<div dir="ltr">Hi<br><div class="gmail_extra"><br><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Thanks, Vero<br>
unfortunately I don't know how to create colormap rules file without GUI which is not working...<br>
<br></blockquote><div>Do you know the range of values your map takes, right?? So, let's say it goes from 0 to 100, just split values as you wish and assign colors, it will consider those intervals. Example:</div><div><br></div><div>0 black</div><div>20 yellow</div><div>40 orange</div><div>60 red</div><div>80 green</div><div>100 blue</div><div><br></div><div>There are a lot of examples here: <a href="http://grass.osgeo.org/grass71/manuals/r.colors.html">http://grass.osgeo.org/grass71/manuals/r.colors.html</a></div><div> <br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
And by the way, I need to change break values rather than apply certain colors to make maps visually comparble. Maybe there is a way to do it with command line?</blockquote><div> </div><div>you set the color table for one map (map1), and then, to make them visually comparable, you set the other maps color table to the first map, like this:</div><div><br></div><div>r.colors map=map2,map3,map4 raster=map1 </div><div><br></div><div>so, all maps will take the color table of map1.</div><div><br></div><div>Cheers, </div><div>Vero</div><div><br></div></div></div></div>
