I'm working in QGIS right now to create a grid of points within ~36 irregularly shaped polygons. The spacing on the of the points within in the polygons needs to be 3.8/4km.
I attempted using Vector -> Research Tools -> Vector Grid to create an evenly spaced point grid within the polygons but even on the larger polygons that are 30-40 km^2 the tool only creates one point in the very top left corner of the bounding box. Once I create these grid points I'll be exporting them out to KML or XML for use by a 3rd party program that doesn't support shp. The grid will create a "tiling" effect for spot images over an area for our third party software.
I've looked at several of the stack exchange discussions here and none seem to get it quite where I need it.
I was considering creating a 4km fishnet grid over the entire extent (semi-global) and then clipping it to the polygons, then creating centroids for those remaining polygons to produce my grid.
I looked at:
And those have somewhat led me to using the fishnet/centroid solution. I'm wondering if there is a more practical, scriptable way to do this. I'm new to use python in general but am making myself learn it for obvious reasons!
