I'm new with qgis and grass so I'm sorry if there is a straightforward answer for this question but I can't seem to get it done. I've imported a pointcloud into qgis from a datafile. Now i'd like to plot these data points into 3D by using grass. First of all, I couldn't import the qgis file...

I'm stuck on how to collapse all layers in my ArcMap projects (9.3). I've tried a few bits of sample code, but they all seem to fail for some reason or other. Some of the layers might be grouped, and some are imagery or WMS layers if that makes a difference. Here is some code I have tinkered...

I'm trying to create a function which calculates the nearest neighbors under a certain length in a table s_1 an stores them in an output table. This is what I've got so far: CREATE OR REPLACE FUNCTION NearestN() RETURNS TABLE ( a integer,b integer,ST_Distance integer)AS $$ SELECT...

I'm pretty new to Model Builder and have been working on a tool that separates a an exotic vegetation point feature class by species, then separates each species by treatment action, and then date. I made a model using Iterate Field Values to create a new output feature class for each...

What is the correct syntax for the geometry object's "intersect" method in ArcPy? I'm building a script that utilizes the intersect method of the geometry class so that I can run an intersect analysis on individual polygons within a feature class. As stated here, "intersect (other, dimension)"...
