Gate Transformer is a plugin to modify the geometry of gates used in space syntax movement observations. Gates are usually drawn perpendicular to the axial line, with varying lengths. For presentation of movement observations the typical output is a map showing lines along the axial lines to indicate the movement direction. The gates should all be rotated 90degrees and have the same length.
Currently the plugin is not available through the QGIS plugins repository. To install you need to download the latest GateTransformer_private_0.0.1B.zip file from the releases page (https://github.com/OpenDigitalWorks/GateTransformer/releases). Unzip and copy the entire folder into the QGIS plugins directory.
This directory can be found here:
- MS Windows: C:\Users[your user name].qgis2\python\plugins\
- Mac OSX: Users/[your user name]/.qgis2/python/plugins/
- Linux: home/[your user name]/.qgis2/python/plugins/
This directory is usually hidden and you must make hidden files visible. Under Mac OSX you can open the folder in Finder by selecting 'Go > Go To Folder...' and typing '~/.qgis2/python/plugins/'. If you haven’t installed any QGIS plugins so far, you need to create the ‘plugins’ directory in the ‘.qgis2/python/’ directory. After copying the plugin, it will be available in the plugin manager window once you (re)start QGIS. Check the box next to the plugin to load it.
