#12 Z/M support for shape files


Saga is superb for working with grids. Its open source structure and its scriptability make it very useful for our day to day grid manipulation. In comparison to the grid-powers we find that the agility to process vector data is far behind the grid powers. While vector data manipulation is possible to a certain extend, there is one big downside to the module functionalities:

ESRI-shapefile data format is not supported fully

I wish for the compatibility with Z/M-data format, meaning that PolyLineZ shapes could be read and written as an example. I have looked into the source code and figured that in shapes_io.cpp the Z/M-information is simply skipped for the moment. Also the shape object does not seem to comprise a 3d point object. Correct me if I am wrong, but this would be a superb feature addition to have in my opinion.

Best wishes and thanks for this lovely software.
