- Double-click on the file "spacenet_2-5r2.jar" to launch the application.
SpaceNet 2.5 (Java) Executable - v2.5.1075 (.zip, 7.83 MB)
SpaceNet 2.5 is an updated version of SpaceNet migrated to a Java environment. It should be considered is research-grade code. As such, it has not received exhaustive testing during development. Though every available effort has been expended to eliminate bugs, there is a good chance that residual errors will inevitably occur.
Please make full use of the user community, as only limited support will be available from the developers. A SpaceNet community has been established hosted by Google groups.
SpaceNet 2.5 is released under a GNU General Public License (GPL). As such, the source code is also available here: v2.5.1075 Source (.zip, 7.5 MB)
To run SpaceNet 2.5, follow these steps:
- Download the compressed file spacenet_2-5.1075_jar.zip
- Unzip the downloaded file to create the folder spacenet_2-5.1075_jar
- Double-click on the file "spacenet_2-5.jar" to launch the application.
SpaceNet 1.3 (MATLAB) - v1.3 (.zip, 17.91 MB)
SpaceNet 1.3 is the first publicly available distribution. It runs within MATLAB, which must be installed on your system to work properly, and uses Excel spreadsheets to store numerical models and data. Also, the publicly-available distribution does not include the optimization module, so if you attempt to use it, the program will error out.
To run SpaceNet 1.3, follow these steps:
- Download the compressed file spacenet_1-3.zip
- Upzip the downloaded file to create the folder spacenet_1-3
- Launch MATLAB and change your working directory to:
spacenet_1-3/gui
- Run the MATLAB command:
SpaceNet
Additional documentation, including the User Guide and Quick Start Tutorial, is available within the spacenet_1-3/docs directory.
