(WSI)/Quantum Spatial using an Optech Orion M300 (1064-nm wavelength) lidar sensor on January 21, 2014. Purpose: The purpose of this project was to produce a highly detailed and accurate digital elevation map for Anegada, British Virgin Islands for use as a management tool and to make these data available to natural-resource managers and research scientists. These data were collected to fulfill a contract by the U.S. Geological Survey, in collaboration with the Puget Sound LiDAR Consortium. Supplemental_Information: According to the contractor, the processed data products are used to aid in the identification of fault patterns and signs of historical seismic activity on the island.

Sharing of new data layers developed directly from these data would also be appreciated by the U.S. Geological Survey staff. Users should be aware that comparisons with other datasets for the same area from other periods may be inaccurate because of inconsistencies resulting from changes in photointerpretation, mapping conventions, and digital processes over time. These data are not legal documents and are not to be used as such. Security_Information: Security_Classification_System: Unclassified Security_Classification: Unclassified Security_Handling_Description: None Native_Data_Set_Environment: Microsoft Windows 7 Enterprise Service Pack 1; Esri ArcCatalog 10.2.2.3552 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Logical_Consistency_Report: WSI/Quantum Spatial reports that data cover the entire area specified for this project. Missing areas are representated by a "NoData" value of -32,767; these areas correspond with lack of bare-earth data within the survey bounds. Completeness_Report: WSI/Quantum Spatial reported that the dataset is considered complete for the information presented, as described by the abstract. Useres are advised to read the rest of the metadata record carefully for additional details. Positional_Accuracy: Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: WSI/Quantum Spatial reports that the Fundamental Vertical Accuracy (FVA) was computed by comparing the known Real Time Kinematic (RTK) ground control point data collected on open, bare earth surfaces with level slope to the triangulated ground surface generated by the LiDAR points. They report that the root mean square error (RMSE) was computed to be 0.021 m.
