Adding Layers to a Scene

Usage Instructions

The Data group on the Scene tab and the right-click menu of layers in the layer manager organize the functionality for adding various types of data to a scene.

Any dataset can be added to a scene window as long as its extent is within the range "Top=90, Bottom=-90, Left=-180, Right=180". Currently, data types that can be added to a scene include 2D/3D point/line/region datasets, text datasets, network datasets, image datasets, raster datasets, LAS datasets, image tile data, terrain tile data, 3D models, KML data, images, 3D model tiles, and online services.

To add dataset-type data to a scene, you can select the desired dataset(s) in the workspace manager and drag them directly into the currently opened scene window; or right-click the dataset(s) and choose Add to New Scene or Add to Current Scene. Batch adding datasets is supported. To add other types of data to a scene, you need to use the corresponding buttons and panels.

The following describes the functions of each control in the Data group on the Scene tab:

  • Tile: Adds existing tile data to the currently opened scene window, including: image tile files (*.sci3d; *.sci; *.sit; *.tiff), 3D terrain tile files (*.sct), 3D vector tile files (*.scv), spatial 3D model tile files (*.scp), global map tile files (*.sci), raster volume data tile files (*.scvo).
  • KML: Creates/Adds KML/KMZ data in the currently opened scene window.
  • Screen Overlay: Adds an image as a screen overlay to the currently opened scene window.
  • Thematic Map: Creates thematic maps based on vector data in the currently opened scene window.
  • Online Map: Opens a specified online map in the currently opened scene window.

The following describes the data-related functions in the right-click menu for General Layers and Terrain Layers in the layer manager:

  • Load 3D Tiles: Adds existing tile data to the currently opened scene window, including: image tile files (*.sci3d; *.sci; *.sit; *.tiff), 3D vector tile files (*.scv), spatial 3D model tile files (*.scp), global map tile files (*.sci), raster volume data tile files (*.scvo).
  • Load/Create KML: Creates/Adds KML/KMZ data in the currently opened scene window.
  • Load CityGML: Loads CityGML data for browsing and viewing in the currently opened scene window.
  • Open iServer Service Layer: Adds data from a published iServer service scene to the current scene as a layer.
  • Open OGC Service Layer: Adds data from a published OGC service to the current scene as a layer.
  • Open Tianditu Map Service Layer: Loads layers from the WMTS service of the Tianditu Map Service into the currently opened scene window.
  • Open ArcGIS Map Service: Loads non-encrypted ArcGIS map services into the currently opened scene window.
  • Open Terrain Tiles: Adds existing 3D terrain tile data (*.sct) to the currently opened scene window. Currently, opening either a single TIN terrain tile or multiple DEM terrain tiles in a scene is supported.
  • Open iServer Service Scene Terrain Layer: Adds terrain data from a published iServer service scene to the current scene as a terrain layer.
Tip:
  • When adding a raster dataset to a scene, a prompt dialog appears asking you to confirm whether to load the raster dataset as terrain data or image data into the scene. When adding multiple raster datasets, you can select "Apply this operation to all subsequent datasets" to load them into the scene in a unified manner.
  • When a text dataset is added to a scene, the text style of the dataset is used by default, meaning the text dataset will appear in the 3D scene with the same style it has in a 2D map.
  • When excessively large image data is loaded into a scene, a prompt dialog suggests creating an image pyramid before loading. If multiple image datasets are being loaded and the user selects "Apply this operation to all subsequent datasets", all large-memory image datasets added at that time will have image pyramids created and then be loaded into the scene.
  • Due to different data loading strategies, when adding the same model dataset to the same scene window where one is in a geographic coordinate system and the other is in a projected coordinate system, the two model data positions in the scene may be offset.
  • Loading multiple DEM terrain tiles or raster datasets as terrain layers in a scene is supported. When loading multiple DEM terrain tile datasets that have overlapping spatial extents, it is recommended to keep the starting level numbers consistent for the tile data with overlapping extents.
