I used the �??Interpolate Shape�?� tool (3D Analyst) to generate a 3D polyline, where is possible to see the topographic profile of each road segment.</SPAN><BR /><BR /><SPAN>I need to classify my roads in different classes of slope (e.g.: 0-3%, 3-8%, &gt;8%), based on the Z value of the 3D roads.</SPAN><BR /><BR /><SPAN>One way to do that is using the �??Add Z information�?� tool, but the point is that I need to classify it with more details, I mean, regardless the segment division of my feature class.</SPAN><BR /><SPAN>For example, if I have a 5 km segment, instead of calculate the average slope value for the segment, I want to classify it in different classes of slope, and split this segment for each class.</SPAN><BR /><BR /><SPAN>Any idea?</SPAN><BR /><BR /><SPAN>Tks!</SPAN></BODY></HTML> Thu, 14 Mar 2013 16:51:31 GMT https://community.esri.com/t5/3d-questions/3d-polyline-how-to-classify-by-slope/m-p/248286#M1489 ArthurVrechi 2013-03-14T16:51:31Z Re: 3D Polyline - How to classify by slope? https://community.esri.com/t5/3d-questions/3d-polyline-how-to-classify-by-slope/m-p/248287#M1490 <HTML><HEAD></HEAD><BODY><SPAN>1) Create a slope raster from your DTM</SPAN><BR /><SPAN>2) Reclass that slope raster into your discrete classes (i.e. 0-3, 3-8 etc)</SPAN><BR /><SPAN>3) Convert that classified raster into polygons</SPAN><BR /><SPAN>4) Intersect (or identity) your road line and slope polygons.</SPAN><BR /><BR /><SPAN>This should give you the line split at each class boundary and with the class values written to the attribute table (I haven't actually gone through this process to test but it should be something like that <span class="lia-unicode-emoji" title=":slightly_smiling_face:">🙂</span></SPAN><BR /><BR /><SPAN>Cheers</SPAN></BODY></HTML> Sun, 17 Mar 2013 19:14:53 GMT https://community.esri.com/t5/3d-questions/3d-polyline-how-to-classify-by-slope/m-p/248287#M1490 TimBarnes 2013-03-17T19:14:53Z Re: 3D Polyline - How to classify by slope? https://community.esri.com/t5/3d-questions/3d-polyline-how-to-classify-by-slope/m-p/248288#M1491 <HTML><HEAD></HEAD><BODY><SPAN>Thanks Tim. But, in this case, I'll just get the terrain slope where the road is located, and not the road slope. For example, sometimes the road is located on a downhill, but not crossing the slope, but following the line of same altittude.</SPAN><BR /><BR /><SPAN>I could solve my problem spliting my polilyne at vertices (or at determined meters), calculating the slopes by using "add Z information" tool and grouping it.</SPAN><BR /><BR /><SPAN>Cheers!</SPAN></BODY></HTML> Mon, 18 Mar 2013 00:02:11 GMT https://community.esri.com/t5/3d-questions/3d-polyline-how-to-classify-by-slope/m-p/248288#M1491 ArthurVrechi 2013-03-18T00:02:11Z Re: 3D Polyline - How to classify by slope? https://community.esri.com/t5/3d-questions/3d-polyline-how-to-classify-by-slope/m-p/248289#M1492 <HTML><HEAD></HEAD><BODY><SPAN>Hola a todos, no se si alguien me podria dar una ayuda, tengo un archivo en formato .mxd, y la verdad quiero graficarl en 3D Polyline, y me duele la cabeza buscando de que manera, es una area de un parque nacional, que me gustaria proyectalo en Espacio 3D para asi oder apreciar mucho mas todas sus caracteristicas que posee dicha area, tanto altura, profundidades, caminos, rios, pendientes y demas detalles que me son utiles pa asi monitorear mejor.</SPAN><BR /><BR /><SPAN>Por favor denme una ayuda pa lograrlo.</SPAN><BR /><BR /><SPAN>Muchas gracias, se lo agradecere de corazon.</SPAN></BODY></HTML> Mon, 09 Sep 2013 03:53:26 GMT https://community.esri.com/t5/3d-questions/3d-polyline-how-to-classify-by-slope/m-p/248289#M1492 Daniel_AlexanderRosalez_Sanche 2013-09-09T03:53:26Z Re: 3D Polyline - How to classify by slope? https://community.esri.com/t5/3d-questions/3d-polyline-how-to-classify-by-slope/m-p/248290#M1493 <HTML><HEAD></HEAD><BODY><BLOCKQUOTE class="jive-quote">Hola a todos, no se si alguien me podria dar una ayuda, tengo un archivo en formato .mxd, y la verdad quiero graficarl en 3D Polyline, y me duele la cabeza buscando de que manera, es una area de un parque nacional, que me gustaria proyectalo en Espacio 3D para asi oder apreciar mucho mas todas sus caracteristicas que posee dicha area, tanto altura, profundidades, caminos, rios, pendientes y demas detalles que me son utiles pa asi monitorear mejor.<BR /><BR />Por favor denme una ayuda pa lograrlo.<BR /><BR />Muchas gracias, se lo agradecere de corazon.</BLOCKQUOTE><BR /><BR /><BR /><SPAN style="font-style:italic;">FYI; included link to Spanish Forum and some introductory topics in Spanish in answer below.</SPAN><BR /><BR /><BR /><SPAN>Hola DanielAlexandar,</SPAN><BR /><BR /><SPAN>Te recomendaría que colocas tu pregunta en el foro en Español.

Normalmente contiene referencias a capas de datos (layers) y su forma de visualización. Lo que entiendo de tu pregunta, es que quieres visualizarla en 3D. Para este fin ArcGIS tiene las aplicaciones ArcScene y ArcGlobe (que requieren la extensión 3D Analyst). </SPAN><BR /><BR /><SPAN>Para conseguir más información te recomiendo comenzar por un recorrido rápido por ArcMap:</SPAN><BR /><A href="http://help.arcgis.com/es/arcgisdesktop/10.0/help/index.html#/na/006600000332000000/">http://help.arcgis.com/es/arcgisdesktop/10.0/help/index.html#/na/006600000332000000/ </A><BR /><BR /><SPAN>.. y luego leer el tutorial de ArcGIS 3D Analyst:</SPAN><BR /><A href="http://help.arcgis.com/es/arcgisdesktop/10.0/help/index.html#//00q800000093000000">http://help.arcgis.com/es/arcgisdesktop/10.0/help/index.html#//00q800000093000000 </A><BR /><BR /><SPAN>Cordialmente,</SPAN><BR /><BR /><SPAN>Xander</SPAN></BODY></HTML> Mon, 09 Sep 2013 07:52:21 GMT https://community.esri.com/t5/3d-questions/3d-polyline-how-to-classify-by-slope/m-p/248290#M1493 XanderBakker 2013-09-09T07:52:21Z
