This tool gives you access to the qGIS version of pythonĬheck pip (a python package manager) is up to date with the following: python -m pip install -upgrade setuptools Right-click on it and select Run as administrator. Open the start menu and search for OSGeo4W Shell. Installing mplstereonet and scikit-image on Windows can be a little tricky, as skimage contains uncompiled c-code. Manual install instructions for MS Windows users If this automatic install doesn't work then the plugin can be installed in by following the manual install instructions below. The other dependencies should be automatically downloaded and installed the first time GeoTrace is run (at least on Windows and Linux). QGis should come bundled with Numpy and Matplotlib. GeoTrace uses Numpy, Matplotlib, mplstereonet and scikit-image. On Linux the plugin can be cloned to any directory and then the relevant files are copied to the correct locations using the by running the command 'make deploy'.Note that you may need to create the plugins folder. On windows, this path will be something like C:/Users/USERNAME/AppData/Roaming/QGIS/QGIS3/profiles/default/python/plugins.Clone (or download and unzip) the GeoTrace directory into your QGIS plugin path.To do this use the plugin manager in QGIS and select experimental plugins. The prefered option is to use the QGIS plugin repository as this will retrieve the most recent stable version of the plugin.A variety ofįunctions for quickly calculating such a cost function have been included in the Cost Calculator tab. Single-channel cost raster in which the structures of interest are represented by low values, and the background by high values. The trace extraction method ( Trace tab) uses a least-cost path algorithm to 'follow' linear features in the raster. The results on stereonets and rose diagrams. It canīe used to rapidly digitize structural traces in raster data, estimate their 3D orientations using an associated DEM, and then visualise GeoTrace is a a QGIS plugin containing some helpful tools for extracting and analysing the orientations of geological structures.
