With QGIS 3.2.3., I’m trying to create a heatmap of a set of events (ie: bikes passing on a road). This is the original vector.
What I’m trying to get is a heatmap with darker colour where a lot of bikes have passed, and light colour where a few have.
I’ve tried two approaces:
1) Gdal > Vector Conversion > Rasterize
2) Interpolation > Heatmap (Kernel Density)
I’ve tried with several parameters, but I always get, a result which is not satisfactory:
1) I get a single pixel where I had an event (so just 0/1 resolution)
2) I get very large circles, going out of my scope
(I attach here two examples).
Can anybody help me to set the right parameters?
