Portland, Oregon: A new geologic digital data series for the southern Oregon coast is being released today by the Oregon Department of Geology and Mineral Industries (DOGAMI).

The Lidar Data Quadrangle Series (LDQ) This release in the LDQ series (data only) covers both individual and bundled USGS quadrangles along the coast from Brookings to Florence and huge swaths of inland coastal areas. This data is part of a data publication series that will eventually provide complete lidar data for most of the inhabited areas of the state.

Please refer to the attached map for details or go online to see a list of the USGS quads and data available at: http://www.oregongeology.org

The data in the LDQ series however, are designed specifically for use with specialty Geographic Information Systems (GIS) software and include only raster based data; in other words, a file with a regular grid of elevation values. Lidar data originate as large numbers of measured points which have been filtered and processed to produce the rasters in the LDQs. The point data (point cloud) requires special software and expertise to use, and creates very large files, so it is not included in this publication series.   You can learn more about the collection of lidar data in Oregon and the Oregon Lidar Consortium online at:
