We are developing a property look up tool for environmental hazards/chemical spills. In layout view we have a circular data extent with a graphic of a target house in the center and some proportional circles at increments of .125, .25, .5 and 1 miles from the center of the fixed extent. My...

I am working with a watershed map, and I was wondering if there is a function or a way that I can get ArcMap to number the watersheds. For instance, if we have watershed X numbered as 0, I want the watersheds that surround/or share a boundary with watershed X to be numbered 1, and the watersheds...

As far as I understand the EGM96 defines the Geoid, where as the WGS84 Standard defines the Ellipsoid. Is the ellipsoid defined in the WGS84 standard defined in a way to maximize the congruency with the the geoid defined in the EGM96 standard? أكثر...

How can I quickly check to see if a polygon(or whatever) intersects anything in a massive table? I'm trying to find polygons that don't intersect with the North American street network at any point. Most of my polygons do intersect. My street network (a routeable edge table) has almost 50...

My script takes separate 3D feature classes, calculates a field, appends to a target feature class, and then deletes the originals. This is a huge data processing task of over 4700 mass point feature classes appending to a single one. I know it was a big mistake to put so many feature classes...
