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.
- A-CAP: The Antarctic Cryosphere Access Portal: Search, browse, compare, and download functions are available or under development. For more information on the project, see About A-CAP.
