gdal vector sort sorts the features in a vector dataset according to the position of its geometries. The sorting method can be specified via --method, with Hilbert and Sort-Tile-Recursive (STRTree) algorithms available.

Features that have null or empty geometries will be placed at the end of the sorted dataset.

This command can also be used as a step of gdal vector pipeline.

NOTE:

Use of the STRtree algorithm requires a GDAL build against the GEOS library.

The name of the geometry field by which features should be sorted.
Specifies the sorting method. Available options are:
  • hilbert : default method. Geometries are sorted according to the Hilbert code of the center point of their bounding box
  • strtree : Geometries are sorted by constructing a sort-tile-recursive tree using the GEOS library and performing a depth-first iteration.
Write the input features to a temporary file from which they can be read in sorted order. Avoids the need to load the entire input layer into memory.

The program returns status code 0 in case of success, and non-zero in case of error (non-blocking errors emitted as warnings are considered as a successful execution).
