Consultar poblaciones a las que no le llega una vía de comunicación con Geomedia

Si tenemos una base de datos geográfica que contiene diferentes clases de entidad de poblaciones (ya sean tipo área o tipo punto) y además contamos con varias clases de entidad de vías de comunicaciones (lineales) es sencillo con Geomedia y mediante una serie de consultas, obtener las poblaciones que están aisladas, sin vía de comunicación que llegue a ella, o bien con vía que le llega pero no conecta correctamente

Esta operación de control es muy útil en proyectos cartográficos y de SIG  y será una comprobación que haya que realizar en casi todo proyecto, por su carácter general

El proceso sería el siguiente:

  1. En primer lugar, si se cuenta con más de una tabla (clase de entidad) de poblaciones tipo área, poblaciones tipo punto y vías de comunicación tipo línea, será preciso unirlas en una única consulta, por el tipo de geometría. Esto se realiza en Geomedia en el menú Análisis> Unión. Se eligen las clases de entidad que se desean unir en cada consulta y se nombra cada una de ellas. En este caso se tendrían tres consultas de unión, una para las poblaciones de área, otra para las poblaciones de línea y otra para las vías de comunicación.curso-de-cartografia
  2. Después por cada consulta de unión de poblaciones se hará una nueva consulta en el menú Análisis> Consulta Espacial. Como primera entidad se seleccionará la unión de poblaciones (por ejemplo Unión_poblaciones_area) y se seleccionará la operación NOT TOUCH. En la clase de entidad siguiente se seleccionará la unión de las vías de comunicación (por ejemplo Unión_vias). Esta operación significa: “selecciona todas las entidades de área de poblaciones que no son tocadas por ninguna de las vías tipo línea”.curso-de-cartografia
  3. El resultado es una consulta en la que se recogerán todas las entidades de población a las que no llega vía de comunicación (en la imagen señaladas en azul), o que llegando, no está bien conectada a un vértice o nodo de la población correctamente.
  4. Según se va corrigiendo cada uno de los errores, este se va eliminando automáticamente de la consulta, de modo que la corrección de errores resulta muy sencilla.

    our stuckness. Many women pick the ankle initially due to the fact

    Justin Thomas. One of the more underrated quarterbacks in the ACC - partly because of the other quarterbacks at the top of the league, and yes, partly because the Georgia Tech offense isn鈥檛 given enough due 鈥?he hopefully turned some heads in the ACC title game with his performance. He finished with a whopping 9.5 yards per rush (134 total yards on the ground) and 8-of-14 passing for 13 yards, one touchdown and one interception (9.6 per pass attempt). He鈥檚 going to have to be that special and then some in this game, because as we saw down the stretch, life without wide receiver DeAndre Smelter when playing from behind is not easy. Georgia Tech didn鈥檛 even have to throw the football for awhile, and as good as Thomas was, it鈥檚 just hard being down one of your best weapons in the passing game. But Georgia Tech has had time to figure it out (they didn鈥檛 in the ACC title game), and maybe someone else will emerge.
