topic Slope calculation in 3D Questions https://community.esri.com/t5/3d-questions/slope-calculation/m-p/221795#M1355 <HTML><HEAD></HEAD><BODY><SPAN>Hello</SPAN><BR /><BR /><SPAN>I'm new to ArcGIS but I study hard to learn. Well, I have a problem. I've created a TIN surface from contours. I want to calculate the slope in degrees and percentage. I have converted the TIN surface to Raster data. Then, in ArcCatalog in toolbox, from 3D Analyst - &gt; Raster Surface - &gt; Slope.</SPAN><BR /><BR /><SPAN>The question is... Why when I convert the TIN to Raster with 10.89 cell size, the slope calculation is working. But when I convert the TIN to raster with, for example 1 or less cell size, the Slope calculation won't work. It showes me values like: "3.4135+E0..". </SPAN><BR /><BR /><SPAN>And are any ways to calculate the slope? The next thing I have to do, is to create a path or a road with the slope values. Is there any way to correlate them in model builder?</SPAN><BR /><BR /><SPAN>Thanks</SPAN><BR /><BR /><SPAN>Have a nice day</SPAN></BODY></HTML> Sun, 15 Jan 2012 13:05:58 GMT Andrei_SebastianSasu 2012-01-15T13:05:58Z Slope calculation https://community.esri.com/t5/3d-questions/slope-calculation/m-p/221795#M1355 <HTML><HEAD></HEAD><BODY><SPAN>Hello</SPAN><BR /><BR /><SPAN>I'm new to ArcGIS but I study hard to learn.
