I have a number of points on a map, each with a numeric attribute taking values from 1-9. The points with attribute equal 1 should have the highest density representation, and the points with attribute equal to 9 should have the lowest.
Heat maps in QGIS rely on the density of points in an area having a higher density, but I am trying to calculate it based on that numeric attribute, even if the points are further apart.
I tried using IDW interpolation and TIN interpolation (with distance coefficient = 1), but both produced a black layer as output. I was expecting to see 9 different colors scattered across the map instead. Is there another way to represent what I want?
I'm essentially assigning point vertices representing streets values from 1-9, 1 being the most suitable to walk, and 9 being the most unsafe. I'm just trying to visually show those results on the map.
