      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;SPAN&gt;Hola Elías,&lt;/SPAN&gt;&lt;BR /&gt;&lt;BR /&gt;&lt;SPAN&gt;Creo que usted identificar el problema clave que algunas capas no se le había asignado la proyección. &lt;/SPAN&gt;&lt;BR /&gt;&lt;BR /&gt;&lt;SPAN&gt;También es importante que utilice un sistema de coordenadas proyectadas, como WGS84 UTM Norte 16, de modo que el área se calcula correctamente y luego pueden ser procesados �??�??utilizando GeoHMS.&lt;/SPAN&gt;&lt;BR /&gt;&lt;BR /&gt;&lt;SPAN&gt;Las nuevas versiones de GeoHMS corregir algunos problemas con el procesamiento de la cuenca. Por lo tanto, mantener la instalación de ArcHydro e instalación de GeoHMS el más reciente.&lt;/SPAN&gt;&lt;BR /&gt;&lt;BR /&gt;&lt;SPAN&gt;Stuart&lt;/SPAN&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
