Hello,
I try to create a new shapefile AreaShape, from an existing shapefile, grouping the AreaShapes depending on Feature.ColumnValues.
Like this:
ORIGINAL SHAPEFILE
------------------
ID DEP SECTION NO
1 99 AB 1
2 99 AB 2
3 99 AB 3
4 99 AC 1
5 99 AC 2
OUTPUT SHAPEFILE
----------------
ID DEP SECTION
1 99 AB
2 99 AC
I plan on creating an InMemoryLayer with:
- New AreaShapes created using AreaBaseShape.Union
- The ColumnValues copied from the base shapefile.
Then how to save the InMemoryLayer in a shapefile?
or may be, there is a simpler way ...
Thank you for your help.
