qgis - How to work out sqft/m of land coverage?


I am currently self teaching myself on qgis whilst volenteering on a project on a river catchment and your help is hugely appreciated!


I need to be able to work out the percentage of land cover or sqft/m coverage. I have all the land uses on as a vector layer over my river catchment.


Many thanks and let me know what other info i need to give as a newbie!



Answer



Look into Group Stats plugin. I've described it's usage in http://anitagraser.com/2013/02/02/group-stats-tutorial/.



You can put the land use class in rows, the "sum" operator in columns and "area" in value to calculate the sum of all areas per land use class.
