<p><font size="2"><Hi,<br>
<br><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:<br>
<br><WARNING: can't have null on the left-hand side of the rule<br>
<illegal reclass rule. ignored<br>
<br>
<Any clues on how to do this? I couldn't find any offer function which would do the trick.<br>
<br><Apologize if this is a "too simple" kind of question...<br><Thanks in advance,<br><António</font></p><p><br></p><pre>r.null map=yourmap null=6<br><br>JM Garijo<br></pre><p><br></p><p><br></p><p><font size="2"><br></font>
