i have a raster file containing information about the windspeed average for the year. My purpose is to reclassify the 15 classes based on their rgb-composite. The color is the only information given. So i want something like this. A is my inputraster.
A.1 == 255 && A.2 == 175 && A.3 == 176 = 1
And that i want to do with all different rgb-composite. Any suggestions? I tried r.reclass r.recode and the mapcalc from QGis.
Thx for your help.
I'am still struggling with this issue. It seems like there is a erorr that has nothing to do with the mapcalc syntax. I just tried a easy expression, like "A*100". I get the following error:
Problem loading output layer:
Oooops! The following output layers could not be open Output raster layer: H:/reclassify/test2.tif The above files could not be opened, which probably indicates that they were not correctly produced by the executed algorithm Checking the log information might help you see why those layers were not created as expected This algorithm requires GRASS to be run. A test to check if GRASS is correctly installed and configured in your system has been performed, with the following result: GRASS seems to be correctly installed and configured
I want to look at the log tab from the algorithm, but when the error appears i can't get access to the log tab. I only can close the error message and after that the r.mapcalc windows are closed too. So i'am not able to mark any lines from the log tab. I really need help.
