I would like to draw 100m buffers around particular raster cells (artificial surfaces) in my LandCover raster layer in ArcMap10.2. The Buffer tool only works with polygon and the Expand tool always crashes the whole ArcMap, because its too much data, I think. That´s probably because the expand tool wants to create buffers around every single 100x100m raster cell, if I understand it right. However many of the cells, displaying artificial surfaces, are next to each other, so I only want a Buffer around these cell groups and not around every single cell. Does anyone knows how I can do this?
You can use Expand to buffer raster "zones" that represent specific values in the raster.
Buffers value 10 by 3 cells Expand("landcover", 3, )
You can use the euclidean distance tool, see:
So, I solved my problem in the way that I actually converted my Raster data into Polygon, draw Buffer around it with the Buffer tool and then converted it back into Raster.
