Lidar Data Quadrangles (LDQ)

Standardized sets of lidar data, all in Esri grid format, tiled to USGS 7.5-minute quadrangles and referenced to Ohio Code; Intensity TIFFs tiled to 1/100th 7.5-minute quadrangles and referenced to Ohio Code.

You can also can download LDQ data from the DOGAMI Lidar Data Viewer.

View project area extents, projection information, acquisition dates, sensor types, pulse density, datums, and other information on the viewer.

DOGAMI Lidar Data Quadrangle Series publications require specialty software to view and generally contain a standard set of data files: a bare earth digital elevation model (DEM), a highest hit DEM, and intensity tiff images, all in Esri grid format. Metadata, readme, shapefiles, extents, and 7.5 and 1/100th quad index files are also included. All grid data have been tiled to USGS 7.5-minute quadrangles and referenced to Ohio Code (e.g., 45122D5 = Gladstone quadrangle). Intensity TIFFs have been tiled to 1/100th 7.5-minute quads and referenced to Ohio Code (e.g., 45122D5418). Typical DVD file size for an entire quadrangle is 2-4 GB.

Note: Zipped file sizes range from 8 MB to 8 GB, so be patient!
