Supplemental Information

This metadata file was written to document and describe, as a whole, all the nDSM model files generated for this project. The original metadata files provided by Watershed Sciences, Inc are also included in the download package and may provide additional useful information that is specific to each file. The metadata files provided by Watershed Sciences, Inc. have not been reviewed for accuracy or compliance with FGDC standards. For each data delivery area, reports documenting data collection methodology, accuracy, and quality control were provided by Watershed Sciences and the Oregon Department of Geology and Mineral Industries (DOGAMI). These reports have been combined into single comprehensive reports organized by delivery region. The lidar QC report (the comprehensive report from DOGAMI) and the lidar delivery report (the comprehensive report from Watershed Sciences) can be found at >. Information about the quadrangles included in individual delivery regions can be found in the lidar delivery index report included with the data download. The DGGS metadata standard extends the FGDC standard to include several elements that are required to facilitate internal data management. These elements are referred to as layers. This dataset is described as a single layer titled:
>ndsm The normalized digital surface models (nDSM) represent the above ground elevation of the highest laser return with all vegetation included.

Metadata

Metadata is the data about the data and answers "Who, what, when, where, how and why?" about the dataset. Please see the DGGS Metadata README page for information about our metadata.
