Software and data produced or maintained by Bruce Raup

Software

• IMCORR (image cross-correlation software)
• VelVIEW (vector editing software for use with IMCORR)

  Small Utilities

• make_small-circle, a perl program to generate geographic circles centered on a specified point and with a specified radius. Works with and depends on GMT.
• Examples of Proj.4 usage

Data

Digital Chart of the World state and country boundaries

GLIMS ASTER acquisition polygons (STAR polygons)

These boundaries were compiled from the Digital Chart of the World, the World Glacier Monitoring Service's World Glacier Inventory, the National Snow and Ice Data Center's Eurasian Glacier Inventory, a GIS database of Alaskan glaciers from Wrangell St. Elias National Park, and miscellaneous atlases for a few small glaciers.

• GMT multi-segment ASCII file format (gzipped)
  • ice_all_dd.gmt.gz All land ice at highest detail. Also includes a few 60 km boxes where glaciers are known to exist, but where glacier polygons weren't available. Lon/lat in decimal degrees.
  • glnobox.gmt.gz Same as above, but without the 60 km boxes.
  • br_ice_buff2dd.gmt.gz Lower resolution polygons. Probably still includes the 60 km boxes.
• Shapefile format
  • glac_dcw.tgz This is a gzipped tar file. Note that it was created for the purposes described in the IEEE article above. It contains a few box-shaped polygons that were inserted to trigger ASTER image acquisitions there. These obviously don't represent the shape of the glaciers in those spots.
