Description
This is a new feature request. Please add support in GDAL/OGR/Shapelib to open a shapefile (.shp) when the corresponding index file (.shx) is missing. This will benefit use cases where the index file is lost, damaged, or never generated.
From my limited reading of the ESRI spec, it seems that the index file contains only redundant information for optimizing read access to the primary shape file. It looks like the internal structure of the primary shape file is fairly easy to traverse.
To whom it may concern, thanks for your consideration.
