I want to show the density of these attributes and then demonstrate a threshold (no. of attributes) in hot spots in each heritage site. </div><div><br></div><div>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? Depending on attribute, I set the radius to 10m, 5m and 1m.</div><div><br></div><div>This is for my PhD, so I need the mapping and hot spot math to be accurate rather than representative.</div><div><br></div><div>Any advice on this will be much appreciated,</div><div><br></div><div>Julia</div><div><br></div><div><br></div><div data-signatureblock="true"><div>Sent from Windows Mail</div><div><br></div></div></div>
