Re: [GRASS-user] Understanding Raster Map Input Files
Hi Vidura, Just like Moritz said, you need to start by the basics about GRASS. That said, it is better to create new raster layers than change the existing ones. To test other wind speed and direction, moisture, etc, just create new rasters with r.mapcalc https://grass.osgeo.org/grass74/manuals/r.mapcalc.html Start with constant rasters, using the example in the r.mapcalc manual.

GRASS GIS is an extremely wonderful and powerful tool, but it does need some initial learning in order to understand how to use it. Just answering the questions below will not provide that for you. I would suggest that you go through some of the basic introductory material, just in order to get a feeling for GRASS GIS, before attacking your specific problem. You could have a look at the following resources (at least for their introductory parts): - https://grass.osgeo.org/grass74/manuals/helptext.html - https://grass.osgeo.org/grass74/manuals/rasterintro.html - https://grass.osgeo.org/grass74/manuals/vectorintro.html - https://grasswiki.osgeo.org/wiki/From_GRASS_GIS_novice_to_power_user_(workshop_at_FOSS4G_Boston_2017) - http://www.training.gismentors.eu/isprs-summer-school-2016/lesson1/grass-gis.html Or search for "GRASS GIS" in YouTube for some videos. > Let's say I need to create custom > 1hour_moisture (or any other file), so how can I create these files? How you create these files depends on the data that you have as input. If you look at the metadata of the file in the demolocation (right-click->Metadata or 'r.info 1hour_moisture' you will this information at the end: | Data Description: | |generated by r.mapcalc | | | | Comments: | |if(fuel_class==4,3
