Fill space between polygons

JoostBrama — Mon, 02 Jun 2014 11:41:18 GMT

Hi,

I'm trying to fill space between different features in a feature class.
It is a feature class with streets as polygons, and every street has a streetname as attribute value.

What I want is to fill up al the empty spaces in an specified region.
All these empty spaces need to get the streetname of the nearest street.

Hi,

Don't know if this helps at all? http://gis.stackexchange.com/questions/53414/creating-thiessen-voronoi-polygons-using-lines-rather-than-points-as-the-inp

Thiessen or Voronoi polygons allow you to create polygons from point features where every point within each polygon is nearer to a certain point than any of the others. You want to do this with lines (or are your road features polygons?)

I'm not sure exactly how you'd do it, but the link above has some hints. It suggests that it may be easier using a raster representation...

Hope that helps

Dan

You need ET Geowizard's tools to do it as shown on this page. It requires a point on the line very close to the intersection, but slightly offset on each line in addition to any point directly on the intersection.
