SCC GIS provides public access to parcel, cadastral, and tax data using an interactive cadastral mapping web site. Links to this site are available from this web page (see Interactive Parcel Map), the Assessor’s web page, and the web page maintained by the County’s Mapping and Platting department. The Assessor’s web link provides more detailed real property and tax information in a report format that can be used to query specific parcels using the mapping system.
SCC GIS maintains a GPS beacon, radio transmitter, and a geographic reference system for surveying and other applications requiring precise location information. Correction data are provided on this web site for post-processing operations (see Control Monuments). The radio transmitter is licensed to operate at 20 watts on 453.10mh. Control monument pairs have been located throughout the County to support data collection and specifically near right-of-ways for convenient access.
SCC GIS supports spatial data users with consulting, help desk, and software training. Workshops and seminars are available to County departments on specific topics related to business processes that rely on spatial and other data stored in the data warehouse. In addition, SCC GIS convenes user group meetings which provide updates on data, access methods, and end-user applications. These meetings are open to County departments and registered guests.
The enterprise geodatabase warehouse is accessible through data connections maintained by SCC GIS. These connections may be available using Virtual Private Network (VPN) authentication hardware and software for users accessing the system from computers outside of the St. Clair County network domain. Data layers from the warehouse may be purchased as shape files or personal geodatabases which require the use of GIS software. Aerial imagery is available in MrSID and TIFF file formats. Also, custom mapping and reports are available and provided on a time and material cost basis.
SCC GIS provides consulting services to outside agencies and organizations engaged in data collection, planning, and service delivery assessments based on time and material agreements.
