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.
