NAME

Geo::JSON::Utils - Util methods for Geo::JSON classes

SYNOPSIS

use Geo::JSON::Utils qw/ compare_positions compute_bbox /;

DESCRIPTION

Util methods for Geo::JSON

METHODS

compare_positions

if (Geo::JSON::Utils::compare_positions( $pt1, $pt2 )) {
    # positions of points are the same
}

Compare two points. Compares in up to three dimensions. Any further dimensions are ignored.

compute_bbox

my $bbox = Geo::JSON::Utils::compute_bbox( \@positions );

Computes a bounding box for an arrayref of positions. The bounding box is a list of all minimum values for all axes followed by all maximum values. The values are in the order the axis they appear in the position geometry.

Assumes all points will have same number of dimensions as the first.

TODO

  • Improve comparisons of floating point coordinates, look at stringification issues, etc.
