The 3D mesh layer (3DML) format is a data format for fully textured and geospatially-enabled urban models. Developed by Skyline Software Systems Inc., 3DMLs are created in Skyline's TerraBuilder CityBuilder application by merging several different types of model layers into a single, stream-optimized layer. When loaded into 3D GIS visualization software, 3DMLs support advanced geospatial analysis. Overview 3DMLs are created in Skyline's TerraBuilder CityBuilder by merging 3D mesh models together with classification layers, individually modeled layers, and BIM datasets into a stream-optimized, geospatially enabled mesh layer (3DML). A simple 3DML from a single point shapefile with individually referenced 3D model files can be created in Skyline's TerraExplorer Pro. Included Files 3DMLs can include any of the following layer types: 	Model Layers – Point feature layers that reference individual models. A layer attribute field is used to define which model is associated with each of the layer’s points. 	BIM Layers – Building Information Modeling layers that provide support for the entire building life cycle from planning and design through construction and facility operation 	Mesh Layers – 3D mesh models, which are either generated by Skyline's TerraBuilder PhotoMesh or created in an external application as OSGB layers. •	Classification Layers – Polygon feature layers such as building footprints that classify areas of the mesh model in order to fully enable spatial and attribute queries. Distributing and Loading 3DMLs 3DMLs can be streamed from 3DML files and from the Oracle Spatial, SQL, and PostgreSQL servers to remote mobile and desktop clients using Skyline’s TerraGate 3D Mesh Layer service. Remote clients can update 3DML’s attribute data, writing all changes directly to the data source. Advantages of the 3DML Format 	3DMLs can store any number of mesh models with BIM and other model data sets, reprojecting all layers to the project’s coordinate system. 	Fully textured model 	Optimizes models for desktop, web, and mobile use References Link to CityBuilder page on website??
