DOGAMI Lidar Publications
DOGAMI provides lidar data in several forms. Purchase DOGAMI publications through the Nature of the Northwest Information Center.
Lidar Data Quadrangles (LDQ)
LDQ publications are DATA SETS. DOGAMI Lidar Data Quadrangle Series publications 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. Grid data must be viewed using specialty GIS software (e.g., ESRI ArcGIS; Microstation TerraSolid; VLS LIDAR Analyst; IDL/ENVI; ERDAS IMAGINE; Intergraph GeoMedia). 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.-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.

Looking for point cloud data? Lidar ASCII point data are available in LAS format via the NOAA Coastal Services LDART website: NOAA Topographic Change Mapping site.
Lidar Imagery Series (LIS)
LIS publications are PDFs. DOGAMI Lidar Imagery Series publications show bare-earth and highest-hit imagery produced from lidar data. A publication consists of 4 PDFs representing NW, NE, SW, and SE quarters of a 7.5-minute quadrangle. PDF dimensions are 36 inches x 60 inches.
