Velmap Software Tools

We maintain two software tools at NSIDC that are used to generate and edit displacment vectors from imagery:

  • IMCORR image cross-correlation software
  • Originally written by Mark Fahnestock (Fahnestock, M. A., Scambos, T.A., and Bindschadler, R. A.,1992 Semi-automated ice velocity determination from satellite imagery, Eos, 73, 493.)
  • VELVIEW vector editing software to be used with IMCORR
  • Written by Bruce Raup

We are also developing a new tool called the Antarctic Cryosphere Access Portal, which is a geo-visualization tool for AGDC data and other continent-wide parameters. This tool is still under development so all functionality may not be present.
