| Summary : Convert coordinates between geodetic WGS84 and Swedish grid RT90 and SWE[cut]
|
Description :
Convert coordinates between geodetic WGS84 and Swedish grid RT90 and
SWEREF99 systems.
Implementation of \"Gauss Conformal Projection (Transverse Mercator),
Kr�gers Formulas\".
Parameters for SWEREF99 lat-long to/from RT90 and SWEREF99 coordinates
(RT90 and SWEREF99 are used in Swedish maps).
* $grid = Geo::SweGrid->new($projection)
Constructor for Geo::SweGrid
Creates an instance and sets up parameters for the given RT90 or
SWEREF99TM projection. Note: Parameters for RT90 are choosen to eliminate
the differences between Bessel and GRS80-ellipsoides. Bessel-variants
should only be used if lat/long are given as RT90-lat/long based on the
Bessel ellipsoide (from old maps).
Parameters:
$projection (string). Must match a recognized projection.
List of supported projections:
rt90_0.0_gon_v
rt90_2.5_gon_o
rt90_2.5_gon_v
rt90_5.0_gon_o
rt90_5.0_gon_v
rt90_7.5_gon_v
bessel_rt90_0.0_gon_v
bessel_rt90_2.5_gon_o
bessel_rt90_2.5_gon_v
bessel_rt90_5.0_gon_o
bessel_rt90_5.0_gon_v

Example:
my $grid = Geo::SweGrid->new(\"rt90_2.5_gon_v\") or die \"No grid, projection not recognized\";
Returns:
the created instance;
* ($x, $y) = $grid->geodetic_to_grid($lat, $lon)
Conversion from geodetic coordinates to grid coordinates.
Parameters:
$latitude (number)
$longitude (number)
Example:
my ($x, $y) = $grid->geodetic_to_grid(63.1530261140462, 11.8353976399345);
Returns:
the x and y grid coordinates;
* ($lat, $lon) = $grid->grid_to_geodetic($x, $y)
Conversion from grid coordinates to geodetic coordinates.
Parameters:
$x (number)
$y (number)
Example:
my ($lat, $lon) = $grid->grid_to_geodetic(7011002, 1299996);
Returns:
the latitude and longitude geodetic coordinates;
