I'm currently working on a project in which I need to build a topological network out of the geometry features I find in shapefiles. So far using Ben Reilly's open source project I've managed to ...
This question is more related to resources that I might not have identified yet, although I've been searching the web for a while. In the project I'm working at the moment I need to run a ...
using Gdal/ OGR is there a way to convert a shp, kml, or PostGIS line layer into a network of nodes and segments so it can be used in packages such as networkx?
I am trying to calculate shortest path between 2 points using Dijkstra and A Star algorithms (in a directed NetworkX graph). At the moment it works fine and I can see the calculated path but I would ...
I want to perform shortest-path analysis on a network whose edges represent real-world roads and whose nodes are buildings or other locations. I have the shapefile for the area I'm interested in. ...
I want to use a slope-raster for a a_star path analysis in NetworkX. I am using Python for this project. My test raster looks like this First I read in the raster with GDAL input_raster = ...
I tried to use the Python module networkx and specifically the read-shp () to ensure the transformation of a graph to a file sharpe but I always find this error noting that this is the first time I ...
How to install and how to compile networkx python on QGIS? I always get an error that no module named networkx in the console of QGIS I copied the file networkx in C:\Program Files\Quantum GIS ...
Note that although I am using Python Console from within QGIS for this, I don't think it's a QGIS issue. Below is the difference of how NetworkX is dealing with 2 line layers created by the same ...
