Thank you very much. It is much easy to understand the kernel function options now. Thanks once again. On Fri, Dec 4, 2015 at 1:44 PM, Glynn Clements wrote: > > Uttam Kumar wrote: > > > 4.) Which one of the above GRASS commands would be best suited to perform > > window

[GRASS-user] Do filters available in GRASS takes care of cell padding?

Hi, Do the filters available in GRASS GIS such as average, low pass, high pass filters take care of cell padding automatically? By Cell paddding, I refer to duplicating the first row on top, duplicating bottom row at the bottom, duplicating first column before the actual first column and duplicat

Re: [GRASS-user] i.cluster/i.maxlik question

As I understand GRASS can handle both conditions (i.e. the number of clusters (through the parameter classes) and "iterations" as the criteria to converge. The algorithm will stop as soon as any of the conditions are met first. https://grass.osgeo.org/grass64/manuals/i.cluster.html On Thu, Nov 26

[GRASS-user] Need help in r.lake

Hello All, I have a raster map with several lakes. Each lake is filled with some water which I treat as a seed pixel. I want these lake to be filled with water until they reach the top that is there is no more increase in elevation. I can use r.lake but it accepts only one value for water level p

[GRASS-user] Is Watershed image segmentation program in GRASS GIS?

Hi All, Is watershed image segmentation program or a similar module available in GRASS GIS? I understand that we have r.watershed, i.segment and r.grow in GRASS GIS. But I do not know which one best suits my problem. The problem is: I have two layers of raster data - 1.) a gradient image (obtai

Thank you all for the suggestions. I could resolve the problem. GRASS gives me same projected coordinates as ENVI. On Fri, Oct 23, 2015 at 12:46 AM, Markus Neteler wrote: > > On Oct 23, 2015 2:22 AM, "Uttam Kumar" wrote: > > ... > > GRASS 7.1.svn (SanLuis_R

Re: [GRASS-user] Need help in reprojecting raster images

Thank you all. It worked. However I noticed that the projected boundary values of N, S, W and E in GRASS are not same as the values obtained from projecting the same image in ENVI image processing software and in gdalwarp. Projection of the scene in Lambert Azimuthal Equal Area is similar (but no
