Esri Indexed 3D Scene Layer (I3S) Feature Representation
In addition to the generic FME feature attributes that FME Workbench adds to all features (see the chapter About Feature Attributes), this format adds the format-specific attributes described in this section. Geometry TypesThe I3S writer supports two types of scene layers: i3s_3d_object and i3s_terrain_mesh. In FME Workbench, one of these options must be selected when adding the writer feature type to a workspace. i3s_3d_object This layer type contains distinct 3D objects, such as buildings and bridges. These features are placed on the existing terrain or ellipsoid in the scene viewer. i3s_terrain_mesh This layer type contains a single mesh, replacing the existing terrain in the scene viewer. A typical source of data for this layer type would be a DEM raster which has been converted to a mesh. This layer type does not support feature attributes. |
