quality GIS data and Master Street Address Guides (MSAG). By installing GeoLynx DMS a toolbar will display within ESRI ArcMap, exposing features and functions specific to maintenance of these two primary data components used for 9-1-1 call plotting in dispatch GIS systems and CAD. These features and functions will enable efficient updates to GIS data layers, such as road centerline layers and address point layers, and your MSAG.
