I personaly use only some simple average from cells in neighbourhood but collegue tried to do some analysis which needs for computation also cells behind those 8 around.

Re: [Qgis-user] GRASS map calculator bug/feature
Hi, nice to see that the tool is used. I found that you can type anything as constant (Add constant value) but that is just another bug because there should be QDoubleValidator set on that input so I cannot reccomend to use this because that may not work in future (including saved formulas). I would like to avoid the possibility to type anything in map input control because it is not robust enough - user can type wrong map name and r.mapcalc fails. GRASS Tools should not let a user to run a module with parameters which can fail. IMO we can add onother control beside map combo box for cell selection (default 0,0). If you are interested in this feature, please fill a new ticket (enhancement, 0.9). BTW, do you realy need to work with individual cells or do you need just a sum/avg/... from cells in neighbourhood?

[Qgis-user] GRASS map calculator bug/feature
Hi, in QGIS Preview2 (WINDOWS) there was a bug [1] in GRASS map calculator which preserves user to choose layer from list so user had to type name of the layer manually. Recently I've find out that this is nice feature which allows to type for example "layername[10,10]" which is interpreted by mapcalc as reference for neighbourhood of each processed cell in raster. Now the bug is fixed and nice feature is over. The question is: Is there currently another way in GRASS raster map calculator which allows to use referencies for cells neighbourhood? Is it possible to change static list of GRASS raster layers to be writeable?
