Basically i have lead test results in points data set and i am using the level of lead as field to calculate hot spots. after that i end up with points data layer with p-values and z-values. Then i tried using kernel and point density to calculate the surface but is that the right way? I need this as a heat map layer under testing locations so that high lead results areas can be targeted for more testing.</P><P>Thanks!</P><P>Nikki</P></BODY></HTML> Wed, 28 Mar 2018 13:15:48 GMT https://community.esri.com/t5/arcgis-spatial-analyst-questions/how-to-convert-hot-spot-points-to-surface-kernel/m-p/79659#M1123 NavjotKaur 2018-03-28T13:15:48Z Re: how to convert hot spot points to surface? kernel density? https://community.esri.com/t5/arcgis-spatial-analyst-questions/how-to-convert-hot-spot-points-to-surface-kernel/m-p/79660#M1124 <HTML><HEAD></HEAD><BODY><P>You can create a continuous surface by interpolating on the Z-values using an interpolator like <EM>Natural Neighbor</EM> or <EM>IDW</EM>.&nbsp;</P></BODY></HTML> Wed, 28 Mar 2018 15:35:48 GMT https://community.esri.com/t5/arcgis-spatial-analyst-questions/how-to-convert-hot-spot-points-to-surface-kernel/m-p/79660#M1124 MervynLotter 2018-03-28T15:35:48Z
