Support for measured geometries in drivers
The support for measured geometries has been implemented in the core for GDAL 2.1.
However, it will take some time for the support to be implemented / work in production ready quality in the drivers.
On this page the work is described.
Utilities
ogr2ogr :
- -dim was extended to support XY, XYZ, XYM, and XYZM (discussion: https://lists.osgeo.org/pipermail/gdal-dev/2016-February/043728.html)
- -nlt now supports M and ZM suffixes thanks to enhancement to OGRFromOGCGeomType
ogrinfo:
- -geom was extended to support WKT and ISO_WKT and the latter was set as the default (discussion: https://lists.osgeo.org/pipermail/gdal-dev/2016-February/043734.html)
