There are two parts to Terrest: the code itself and the GUI written by Seth, which makes it easier to edit the parameters. These are located on the DEM svn at svn:dem.cs.umass.edu in folders Winrock and WinrockFE. Right click on the desktop and go to the SVN browser: * You need to check both of these out of the repository but into separate locations - each folder contains a file named setup.py, which is a collection of python compilation instructions. After you have a copy of these on your drive, you need to compile the contents by running the command python setup.py py2exe on each of the setup.py files: * Launch a command prompt, navigate to one of the directories containing the source code and run the python setup.py py2exe command * If everything compiles without trouble (and it should, provided that you have the necessary python prerequisites and windows DLLs installed), you will see two new directories: build and dist. The dist directory will contain the compiled code and the main executable for Terrest, TerrestDEM.exe * When you repeat the compilation process for the front end, you will see a dist directory again containing the main executable WinrockFE.exe * If you run WinrockFE.exe, you'll see the GUI for Terrest, where you can change parameters: * You will need to point the GUI to the correct directories for images / work and image / triangulation report files. Once that is done, and you want to run Terrest, the program will ask you about the location of TerrestDEM.exe**, which is the file that we compiled above.
