Name

rtree-build — create a serialised R-tree from CSV rectangle data

Synopsis

rtree-build [-d dimension] [-h ] [-l ] [-o file] [-q ] [-v ] [-V ] [file]

DESCRIPTION

The rtree-build program reads CSV files specifying a collection of rectangles, cuboids or higher-dimensional hyperectangles and writes a serialised R-tree to output. Such R-trees can be loaded quickly into programs using librtree.

OPTIONS

-d, --dimension dimension

Specify the dimension of the R-tree to build.

-h, --help

List the program options.

-l, --split-linear

Use the linear splitting strategy, which builds the R-tree more quickly, but results in a lower-quality tree with slower queries.

See also the --split-quadratic option.

-o, --output file

Write the output to file, rather than stdout.

-q, --split-quadratic

Use the quadratic splitting strategy, which builds the R-tree more slowly, but results in a higher quality tree with faster queries.

See also the --split-linear option.

-v, --verbose

Verbose operation.

-V, --version

Version information.
