High-Resolution Radar Imagery, Digital Elevation Models, and Related GIS Layers for Barrow, Alaska, USA: File List

DVD 1: Contrast-stretched ORRI tiles
DVD 2: Barrow Peninsula ArcInfo grid layers
DVD 3: Barrow Peninsula floating-point binary layers
DVD 4: Unprocessed Intermap IFSAR tiles
DVD 5: Barrow Triangle subsetted layers

.html, .xml, .txt: Federal Geographic Data Committee (FGDC) metadata
.bil: 32-bit IEEE floating-point, big-endian, band-interleaved by line (BIL), binary file
.hdr: ArcInfo header file
.prj: ArcInfo projection file
.tfw: GeoTIFF world file
.dbf, .prj, .sbn, .sbx, .shx: ESRI Shapefiles
.flt: 32-bit IEEE signed floating-point binary file

File naming convention
File names for ORRI tiles are keyed to the USGS 15-minute topographic maps. For example, "bara2nwqs.tif" is the tile for the northwest portion of the Barrow A2 quadrangle. For more information, see "ifsar_filenames.txt" on DVD 4.

File names for GIS layers of the Barrow Peninsula begin with "bp." File names for GIS layers for the smaller area of the Barrow Triangle begin with "bt." Names for most of the raster layers also include a number indicating horizontal resolution. For example, "bp05_dsm" is the full-resolution version of the DSM with 5 m grid-cell spacing.


Follow the links in the tables below to view FGDC metadata, which provide details about specific data layers, including data sources, processing, data format, spatial and temporal resolution, extent, projection, and datum.
