USGS-FISC St. Petersburg Fall 2007vector digital dataOpen File Report2007-1377St. Petersburg, FLUSGSThe USGS, in cooperation with the National Park Service (NPS) and the National Aeronautics and Space Administration (NASA), is to provide the coastal management community with usable, useful digital elevation products. The USGS processes aircraft lidar data (provided by NASA), develops software tools and algorithms to use and analyze the data and make products available to the coastal management community through a variety of media, including the internet, CD-ROMs, DVDs and data reports.EAARL Topography-Gulf Islands National Seashore-MississippiFirstnonecontourGIS contour lines of Gulf Islands National Seashore derived from a Lidar GeoTIFF file.This contour shapefile was generated from a Lidar GeoTIFF. It shows contour lines at 1 meter intervals, and will be used to aid in the interpretation and display of Lidar data files.See the source Lidar GeoTIFF tile for more specific accuracy information.en20050901, 20050903, 20050904, 20050907, 20050908REQUIRED: The year (and optionally month, or month and day) for which the data set corresponds to the ground.ground conditionUnknown-88.973993-88.95311430.21299730.207094310001.500000312001.5000003343380.5000003344000.500000NONEContour mapelevation changeGulf Islands National SeashoreMississippiGulf of Mexicobare earth topographyAny use of these data signifies a user's agreement to comprehension and compliance of the USGS Standard Disclaimer.

Quality checks are built into the data-processing software.Contour lines break where there was no data (value of -100) in the original Lidar tiles.Raw elevation measurements have been determined to be within 1.5 meter horizontal accuracy. Processing steps (grid interpolation) may introduce additional error which has not been tested at the time of this publication.Elevations of the DEM are vertically consistent with the point elevation data, +/- 15cm.computer program20050901, 20050903, 20050904, 20050907, 20050908ground conditionThe Lidar GeoTIFF data was too coarse to create aesthetically pleasing contours. A Neighborhood Statistics operation was run on the Lidar GeoTIFF file in ARCMap. The settings for the Neighborhood Statistics operation were a 14x14 cell rectangle, using the mean as the statistic type and then output to a temporary raster grid.Spring 2007National Park Service South Florida/Caribbean NetworkIris WilsonResearch Assistantmailing and physical address
