Class Etm

New Etm Exact Transverse Mercator coordinate, raising ETMErrors.

Arguments:

• zone - Longitudinal UTM zone (int, 1..60) or zone with/-out latitudinal Band letter (str, '1C'|..|'60X').
• hemisphere - Northern or southern hemisphere (str, 'N[orth]' or 'S[outh]').
• easting - Easting, see falsed (meter).
• northing - Northing, see falsed (meter).
• band - Optional, latitudinal band (str, 'C'|..|'X', no 'I'|'O').
• datum - Optional, this coordinate's datum (Datum, Ellipsoid, Ellipsoid2 or a_f2Tuple).
• falsed - If True, both easting and northing are falsed (bool).
• gamma - Optional meridian convergence, bearing off grid North, clockwise from true North (degrees) or None.
• scale - Optional grid scale factor (scalar) or None.
• name - Optional name (str).
• convergence - DEPRECATED, use keyword argument gamma=None.

Raises:

• TypeError - Invalid or near-spherical datum.
• UTMError - Invalid zone, hemishere, easting, northing, band, convergence or scale.

Overrides: object.__init__

Parse a string to a similar Etm instance.

Arguments:

• strETM - The ETM coordinate (str), see function parseETM5.
• name - Optional instance name (str), overriding this name.

Returns:

The instance (Etm).

Raises:

• ETMError - Invalid strETM.

Overrides: utm.Utm.parse

DEPRECATED, use method Etm.parse.

Decorators:

• @deprecated_method

Convert this ETM coordinate to an (ellipsoidal) geodetic point.

Arguments:

• LatLon - Optional, ellipsoidal class to return the geodetic point (LatLon) or None.
• unfalse - Unfalse easting and northing if falsed (bool).

Returns:

This ETM coordinate as (LatLon) or a LatLonDatum5Tuple(lat, lon, datum, gamma, scale) if LatLon is None.

Raises:

• ETMError - This ETM coordinate's exacTM and this datum incompatible or no convergence transforming to lat- and longitude.
• TypeError - Invalid or non-ellipsoidal LatLon.

Overrides: utm.Utm.toLatLon

Copy this ETM to a UTM coordinate.

Arguments:

• zone - New UTM zone (int).
• eps - Optional convergence limit, EPS or above (float), see method Utm.toLatLon.
• falsed - False both easting and northing (bool).

Returns:

The UTM coordinate (Utm).

Overrides: utm.Utm.toUtm
