Split processing

Click on Split block to start the split processing.

Split divides the aerial block into several parts according to a regular 2D grid.

To perform a reconstruction of all parts, you must take care on further reconstruction spatial framework settings in order to get compatible tiles and coordinate system.

When defining a reconstruction for one block part, please define the spatial framework as follows:

  • Use the same SRS to define all reconstructions spatial framework.
  • Use regular planar grid as tiling mode
  • Use a tile size that divides the block size.
  • Use (0 ; 0), or multiples of the block size, as custom tiling origin coordinates.
  • Use the region of interest corresponding to the block part.

Adequate reconstruction spatial framework settings are reminded in the split report and recalled in the description of each block part.

Note: Once split, the parent block may be unloaded to save memory and loading/saving time (right click > Unload). See also Load/unload blocks.

The split process also generates a KML file useful to get an overview of computed sub-block regions.

The KML file is accessible in the project folder: myBlock - sub-block regions.kml.
