Cartography

The term Cadastral refers to surveys that document the boundaries of land ownership, by the production of documents, diagrams, sketches, plans (plats in USA), charts, and maps. In cooperation with the Leon County Property Appraisers Office, TLCGIS maintains a cadastral themed basemap that is specifically intended to display property boundaries, measurements, and numbering systems.

In our Hybrid Imagery basemap we've combined our high resolution digital ortho-photography with an overlay of streets, labels, landmarks, and boundaries to provide spatial context for the end user.

A shaded relief map uses transparency to combine a hillshade raster with a digital elevation model (DEM). This allows that both data sources can be seen merged together. The DEM provides elevation information using color shading and the hillshade provides texture to the landscape to make changes in relief more interpretable.

Often referred to as G-Map due to its resemblance to a google street map, the TLCGIS Street Map is a basemap that displays basic street, boundary, and landmark information from a countywide scale down to a street level scale. This map also includes rooftop address labels beginning at a typical neighborhood scale.

TLCGIS provides printed map products that are used by the Public Defender, State Attorney, & the 2^nd Judicial Circuit.

Whether it be a county map displayed on a commissioner’s wall or a poster of Historic Black Churches for the Meek Eaton Black Archives at FAMU, TLCGIS is ready to create eye-catching visual displays.

The National Flood Insurance Program's (NFIP) Community Rating System (CRS) is a voluntary incentive program that recognizes and encourages community floodplain management activities that exceed the minimum NFIP requirements. As a result, flood insurance premium rates are discounted to reflect the reduced flood risk resulting from the community actions meeting the three goals of the CRS:

1. Reduce flood damage to insurable property;
2. Strengthen and support the insurance aspects of the NFIP, and
3. Encourage a comprehensive approach to floodplain management.
