&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;== Líneas de contorno a partir de un MDE ==&lt;br /&gt;
&lt;br /&gt;
La extracción de isolíneas (contornos, en el caso de una superficie de elevación), se puede derivar de datos ráster usando el módulo {{cmd|r.contour}}.De manera predeterminada, el módulo determina el valor máximo y mínimo de las isolíneas para un mapa ráster dado. El intervalo de isolínea/contorno debe ser definido con el parámetro &amp;quot;step&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
Ejemplo: generar contornos con un intervalo de 10m a partir del mapa ráster &amp;quot;elevation&amp;quot; (conjunto de datos de muestra de [http://grass.osgeo.org/download/sample-data/ North Carolina]):&lt;br /&gt;
&lt;br /&gt;
&amp;lt;source lang=&amp;quot;bash&amp;quot;&amp;gt;&lt;br /&gt;
# Establecer la región computacional:&lt;br /&gt;
g.region rast=elevation -p&lt;br /&gt;
&lt;br /&gt;
r.contour elevation out=elev_contour_10m step=10&lt;br /&gt;
&lt;br /&gt;
# visualizar&lt;br /&gt;
d.mon x0&lt;br /&gt;
d.erase&lt;br /&gt;
d.rast elevation&lt;br /&gt;
d.vect elev_contour_10m&lt;br /&gt;
d.barscale -mt&lt;br /&gt;
&amp;lt;/source&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Las líneas de contorno resultantes están guardadas en un mapa vectorial llamado &amp;quot;elev_contour_10m&amp;quot;.&lt;br /&gt;
