 "description": "<div style='text-align:Left;'><div><div><p><span><span>This dataset provides a statewide collection of building footprint polygons for Mississippi. The core geometry was derived from BING Raster imagery by Microsoft. MARIS obtained the original dataset in JSON format and converted it to a WGS84 Geographic Coordinate System shapefile using MapShaper software. The dataset was subsequently reprojected into the NAD 1983 Mississippi Transverse Mercator (MSTM) coordinate system (Meters). The 2022 release contains approximately 1,507,496 building footprint polygons statewide.<\/span><\/span><\/p><p style='font-style:italic;'><span style='font-weight:bold;'><span>Key Components:<\/span><\/span><\/p><ul><li><p><span style='font-weight:bold;'><span>Geometry<\/span><\/span><span><span>: The dataset contains <\/span><\/span><span style='font-weight:bold;'><span>over 1.5 million structure<\/span><\/span><span><span> polygons representing various building footprints.
