What Are GIS Maps & Why They Matter

What GIS Maps Include

Parcel Boundaries and Legal Descriptions

GIS maps show precise parcel boundaries using survey-grade coordinates. Each lot includes a legal description from the deed, such as metes and bounds or lot-and-block. These boundaries match county records and plat maps. Users can compare map lines with fences or markers on-site. Disputes over property lines often start with GIS verification. The system links to scanned plat books for historical context. Accurate boundaries prevent encroachment issues. Real estate agents rely on this data for listings. Homeowners use it before building fences or sheds. All boundary data comes from certified surveys and recorded deeds.

Lot Dimensions, Zoning, and Land Use Layers

Every parcel displays lot dimensions in feet or meters. Zoning codes appear as colored overlays—residential, commercial, agricultural, or mixed-use. Users can click to see permitted uses, height limits, and setback rules. Land use layers show parks, wetlands, or conservation areas. These help determine development potential. For example, a resident might check if a backyard pool meets zoning rules. Developers analyze multiple lots for rezoning opportunities. The system updates zoning maps after county commission approvals. Layer toggles let users customize views. This feature supports smart planning and avoids costly permit denials.

Property Ownership and Historical Records

Ownership names and mailing addresses are listed for each parcel. The system links to deed history, showing past sales and transfers. Users can view grantor-grantee records from the last 20 years.

Historical data includes foreclosure notices and tax deeds. Records are updated weekly from the Clerk’s office. Some entries include scanned PDFs of original documents.

Historical tax trends appear in chart form. This helps buyers estimate future costs. Homeowners compare their assessment to neighbors for fairness. The system updates values after annual reassessments in January. Market data comes from recent sales of similar properties. Tax records sync with the Collector’s office monthly. Payment deadlines and exemption forms are linked. This transparency builds trust in local government.

How GIS Maps Help Property Owners, Investors, and Professionals

Planning Renovations or Construction
