Mosaic

Function Description

The oblique photography data mosaic function performs a mosaic operation between the selected oblique photography layer and a specified mosaic surface.

Function Entry

  • 3D Geographic Design Tab -> Oblique Photography Data Operations Group -> Mosaic Button

Operation Steps

  1. In a new or existing scene, load oblique photography 3D model S3M tile data. Then, use the layer's right-click menu "Quick Locate to This Layer" to move the camera. Adjust the camera to a convenient viewing angle for the mosaic operation by holding down the mouse wheel in the scene window.
  2. In the 3D Geographic Design tab, within the Oblique Photography Data Operations group, click the Mosaic button. The "Oblique Photography Data Mosaic" panel will pop up for parameter settings.
    • Layer Selection: Click the dropdown arrow of the "Oblique Photography Layer" combo box to select the layer to be mosaicked.
    • Mosaic Surface Determination: Select either "Select Surface" or "Draw Surface" to determine the type of mosaic surface. When selecting "Draw Surface," the toolbar provides three methods to define the mosaic surface: "Rectangle," "Polygon," and "Import."
      • Select Surface: Select a surface object in the scene as the mosaic surface. To select multiple surfaces for the operation, hold down the Shift key and then select them in the scene.
      • Rectangle or Polygon: Move the mouse to the scene, click the left mouse button to start drawing a rectangle or polygon as the mosaic surface, and click the right mouse button to end the drawing.
      • Import Mosaic Surface: Click the import button to pop up the import dialog box, which supports importing a surface dataset from an existing data source in the Workspace Manager as the mosaic surface.
    • Export Mosaic Surface: Supports exporting the drawn mosaic surface by clicking the "Export" button.
    • Parameter Settings:
      • Additional Height (meters): Sets the additional bottom height of the mosaic surface. This operation does not change the original bottom height value of the mosaic surface. The default is 0, in meters.
      • Slope Width (meters): Directly input a numerical value to determine the width of the slope protection, in meters.
      • Effective Height Range: When checked, supports setting the effective height range for the mosaic.
        • Bottom Elevation: Sets the bottom elevation value relative to the mosaic surface, in meters. This value determines the data range below the mosaic surface to be included in the mosaic calculation.
        • Top Elevation: Sets the top elevation value relative to the mosaic surface, in meters. This value determines the data range above the mosaic surface to be included in the mosaic calculation.
      • "Preview" Checkbox: Unchecked by default. When the "Preview" checkbox is checked, the mosaic result can be previewed in real time.
  3. After the settings are complete, click "OK" to perform the mosaic operation. An example result of the mosaic is as follows:
  4. Click "Undo" to revert the result of the oblique photography model mosaic operation.
