I am mapping 5 heritage sites using DGPS point data. Each site has 100s, and in two cases 1000s, of points representing various attributes. I want to show the density of attributes and then demonstrate a threshold (no. of attributes) in hot spots for each heritage site.
I have no problems creating heat and hot spot maps following the QGIS instruction manual and Ujaval Gandhi’s tutorials, but I am uncertain about how to use the advanced raster heatmap plugin settings to set the x and y cell size, kernel shape etc. I seem to get different results every time I create a map. So, is it ok to leave the advanced settings off? and just choose the radius? I set the radius to 10m, 5m and 1m depending on the attribute I want to display.
I need the heat mapping to be representative and the hot spot mapping to be accurate.
