Build the Tessellation Line

Feature Description

Build the tessellation line can automatically generate seamlines for all data in the mosaic dataset based on specified pyramid levels. After generating the seamlines, during image mosaic, overlapping areas will be selected or discarded according to the seamlines.

SuperMap iDesktopX11i(2023) version starts to support.

Parameter description

Parameter Name parameter interpretation parameter type
Dataset

Select the mosaic dataset that requires building the tessellation line. The default is the image uniform color mosaic dataset, and it supports selecting true color mosaic dataset.

 DatasetMosaic
method to create seamlines

Provides three algorithms: GraphCut, Voronoi, and Border. The default is GraphCut.

  • GraphCut: The constructed seamline is the most precise but takes the longest time.
  • Voronoi: The constructed seamline may pass through roads, buildings, etc., with lower accuracy and shorter time.
  • Border: Uses the image outline as the seamline, with low accuracy and shortest time.
 BuildSeamLinesMethod
refinement level This parameter is only valid when the method to create seamlines is GraphCut. It provides three options: High, Medium, and Low. The higher the refinement level, the better the generated seamline effect. SeamlineRefinementLevel
image sorting method

Sets the sorting method for images in the mosaic dataset when building the tessellation line. Provides two methods: Priority time and Priority resolution. The default is Priority time.

  • Priority time: Sorts images by acquisition time from newest to oldest, prioritizing the latest data.
  • Priority resolution: Sorts images by spatial resolution from high to low, prioritizing high-resolution images.
 ImageSortMethod
mask data By default, it is not checked. If checked and mask data is set, the system will exclude that area before constructing the seamlines. Boolean
Data Source Available after checking Mask Data. Specifies the data source where the mask dataset is located. If executing a production workflow, this parameter is not provided. DataSource
Dataset Available after checking Mask Data. Specifies the mask dataset. If executing a production workflow, the mask data from True Color Output is used by default. DatasetVector

Output Result

  • Updates the seamline information within the imported tessellation dataset for subsequent mosaic operations.
  • Builds vector region files (SeamLinesResult.shp and SeamLinesResult.udbx) in the result path/DOM/Seamline folder, as viewable, checkable, and archivable physical results.
