Dear Grass users,
I have a raster map. It contains 720 rows x 960 columns =691200 pixels.
There are 32676 categories. I want to generate the category for each pixel; somewhat in this manner. For one pixel the lat-long bound comes to be a grid of 2 min,15 sec x 2 min, 15 sec. I want the output somewhat like this:
-------------------------------------------------------------------
pixel North lat South lat East long West long category
------ -------- --------- ---------- ---------- --------
1,1 07:02:15N 07:00:00N 68:02:15E 68:00:00E 34
1,2 07:02:15N 07:00:00N 68:04:30E 68:02:15E 21
.. ........ ........ ........ ........ ..
720,960 34:50:15 34:48:00 93:02:00 93:00:00 97
I am trying to first take the first row and traversing all the 960 columns, then taking the second row and traversing through all the 960 column and continuing the process till all the 720 rows and 960 columns are covered. I think we can get a similar output by using g.region and ultimately setting the region of each pixel by its lat long value (perhaps by a loop). Yet I want all the data in the single file unlike generating a separate file for each category. Since creating separate file for each pixel would result in 691200 files....
very difficult to read. Is it possible in GRASS ? Please suggest me some solution.
Thanks in advance.
uttam.
