The min statistic can be swapped out for for a different statistic if desirable but if you are interested in pulling out tracks over a certain height then applying a min statistic during the dissolve will show you the lowest point of that track.</P><P></P><P>hope this helps.</P><P></P><P>Ross</P></BODY></HTML> Fri, 19 Jul 2019 09:13:00 GMT https://community.esri.com/t5/geogeeks-questions/how-do-i-add-elevation-from-a-raster-to-a-polyline/m-p/798561#M25 RossGoodacre1 2019-07-19T09:13:00Z Re: How do I add elevation from a raster to a polyline to extract a track above a certain height? https://community.esri.com/t5/geogeeks-questions/how-do-i-add-elevation-from-a-raster-to-a-polyline/m-p/798562#M26 <HTML><HEAD></HEAD><BODY><P>If you have access to the 3d analyst toolbox, interpolate shape does this.</P><P><A href="http://desktop.arcgis.com/en/arcmap/latest/tools/3d-analyst-toolbox/interpolate-shape.htm">http://desktop.arcgis.com/en/arcmap/latest/tools/3d-analyst-toolbox/interpolate-shape.htm</A></P></BODY></HTML> Fri, 19 Jul 2019 09:24:52 GMT https://community.esri.com/t5/geogeeks-questions/how-do-i-add-elevation-from-a-raster-to-a-polyline/m-p/798562#M26 NeilAyres 2019-07-19T09:24:52Z
