ArcTutorials - GIS screencasts and tutorials.

Extending ArcGIS can be done with many programming languages, but we will focus specifically on Visual Basic for Applications (VBA) because it is the most widely used currently.

Extracting values to points is very useful when you need to get data from a raster at a specific point. A very common case is when your raster is based on elevation values, such as a DEM, and you have a points layer that might represent survey stations or something similar. This tool takes the elevation values and puts them into that point layer. Watch the screencast to see how.
