Generate 3D Image Tile

Instructions for use

Image Tile is a 3D tile file generated for image, raster and Mosaic Dataset, which can optimize data display and browsing effect. Raster Dataset and Mosaic DatasetBuild 3D Tile also have the option to generate an Image Tile.

Function entrance

  • Works pace Manager -> Image/Raster DatasetContext Menu -> Generate 3D Tiles.. Options

Operation steps

  1. Select the Generate 3D Tiles.. "In the Image Dataset, Raster Dataset, or Mosaic DatasetContext Menu.
  2. Pop-up "Build 3D Tile" dialog box for Add Data and Set Parameters.
  3. Click to pop up the Select dialog box. The All Data source in the current Workspace is listed on the left side of the dialog box, and all the Datasets in the Datasource are listed on the right side. Users can use the toolbar above the dialog box to filter and search the required Dataset. After the selection is completed, click the "OK" button.
  4. You return to the Build 3D Tile dialog and see the selected Image Dataset and displayed in the list.
  5. Toolbar:
      Select
    • All: Select All in the data list to perform batch operations on the Dataset, such as deletion and Batch Settings Tile parameters.
    • Invert: Select the unselected Dataset in the data list.
    • Delete: Removes the Dataset from the Current Data list.
    • Set Password: is the generated 3D TilesSet Password. The 3D Tiles data after Set Password requires a password to be entered when it is opened. Click the Set Password "button, enter the same password in the Password and Confirm Password boxes, and then click Confirm to complete the Password Settings. It is important to note that only the Compact Storage Format supports Set Password.
      Caution:
        During
      • Batch Settings Tile parameters, you need to click Enter after typing the specific parameter value to make it effective. Otherwise, it may not work to assign the same parameter value in batches.
  6. Data list area:
    • Dataset: shows the name of the data used to generate the video Tile.
    • Datasource: shows the name of the Datasource where the data used to generate the video Tile is located. If the data is added in the form of a file, there is no Datasource, and the display is empty.
    • Tile Type: shows the type of 3D tiles to be generated, in this case "Image". Tile Type: is a Drop-down Button. All Tile Types: supported by the selected data are listed in the drop-down list, and the user can select from them.
    • Scene Type: There are two types of scene types: plane and sphere. When the Dataset is a Planar Coordinate System, the Scene Type can only be set to a plane; when the Dataset is a Geographic Coordinate System, the Scene Type can only be set to a sphere; When the Dataset is a Projected Coordinate System, the Scene Type can be set to a plane or a sphere.
  7. Basic Settings:
    • Tile Name: In the text box to the right of the Tile Name ", enter tile name, which is the name of the root of the tile.
    • Tile Path: Enter the Export Directory of the tile in the text box on the right side of the Tile Path ", which can be a local path or a network path; users can also select the path through the Browse button behind the text box.
  8. Parameter Settings：
    • Organization Type: The system provides 2 organization types, Tile Storage and Block Storage. A block store represents a Data Save in fixed-length blocks. The lower version does not support compatibility when the image is Generate Tiles with block storage type.
    • Storage Type: The system provides 2 Storage Formats, Compact and Raw. The compact representation uses a certain compression and encryption mechanism to compress and encrypt the data when building the Tile; the original representation does not compress the data and retains the original information of the Image Data.
    • Tile format: Set the type of image tile to save. Application supports five image formats including DXTZ, PNG, JPG, PNG-JPG and WEBP.
    • The size of tiles (px): Get the sample size of each tile block file generated after Tile preprocessing, in pixels, i.e. pixes * pixes. Application provides 1024 * 1024, 512 * 512, 256 * 256 and other sizes for users to choose. The user can select the appropriate size.
    • Number of Threads: When Scene Type is spherical, it supports setting the number of threads and sets the number of threads allocated to generate the image Tile. The default value is 1.
    • Start layer, end layer: automatically obtain the layer number of the image Tile, which can be modified.
    • Transparent Color: Used to set a Color Setting in the data as a transparent color, that is, set the Area Setting of the specified color in the data as a transparent effect. Check this box to specify a color to set the Transparent Display.
  9. Tile Bounds
    • Check the "Default range" check box, the range of Dataset is used by default, and the four text boxes on the upper left and lower right display the system Default
      • range; Users can Custom Bounds
    • without checking the "Default" checkbox. There are two ways, one is to select the range of the selected Dataset by selecting Bounds Dataset, and the other is to directly enter the range value in the upper left and lower right text boxes.
  10. "Show Progress Bar" is checked by default, and click the "Generate" button to execute the image Tile processing operation. Each image Tile is stored in a separate folder. For example, the Tile result generated in the example is stored in the "D: \ DatasetDSM @ DatasetDSM" folder, which contains the corresponding image Tile file. The *.sci3d file is the TileConfig File, which marks the range, number of layers, and other information of the Tile.

Remark

  1. For the introduction of Global rules, please refer to the introduction in the Map Tiles Directory Structure .
  2. Only when the data is Geographic Coordinate System, setting the thread parameter to multi-thread is supported.
  3. The combination factor parameter can be set only when the storage type is block storage. The storage data block size in the combination factor is different from the block size (pixel).
  4. The Password Settings feature only works when the Organization Type is Tile Storage and the Storage Format "is Compact.
