I am attempting to calculate mean NDVI at different time points with 100m and 500m radii of certain co-ordinates. Thus far I have used 'Raster Calculator' to calculate the NDVIs and have used 'Vector -> Geoprocessing Tools -> Fixed distance buffer' to calculate the buffers. My screen looks like:
How do I calculate the mean NDVI for each layer in each buffer?
I am hoping to end up with a 9 column csv table I can then import into R with the column headings:
id; lat; long; ndvi_100m_summer1990; ndvi_500m_summer1990; ndvi_100m_spring1990; ndvi_500m_spring1990; ndvi_100m_summer1991; ndvi_500m_summer1991
