getPointResolution

Get the resolution of the point in degrees. For projections with degrees as the unit this will simply return the provided resolution. For other projections the point resolution is estimated by transforming the center pixel to EPSG:4326, measuring its width and height on the normal sphere, and taking the average of the width and height.

Methods

getAxisOrientation

Get the axis orientation of this projection. Example values are: enu - the default easting, northing, elevation. neu - northing, easting, up - useful for "lat/long" geographic coordinates, or south orientated transverse mercator. wnu - westing, northing, up - some planetary coordinate systems have "west positive" coordinate systems

• proj.js, line 161

Returns:

Axis orientation.
