Add a new metadata (azimuthAnxTime) to Sentinel 1 Model

Summary

New Metadata for Sentinel 1 Model : azimuthAnxTime

Rationale

The metadata will be used for S1 IW mode to select burst between two images.

Implementation Details

Classes and files

Four classes was changed :

• ossimSarSensorModelPathsAndKeys : New keys
• ossimSarSensorModel : Spread BurstRecordType
• ossimSentinel1Model : Get the new metadata and fill the BurstRecordType
• ossimCosmoSkymedModel : Fill BurstRecordType with a default value for this metadata (0)

NB : The version of geom file can be checked by some applications and an exeception can be thrown if the third version (at least) is required.

Tests

The application ReadImageInfo was used to visualize the new geom file for Sentinel 1 data.
