Fort Bend County Map Index 25

Covering Harris and Fort Bend Counties, the Zingery Map Company provided standardized maps at 1:12,000 scale with Lambert conformal polyconic projection beginning November 12, 1956. As Fort Bend County grew from predominantly rural to suburban development, the need for a map grid that allowed for greater detail on our publicly available certified tax basemaps and elsewhere became apparent. Although each account still references the original Z Map grid, a grid was created that provided 64 tiles within a single Z-map grid. The first letter is "A" followed by a dash with three additional numeric characters captures the original Z-map naming convention. It is then followed by an alpha/numeric combination that varies based on the number of tiles needed to cover the county.
