Constructor Detail

Proj

Proj(srs)

Provides latitude/longitude to map projection (and vice versa) transformation methods. Initialized with EPSG codes. Has properties for units and title strings. All coordinates are handled as points which is a 2 element array where x is the first element and y is the second. For the Forward() method pass in lat/lon and it returns map XY. For the Inverse() method pass in map XY and it returns lat/long. TBD: retrieve initialization params (and conversion code?) from a web service

Parameters:

srs
