topic Using ArcCatalog's New Terrain Tool vs. ArcToolbox Terrain Tools in Model in 3D Questions https://community.esri.com/t5/3d-questions/using-arccatalog-s-new-terrain-tool-vs-arctoolbox/m-p/673223#M4020 <HTML><HEAD></HEAD><BODY><SPAN>I have a problem making a terrain in a model. The results are poor - things are generalized and there apprears to be noise in the terrain. When I make a terrain in ArcCatalog, using the same source data, using the New Terrain tool, the results are good. Why can't I make the same terrain in a model and get good results? I am thinking I have some settings wrong in the model. </SPAN><BR /><BR /><SPAN>Manually, using the New Terrain tool, I set the point spacing to 3 ft, I select Z Tolerance, and I add 7 levels of pyramids: 1000, 2000, 5000, 10000, 25000, 50000 and 100000. With these settings in the New Terrain tool I get a usable terrain. I try to approximate the same settings in my model but I have problems. My model uses the Create Terrain, Add Terrain Pyramid Level, Add Feature Class to Terrain and Build Terrain tools, in that order. I set the Average Point (Create Terrain) to 3. It does not seem to make a difference if I set a Pyramid Type parameter (for ZTolerance). In the Add Terrain Pyramid Level tool, I set the Pyramid Levels Definition values as 0.5 1000, 1 2000, 1 5000, 2 10000, 4 25000 8 50000 16 100000. I think these seetings in the model are an approximation of the settings when I manually make a terrain with the New Terrain tool, but I keep getting poor results with the model.</SPAN><BR /><BR /><SPAN>Could someone suggest things I could try to make a good terrain in my model? I must be missing something. Thanks!</SPAN></BODY></HTML> Wed, 13 Jul 2011 17:25:55 GMT JacobCoble 2011-07-13T17:25:55Z Using ArcCatalog's New Terrain Tool vs. ArcToolbox Terrain Tools in Model https://community.esri.com/t5/3d-questions/using-arccatalog-s-new-terrain-tool-vs-arctoolbox/m-p/673223#M4020 <HTML><HEAD></HEAD><BODY><SPAN>I have a problem making a terrain in a model.
