Update Frame Geojson #103

Closed cmarshak closed 1 year ago

cmarshak commented 1 year ago

Uses frame footprints (frames and all overlapping bursts) to ensure that enough DEM is requested. The frames used to determine SLCs are slightly smaller. This is discussed here.

So,

  1. s1_frames_latitude_aligned.geojson.zip determine the processing_extent for ISCE2 - this is the bbox to be submitted in the topsApp XML. This will be slightly smaller than the final GUNW. The GUNW will include all the bursts that overlap with this latitude aligned frame.
  2. s1_gunw_frame_footprints.geojson.zip are the extent determined by taking all intersecting bursts with the above. This geometry will be used to submit extents for getting the DEM since for geocoding the entire GUNW area must be covered.

This image summarizes it: image

Above are two frames. The polygons with transparency are the latitude aligned frames; the solid color outlines are the gunw extents.

Also, updated intersection_geo to gunw_geo or (ifg_geo) because the latter is/are more descriptive of the variable and metadata that is being recorded.
