Kuparuk River watershed DEM
We received raw data at 2.5 m posting, and resampled the data to 5 m and 25 m posting as described in Data Processing. The resampled data was created using cubic convolution (CC) resampling method in Erdas Imagine. We also performed a resolution merge in Erdas Imagine to fuse the ORRI data with a Landsat image for the Upper Kuparuk, the resulting file is included at 2.5 m and 5 m posting. The data is provided in Erdas Imagine *.img format and in GeoTIFF format. The 2.5 m posting ORRI data for the entire Kuparuk basin is not provided in GeoTIFF format as the filesize would exceed the 2GB TIFF limit.
The following table contanis the file names and locations for the Upper Kuparuk subset:
