Build Mosaic Lines

Feature Description

Build Mosaic Lines can automatically generate mosaic lines for all data in a mosaic dataset according to the specified pyramid levels. After generating the mosaic lines, when performing image mosaicking, overlapping areas will be selected or discarded based on the mosaic lines.

Parameter Description

Parameter Name Parameter Interpretation Parameter Type
Dataset

Select the mosaic dataset for which to build mosaic lines. The default is the image color balancing mosaic dataset. Supports selecting a true color mosaic dataset.

 DatasetMosaic
Method to Create Seamlines

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

  • GraphCut: Builds the most detailed mosaic lines but takes the longest time.
  • Voronoi: The constructed mosaic lines may cross roads, buildings, etc., with lower accuracy but shorter time.
  • Border: Uses image outlines as mosaic lines, low accuracy, shortest time.
 BuildSeamLinesMethod
Refinement Level This parameter is effective only when the method to create seamlines is GraphCut. Provides three options: High, Medium, Low. The higher the refinement level, the better the generated mosaic lines. SeamlineRefinementLevel
Image Sorting Method

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

  • Priority time: Sort by image acquisition time from newest to oldest, prioritizing the latest data.
  • Priority resolution: Sort by spatial resolution from highest to lowest, prioritizing high-definition images.
 ImageSortMethod
Mask Data Not checked by default. If checked and a mask dataset is set, the system will exclude that area when constructing mosaic lines. Boolean
Datasource Available after checking Mask Data. Specifies the datasource 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
Remove Cloud Zone Available after checking Mask Data. Sets whether to remove cloud zones from the image. Not checked by default. When checked, cloud zones will be removed during the building of mosaic lines, generating cloud-free DOM mosaic results. This operation may cause missing images within the cloud zone, so use with caution. Boolean

Output Result

  • Update the mosaic line information within the imported tesselation dataset for subsequent mosaicking operations.
  • In the result path/DOM/Seamline folder, build vector region files (SeamLinesResult.shp and SeamLinesResult.udbx) as viewable, inspectable, and archivable entity results.
