So i have buffered the power lines (all dissolved). That's good,&nbsp; but now im asked to give a slope at each power line, what is the best method to do this. im using NAD_1983_UTM_Zone_11N, Geographic Coordinate System: GCS_North_American_1983, units are meters. When i slope the buffer zone the values area almost one color. Range of the 9 classes are 0-454</P></BODY></HTML> Mon, 27 Jun 2016 21:40:30 GMT https://community.esri.com/t5/spatial-data-science-questions/best-method-to-find-slope-of-power-lines/m-p/167200#M434 MarinaMeter 2016-06-27T21:40:30Z Re: best method to find slope of power lines https://community.esri.com/t5/spatial-data-science-questions/best-method-to-find-slope-of-power-lines/m-p/167201#M435 <HTML><HEAD></HEAD><BODY><P>What is the question here? <IMG src="https://community.esri.com/legacyfs/online/emoticons/happy.png" /></P><P></P><P>In other words, what's wrong with your current result?</P></BODY></HTML> Mon, 27 Jun 2016 21:48:05 GMT https://community.esri.com/t5/spatial-data-science-questions/best-method-to-find-slope-of-power-lines/m-p/167201#M435 DarrenWiens2 2016-06-27T21:48:05Z Re: best method to find slope of power lines https://community.esri.com/t5/spatial-data-science-questions/best-method-to-find-slope-of-power-lines/m-p/167202#M436 <HTML><HEAD></HEAD><BODY><P>Sorry, I know there are many ways, so maybe asking the BEST is a loaded question.
