Asunto: [GRASS-user] r.reclass null values
<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
r.null map=yourmap null=6
