 "description": "<DIV STYLE=\"text-align:Left;\"><DIV><DIV><P><SPAN>This data set is one component of a digital terrain model (DTM) for St. Johns County. The dataset is comprised of mass points, 2-D and 3-D breakline features, 1-foot and 2-foot contours, ground control, vertical test points, and a footprint of the data set, in the ESRI ArcGIS File Geodatabase format. In accordance with the counties specifications, the following breakline features are contained within the database: closed water bodies (lakes, reservoirs, etc) as 3-D polygons; linear hydrographic features (streams, shorelines, canals, swales, embankments, etc) as 3-D breaklines; coastal shorelines as 3-D linear features; edge of pavement road features as 3-D breakines; soft features (ridges, valleys, etc.) as 3-D breaklines; low confidence areas as 2-D polygons; island features as 3-D polygons; overpasses and bridges as 3-D breaklines. Contours were generated from a keypoint DEM and meet National Map Accuracy Standards. The LiDAR masspoints are delivered in the LAS file format based on the counties 5,000' by 5,000' grid. Breakline features were captured to develop a hydrologically correct DTM.<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>",
