Detailed Description

Simple spherical coordinate computation. Does not handle projections, but earth coords.

Variable names

Note. This is a model for ideal sphere, defined as

"+proj=longlat +R=6371000 +no_defs";

where R is the radius of the Earth. Use getDatumString() to get the actual std::string.

Note that this is not equivalent with

EPSG:4326 = "+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs";

void info ( std::ostream & ostr = std::cout )

Determines the bounding box (in degrees) of the circular radar measurement area.

Info

Sets surface coordinates (phiBin, thetaBin) according to polar coordinates.

Polar coordinates.

Parameters

alpha	is azimuth in radians,
range	in metres.

Explanation? Sets surface coordinates (phiBin, thetaBin) according to polar coordinates.

lon = atan2((e11*x1 + e21*x2 + p01*x3), (e12*x1 + e22*x2 + p02*x3));

Radar site latitude and longitude in radians.

Set origin in radians.

To speed up the computation of bin locations, some internal variables are set at this stage.

Parameters

theta	latitude in radians
phi	longitude in radians
