DEM data files
SRTM 1x1 degree files in 16-bit big-endian format
Selected TOPSAR DEMs

Orbit files
Envisat precise orbit files by day

Toward standardized data formats
The WInSAR Formats and Standards Committee seeks to develop and publicize commonly-used data formats to ease translation and comparison of InSAR data from disparate sources. This section lists initial efforts toward this goal, and we welcome comments and contributions from the community.
The WINEX format
Sample input parameters for WINEX-compatible processing

Community software
Unmoderated collection of useful insar software
Some scripts and code for processing Envisat data
