GIS Map Services

COSA provides various GIS map services for public use. These services are distributed using ArcGIS Server 9.3 technology. These services require software capable of consuming map services. All data is refreshed daily.

Most GIS and CAD software programs allow users to directly link to these map services and view the data without downloading the data. The benefit is that the web service is “live” data and theoretically, never out of date.

We do not provide technical support for software used to view these services.
