Paris Code Sprint 2016 : GDAL Agenda

Discussion and group review topics for the Paris Code Sprint 2016.

Tasks

• Extending RFC 61 - Support for measured geometries :
  • Python testing of new methods
  • Implementation in drivers that support it : PostGIS (if not already completed), SQLite/Spatialite, FileGDB, OpenFileGDB, GPKG, Oracle. Check that it works with CSV, VRT, MEM
  • Check how that works with reprojection. Probably need ogr2ogr hack
  • Review remaining tasks in https://trac.osgeo.org/gdal/wiki/MeasuredGeometriesInDrivers

• Breaking cyclic dependency spatialite->postgis->gdal->spatialite that cause issues in DebianGIS packaging, possibly by dlopen()'ing spatialite

• Improve error handling of libcurl errors and other network errors for vsi* drivers
  • See: https://github.com/mapbox/rasterio/issues/538 for discussion

• Improve performance of ODBC and related drivers ( https://trac.osgeo.org/gdal/ticket/6373 ) - right now if you don't specify table filter it is too slow against large

databases as it seems every table call requeries all metadata of all tables. This I ran into when using ogr-fdw

• • See: https://github.com/pramsey/pgsql-ogr-fdw/issues/50 (but concluded the issue is in GDAL/OGR since querying with ogrinfo and friends is just as slow)

• Configure script for mingw64 ODBC - https://trac.osgeo.org/gdal/ticket/6000
