Sample ASTER Digital Terrain Feature (DTF) Product, NASA/EP-ESIP
Listed in NASA Earthdata CMR
MRJ Technology Solutions, Inc. was designated a NASA Type 3 Working Proto-type Earth Science Information Partner (WP-ESIP) to investigate the application of the Advanced Spaceborne Thermal Emission and Reflection radiometer (ASTER) data for producing enhanced terrain products.
Description
ASTER is an instrument scheduled to fly on-board the NASA Earth Observation System (EOS) satellite EOS AM-1. The ASTER data set was simulated from airborne flights of the Airborne Visible and Infrared Imaging Spectrometer (AVIRIS) and the Thermal Infrared Multispectral Scanner (TIMS).
MRJ's Digital Terrain Features (DTF) product is a combination of vector and raster GIS layers which describe terrain features. The Death Valley data set is a simulation of ASTER Level 1B data in units of radiance using the nominal instrument gain settings. It is arranged in three smaller data sets, one for each subsystem (Visible Near Infrared (VNIR), ShortWave Infrared (SWIR), Thermal Infrared (TIR).) The data set was created from spectrally resampled AVIRIS images and TIMS images, that were then co-registered, and spatially resampled to the appropriate ASTER pixel sizes for each subsystem (15m - VNIR, 30m - SWIR, and 90m -TIR).

The SWIR and TIR data sets were then sized up using pixel replication to have the same number of samples and lines as the VNIR data set. The area covered by the data is 12 x 51 km. The data set was registered to USGS 1:100,000 Digitial Line Graph (DLG) vector data.
The data set consists of land cover classification within Death Valley, digital elevation from 7.5 minute USGS Digital Elevation Model (DEM), slope and relief from the digital elevation, transportation and hydrography vector layers from the USGS 1:1,000,000 DLG.
