I have 3 band multispectral raster imagery over a vineyard from which i have created a number of indices e.g. NDVI. The data is fairly high resolution (5cm/pixel) so shows a lot of along vine and across vine variation. For visualisation (and actual use and actioning of the data) i would like to be able to isolate the actual vines from the background (they obviously stand out really well as they are irrigated and are easily separated with the correct thresholds set) and then interpolate the average between the vine rows to show broad scale variation across the vineyard. Does anyone have any ideas how i might do this in the QGIS GUI environment?
