Subject: Diferencias geométricas entre líneas - by: nramire1 http://geotux.tuxfamily.org/index.php/es/forum/8-bases-de-datos-espaciales/1237#1237 http://geotux.tuxfamily.org/index.php/es/forum/8-bases-de-datos-espaciales/1237#1237 Tengo dos tablas con geometría de líneas la tabla forestal_ln con sus respectivos datos y la tabla mineral_ln con sus datos.
¿Como puedo obtener una tercer tabla con las líneas que se encuentran en la tabla mineral_ln y no están en la tabla forestal_ln?
Abajo dejo los datos con los cuales estoy trabajando.

Subject: ¿Alguna herramienta que acumule el valor de píxeles? - by: adrianfdez57 http://geotux.tuxfamily.org/index.php/es/forum/3-dudas-geo-software/1223#1223 http://geotux.tuxfamily.org/index.php/es/forum/3-dudas-geo-software/1223#1223 Hace unos meses preguntaba por ideas para poder realizar un modelo de desplazamiento de una persona con SIG. Este modelo simula el desplazamiento de una persona por un terreno con unos costes determinados como la pendiente, la vegetación etc etc. Pues bien, ya creo tenerlo casi completo. He conseguido con varios métodos realizar una capa final en el que cada píxel tiene un valor del tiempo en segundos que se tarda en cruzar xada píxel.
¿Sabeis si existe alguna herramienta en ArcGis (y en GvSig a ser posible) que acumule estos píxeles desde un punto hasta un máximo de tiempo? Me explico:
En el modelo habría un punto de partida por ejemplo en formato shp. Desde este punto de partida, la herramienta debería acumular los píxeles hasta los 3600 segundos (por ejemplo), para así simular el desplazamiento de esa persona en una hora. El resultado tendría que ser un "círculo" o isocrona, que represente la zona hasta la que se cumple esa acumulación de 3600 segundos.
¿Alguna idea de cómo realizarlo con Gvsig? ¿y con Arcgis?

Gracias!]]>
