Now, you will modify the display of the 2D buildings layer so you can see them more clearly. Later on, it will contain the 3D buildings you construct.
Rasters to multipatch Patch#
The geometric information stored in a patch may be triangles, triangle fans, triangle strips, or. Patches store texture, color, transparency, and geometric information representing parts of a feature. are used to define the triangle strips in the multipatch GeoVolume features. There is also another layer, Penn_State_3D_Buildings, which is a multipatch layer and can store complex textured 3D shapes. A multipatch feature is a GIS object that stores a collection of patches to represent the boundary of a 3D object as a single row in a database. In ArcGIS Pro, mosaic datasets serve a similar purpose to raster catalogs. You will set the elevation properties for this layer so that you can better see the buildings.
Then use the Mosaic tool to mosaic the buildings raster with the DEM raster.
Rasters to multipatch plus#
des donnes vectorielles et raster ainsi que des donnes plus complexes. Generate 3D multipatch vector features out of lidar points classified as buildings, a DEM raster, and building footprints. To accomplish this, first use this tool to convert the multipatch features into a raster. 9.1 (hors formats orients 3D et spcifiques la gestion du multipatch). That's because they are shown in a 3D environment and the 2D polygons are partially covered by small differences in the terrain elevation. Generate a building raster, a building feature class, and clean up the building polygons. So finally I could convert multipatch file to raster using 'Multipatch to Raster' tool in ArcGIS Pro. The same 2D building footprint layer, Penn_State_2D_Footprints, is displayed in the Scene view, but you'll notice that the two building footprints aren't fully displayed and seem to sink into the ground. Local scenes are useful to display 3D datasets that have a limited spatial extent, and are displayed with a projected coordinate system, such as a city or, in the case of this exercise, a university campus.
