Hi, I want to use r.cost to calculate accessibility surfaces based on an existing road network. In my cost surface, I want to associate a speed limit = 6kmh to every cell outside the network, which involves reclassifying all NULL values to 6. However. <r.reclass> doesn't allow me to reclass the nulls. The following message appears:
WARNING: can't have null on the left-hand side of the rule illegal reclass rule. ignored Any clues on how to do this? I couldn't find any offer function which would do the trick. Apologize if this is a "too simple" kind of question... Thanks in advance, António
