[Gvsig_usuarios] error en Thiessen/Voronoi

[Carlos Almeida]

Hola a todos.

Sigo testando lo gvSIG 1.10 RC2

Em geoproceso de Tiessen/Voronoi (generar triangulos), sienpre es uma "luta"
a hacer funcionar.

Tengo atachado, lo archivo de puntos, para generar el poligonos.
Pelo error, es porque gvSIG no acepta puntos con esta formatacion. Pero,
gvSIG hace muy restrictivo para hacer algunas tarefas, como esta.

Lo error esta en la mesage.

Gracias. Carlos Almeida
