I have a vector layer of habitats. Each feature belongs to a category and has its area calculated. I'm trying to find out the total area of each type of habitat.
I've looked at QGIS "Statistics by categories" which gives everything but the Sum of each category.
The GroupStats plugin looks like it would do it, but I can't get the "calculate" button to activate.
I'm new to QGIS tools/scripts etc but happy to try to modify an existing tool but haven't yet found where they are or how to do this. If anyone can help either directly or point me in the right direction, I'd appreciate it.
