When I tried to create staged Raster buffers with the r.buffer function from the GRASS toolbox it always gave me a nodata value for everything outside the defined buffers. I tried to set a final buffer stage about the size of the max Work-enviroment size (about 50 kilometres).</span></div><div><span style="font-family: Calibri, 'Slate Pro', sans-serif, sans-serif;"> That works till up close to the borders I need, but whenever it get's so close one pixel of the buffer would technically overlap the boundary it just makes the entire outer buffer stage nodata. </span></div><div><span style="font-family: Calibri, 'Slate Pro', sans-serif, sans-serif;"><br></span></div><div><span style="font-family: Calibri, 'Slate Pro', sans-serif, sans-serif;">Is there any direct way to just have it fill the entire space set by the workplace boundaries outside the defined buffer stages with a value?</span></div><div><span style="font-family: Calibri, 'Slate Pro', sans-serif, sans-serif;"><br></span></div><div><span style="font-family: Calibri, 'Slate Pro', sans-serif, sans-serif;">Thanks in advance</span></div><div><span style="font-family: Calibri, 'Slate Pro', sans-serif, sans-serif;">Jeffrey Rhodes</span></div><div><br></div><div></div></body></html>
