Abstract The U.S. Geological Survey (USGS) intends to use this specification to acquire and procure light detection and ranging (lidar) data, and to create consistency across all USGS National Geospatial Program (NGP) and partner funded lidar collections, in particular those undertaken in support of the National Elevation Dataset (NED) (Gesch, 2007). Unlike most other lidar data procurement specifications, which are focused on the products derived from lidar point cloud data; such as the bare-earth Digital Elevation Model (DEM), this specification places unprecedented emphasis on the handling of the source lidar point cloud data. The goal of this document is to assure that the complete acquired source dataset, including the data, metadata, descriptive documentation, quality information, and ancillary datacollected in accordance with the minimum parameters specified withinremains intact and viable to support the wide variety of DEM and non-DEM science and mapping applications that benefit from lidar technology. In the absence of other comprehensive specifications or standards, the USGS NGP hopes that this specification will, to the greatest degree practical, be adopted by other USGS programs and disciplines, and by other federal agencies. Adherence to the following minimum specifications ensures that bare-earth DEMs derived from lidar data are suitable for ingestion into the NED at the 1/9 arc-second resolution, and can be resampled for use in the 1/3 and 1 arc-second NED resolutions. It also ensures that the point cloud source data are handled in a consistent manner by all data providers and delivered to the USGS in clearly defined formats. This allows straight-forward ingestion into lidar data management systems such as the Center for Lidar Information, Coordination, and Knowledge (CLICK) (Stoker and others, 2006) and simplifies subsequent use of the source data by the broader user community, particularly with regard to cross-collection analysis. It must be emphasized that this is a base specification, defining minimum parameters for acceptance of the acquired lidar data. It is expected that local conditions in any given project area, specialized applications for the data, or the preferences of cooperators, may mandate more stringent requirements. The USGS encourages the collection of more detailed, accurate, or value-added data.
