The Geospatial Modelling Environment (GME) is the predecessor of the Hawths Tools extension for ArcGIS, but with some important improvements. It is designed to help to facilitate rigorous spatial analysis and modelling by linking ArcGIS to the statistical software package R. It has a greater range of analysis and modelling tools, supports batch processing, offers new graphing functionality, automatically records work-flows for future reference, supports geodatabases, and can be called programatically.
GME has dependencies on three other software packages (R, StatConn, ArcGIS) and to ensure successful communication between them requires careful version management. The recommended installation strategy is to install/upgrade these dependencies before installing GME. Use the table below to identify versions of the software you wish to acquire. If you are upgrading any of the dependencies, it is recommended that you use Control Panel to uninstall the old version first. See below for further details.
You must have administrator rights to run the installer (in Vista, right-click the installer and select â€˜Run as Administratorâ€™), and you must be connected to the internet.
Use the table below to determine if your version of ArcGIS is supported (note that SP stands for Service Pack). If your version is not listed, it is recommended that you do not install GME.
If your version is supported, run it as an Administrator, and follow the instructions it provides. Note that if you encounter any installation problems the information on the Installation page (see link at top) will help you to resolve them.
