PolygonZ to Raster

IraklisKarampourniotis — Fri, 13 Jan 2012 18:49:49 GMT

Hi again,

I have a shp file with PolygonZ and I want to convert each of these (polygonZ) into rasters.

Any idea how?

Iraklis,

There is a geo-processing tool called Polygon to Raster and its found in the Conversion > To Raster toolbox.

Hi Duncan,

Sorry but Polygon to Raster wont work because it only make the raster single value and my polygon has a slope so I need a raster that has different values per pixel relevant to the elevation (z value) of the polygon.

Thanks.

Are you saying the vertices of the polygon contain z values? You could convert your polygon to points with z values then convert these to pixels with their z values.

Yes the vertices have z values (Shape.Z).
Feature to Point returns only one point per feature (per polygon) so it doesn't provide the result I need.

Thanks though!
Any other suggestion?

Could try the tool feature vertices to points? http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/Feature_Vertices_To_Points/00170000003p000000/
