model.location

class Location(**kwargs)[source]

Geographical location.

The location is given by a reference point at the earth’s surface (lat, lon) and a cartesian offset from this point (north_shift, east_shift, depth). The offset corrected lat/lon coordinates of the location can be accessed though the effective_latlon, effective_lat, and effective_lon properties.

lat

float, optional, default: 0.0

latitude of reference point [deg]

lon

float, optional, default: 0.0

longitude of reference point [deg]

north_shift

float, optional, default: 0.0

northward cartesian offset from reference point [m]

east_shift

float, optional, default: 0.0

eastward cartesian offset from reference point [m]

elevation

float, default: 0.0

elevation [m]

depth

float, default: 0.0

depth [m]

effective_latlon

Property holding the offset-corrected lat/lon pair of the location.

effective_lat

Property holding the offset-corrected latitude of the location.

effective_lon

Property holding the offset-corrected longitude of the location.

same_origin(other)[source]

Check whether other location object has the same reference location.

distance_to(other)[source]

Compute surface distance [m] to other location object.

distance_3d_to(other)[source]

Compute 3D distance [m] to other location object.

All coordinates are transformed to cartesian coordinates if necessary then distance is:

\Delta = \sqrt{\Delta {\bf x}^2 + \Delta {\bf y}^2 +                       \Delta {\bf z}^2}

azibazi_to(other)[source]

Compute azimuth and backazimuth to and from other location object.
