Installation

This installation works under the assumption that the user is familiar with the installation and implementation of the SLEUTH model. For basic tutorials and installation, refer to the Project Gigalopolis website. The procedure for installing the SLEUTsH is as follows.

Step 1: Downloading the original SLEUTH source code

The source codes for the SLEUTH models are available here. There are currently two versions listed that vary mainly on how model calibration is done.

The choice of the model will depend on the user. The SLEUTH GA will implement the calibration faster than the second one, which uses brute force calibrations using Monte Carlo simulation.

Step 2: Downloading the patch files to represent SLEUTsH

The source codes of the original SLEUTH have to be updated in order to reflect the growth rules of railway-induced urban growth. The patches to reflect this can be downloaded through the links below.

  • For SLEUTHGA, download the files through the repository here.

  • For the SLEUTH, download the files through the repository here.

Step 3: Replacing the original source codes with the patch

  1. Create a folder where the SLEUTsH is to be installed.

  2. Copy the contents of the original SLEUTH folder (either SLEUTHGA or SLEUTH) into the SLEUTsH folder.

  3. Move the patch files into the SLEUTH folder.

While the patch files are intended to introduce railway-induced urban growth, additional patches are added for efficiency, such as:

  • Increasing the allowed number of input files

  • Removing the years in the predicted images (useful when post-processing the outputs with GIS tools)

  • Increasing the character lengths of files

Step 4: Installing the SLEUTsH model

Inside the SLEUTsH folder, the common procedure used to install all SLEUTH models must be followed. For details, visit the Project Gigalopolis site.
