I need to create a sector grid radiating out from a point of interest. Here is an example that I laboriously put together by hand:
I have found a couple of similar solutions in How to generate dartboard shapefiles using ArcGIS for Desktop? and Draw wind rose with QGIS from PostGIS but neither exactly fit my criteria.
Ideally I need each sector to be an individual polygon (for data analysis purposes) and to be able to create this overlay for different sites using parameters to control the number of sectors and radial distances.
Can anyone suggest or provide a means to generate these shapes in QGIS easily? I rather presume that this is a relatively common task so don’t want to go to great effort to reinvent the wheel but I am struggling to find a solution and being a complete newcomer it would take me a very long time to come up with a solution from scratch.
