Support for measured geometries in drivers

The support for measured geometries in drivers has been implemented.

However, it will take some time for the support to be implemented / work in production ready quality.

On this page the work is described.

Memory

Status

• Implemented, no known issues

Existing tests

• pass

New tests

• swig/perl/t/00-measures-02.t pass without skips

ESRI Shapefile

Status

• Implemented
• See discussion on the list: when XYM or, especially, XYZM shapefiles a opened, the result should actually be XY or XYZ if M is not used.

Existing tests

• test_ogrogr_py skips three tests

New tests

• swig/perl/t/00-measures-03.t pass without skips

PostgreSQL

Status

• Implemented
• The driver often uses the numeric dimension (2,3,4) to determine the geometry flags (Z,M) and 3 is ambiguous since it can be XYM or XYZ, the situation probably causes bugs

Existing tests

• pass

New tests

• swig/perl/t/00-measures-04.t pass without skips
