The Profile Graph tool in ArcGIS does not work if the input DEM and the selected line feature are not in the same coordinate system. To test this statement, I used a DEM in UTM coordinates and a line feature class in US State Plane. My result was a graph with a constant elevation of one. I reprojected the line feature class to the UTM coordinate system and ...

You could use the &&& operator. It returns true if two n-d bounding boxes intersect: SELECT 'POINT Z (0.5 0.5 0.5)' &&& 'LINESTRING Z(0 0 0, 1 1 1)' AS intersects; intersects ------------ t (1 row) SELECT 'POINT Z (1.5 0.5 0.5)' &&& 'LINESTRING Z(0 0 0, 1 1 1)' AS intersects; intersects ------------ f (1 row) For ...

There might be a folder in webApps where you had placed your terrain files. By saying this 'localhost:8081' you mean to say all my files are placed in WebApps root folder. Create a folder place all terrain files in it, append folder name to after port with slash and give it a shot.

ESRI complete and less hassle. ESRI is introducing 3D across web and devices, check out ESRI Dev Summit for details. Beta is coming after 20th of next month. Pros 3D in browser using webGL Have a look at caniuse.com to see if your client browser supports WebGL if they do you need not to write native apps for mobile. In case your client mobile browsers do ...

Yes, you can use DEM. By default you will use cesiums default STK world terrain provider There is an example how to enable terrain provider for cesium at ol3-cesium website var ol3d = new olcs.OLCesium({map: map}); // map is the ol.Map instance var scene = ol3d.getCesiumScene(); var terrainProvider = new Cesium.CesiumTerrainProvider({ url: ...

I also wrote to SimUrban and received this reply, which suggests that it is not possible to export the building models directly from SimUrban. Simurban is a closed system and most of the native files can’t be exported or migrated to another system. The terrain height data can be exported as points only in ASCII format. The base data sets ...

Did you create an n-d index on your geometry column? CREATE INDEX foo_gix_nd ON foo USING GIST (the_geom gist_geometry_ops_nd); Some more information is available here: http://suite.opengeo.org/opengeo-docs/dataadmin/pgBasics/3d_types.html

This will not be mych of an answer; You may be able to "sort of" visualize an already finished mesh in ArcScene you will definitely NOT be able to create it in ArcGIS. I don't have much experience with 3D AutoCAD but its likely possible with some autodesk / plugin product. I've used a fantastic software called Leapfrog Mining in the past to model complex ...

Under the View tab on the Ribbon in Pro you will see on the left hand side the buttons global and local. This will convert your scene from the global scene you started with to a local scene where you can further change the coordinate system of the local scene.

You probably created a 2d index, not an n-d index, which is what the &&& operator uses. CREATE INDEX particles_gix ON particles USING GIST (position gist_geometry_ops_nd);

I know a bit late to reply to this, but PostGIS 2.2 for PostgreSQL 9.5, just recently committed <<->> operator which is a KNN distance for 3D. For 9.5 it returns true 3d distance, for 9.4 and below, just uses 3D bounding box centroid (so would work fine for points). Details here: http://postgis.net/docs/manual-dev/geometry_distance_centroid_nd.html ...
