The best way to exclude areas from raster processing in ArcGIS is with the Mask Environment Setting. To use it, you will need a positive mask that covers the areas that you want to process, rather than a negative mask that covers the areas that you want to exclude. To create a positive mask, draw a really big polygon and clip it with the features covering ...

There are several ways to accomplish what you want. You've left out some specifics such as what extensions you have available and what license level you're using, as well as how thoroughly you want to sample the raster (ie how fine is your grid). I'll make some assumptions. The simplest, if you want a point for every cell in the DEM, is the Raster to Point ...

Short answer, use the DEM. Handheld GPS units of the type you mention (consumer grade), can potentially use two different methods to figure elevation - the calculated GPS position or an internal barometric altimeter. Because of the way GPS works (explained at the page mkennedy originally linked to in a comment, and elsewhere), without high-grade, corrected ...

From the help: Mask—A dataset that defines which locations in the inputs will be considered in the execution of the tool. If the mask dataset is a raster, all cells with a value will compose the mask. Cells that are NoData in a raster mask will be NoData in the output. If a feature dataset is used as input for the mask, it will be converted internally to a ...

Indeed, the results of a single-geometry InSAR analysis yield Line of Sight deformations. When using a double geometry (both imagery in acscending and descending directions) the vertical component can be computed. The horizontal deformation measurement is in that case sensitive in the East-West direction en far less sensitive in the North-South direction ...

I would suggest what Stella said below. You can simply classify it as shadow so it doesn't hurt your accuracy. Of course make sure you have enough areas of interest or training areas of the shadow to make sure that it is all classified. If you have to give a presentation, you can comment that most of the shadow areas are uniform with the near side part of ...

An answer in another thread pointed to a software that seems to be what I'm looking for. It's called Leveller and is made by Canadian company called Daylon Graphics. The software is paid and sadly has no trial version. http://www.daylongraphics.com/products/leveller.php
