In ArcMap use the Identify tool and point at cells (pixels) in the raster. It should give you 2 or more values, among them "Stretched" and "Pixel value". Stretched is the colour/brightness, and changes according to Symbology settings. Pixel value is the raw value, and in the case of a DEM will be your Elevation or Z value. Use an area well above sea level ...


Hillshade raster is a 2D representation of the surface created from the DEM (3D) input. In order to display the hillshade as a "3D" surface, you will need to draped it onto the source DEM (or any other surface that has XYZ values, it could be DEM, TIN, or Terrain) In fact even when you just add a DEM into ArcScene it will initially display flat unless you ...

Under the Base Heights tab, select the "Floating on a custom surface" radio button, and navigate to your DEM if it is not already populated in the browse box. Hit Apply and OK. ArcScene will render the ...

Google Earth for Android can be programmatically accessed through Intents. This way you can open a KML in Google Earth or send a location and a zoom level to Google Earth.


I just implemented this myself and posted my answer over on StackOverflow, but I figured I'd drop my version here for others to view: import numpy as np from scipy.spatial import ConvexHull def minimum_bounding_rectangle(points): """ Find the smallest bounding rectangle for a set of points. Returns a set of points representing the corners of ...
