DescriptionGlasgow park access network (8520851663).png
Map showing distance from parks in Glasgow. Dark red equals further away from park. Distance is calculated from park entrances indicated by black points. This is a rough hack to demonstrate the possibilities of openstreetmap data and GRASS/qgis network analysis. This was inspired by this GRASS tutorial: <a href="http://jcastellssala.wordpress.com/2012/05/07/basic-network-analysis-with-grass/" rel="noreferrer nofollow">jcastellssala.wordpress.com/2012/05/07/basic-network-anal...</a>
I used QGIS's GRASS gui and shell. Park entrance points were produced by making the park polygons into line vectors and then intersecting with highway network (including footpaths etc). I used QGIS vector analysis and geometry tools to achieve this.
Next project will look at pubs...
