My aim is to indentify ecological corridors and for this I´m doing a habitat suitability analysis. I´m using the Corine LandCover raster layer (100x100m) and would like to create buffers around the attributes 'artifical surface'. Artificial surfaces do not display suitable habitat and have a light and noise disturbance range of 100m. Hence I would like to draw 100m buffers around these cells. However, the Buffer tool only works with poylgons and if I use the Expand tool it always shuts down the whole ArcMap program, when I start to run it. I also tried the Euclidean distance tool but my layer contains many different landcover attributes and not just the artifical surfaces, so somewhere I have to 'tell' that I only want buffer around artificial surfaces. Does anyone know how I can do this?
Thanks in advance
PS: I´m quite a beginner with ArcGIS, so please keep it simple (if possible) .
