I have two collections of shapefiles:
1 - postal codes, administrative and political areas
2 - various land use categories like parks & allotments, and points like trees
I want to produce statistics on the area of those land use categories broken down by postal code, admin & political area, and the number of points by the same means. For example, there are 4.1ha of park in SE15, 879 trees in SE22, and so on.
I am using QGIS. I've processed my raw data to get all the shapefiles ready, but after much fruitless searching around on this and other web sites I can't see a way to do this.
