`salvus.flow.simple_config.source.transformations`

Utils for source coordinate transformations.

Functions

`geocentric_to_utm()`

def geocentric_to_utm(
    latitude: float, longitude: float, utm_crs: pyproj.crs.crs.CRS
) -> tuple[float, float]: ...

Convert geocentric latitude and longitude coordinates to UTM coordinates.

Parameters

latitude float — The geocentric latitude in degrees.
longitude float — The geocentric longitude in degrees.
utm_crs pyproj.crs.crs.CRS — The UTM coordinate system to convert to.

Returns tuple[float, float]

`spherical_source_to_utm()`

def spherical_source_to_utm(
    source: seismology.SideSetMomentTensorPoint3D,
    utm_crs: pyproj.crs.crs.CRS,
    side_set_name: str = "z1",
) -> cartesian.SideSetMomentTensorPoint3D: ...

Convert a spherical Salvus moment tensor source to a source in a UTM domain (ENU coordinate system).

Parameters

source seismology.SideSetMomentTensorPoint3D — The spherical moment tensor source.
utm_crs pyproj.crs.crs.CRS — The UTM coordinate system to convert to.
side_set_name str — The name of the side set that the source is attached to.

Returns cartesian.SideSetMomentTensorPoint3D — The converted source.

`utm_source_to_spherical()`

def utm_source_to_spherical(
    source: seismology.SideSetMomentTensorPoint3D, utm_crs: pyproj.crs.crs.CRS
) -> cartesian.SideSetMomentTensorPoint3D: ...

Convert a UTM Salvus moment tensor source to a source in a spherical domain (ENU coordinate system).

Parameters

source seismology.SideSetMomentTensorPoint3D — The UTM moment tensor source.
utm_crs pyproj.crs.crs.CRS — The spherical coordinate system to convert to.

Returns cartesian.SideSetMomentTensorPoint3D — The converted source.

`utm_to_geocentric()`

def utm_to_geocentric(
    easting: float, northing: float, utm_crs: pyproj.crs.crs.CRS
) -> tuple[float, float]: ...

Convert UTM coordinates to geocentric latitude and longitude coordinates.

Parameters

easting float — The easting in meters.
northing float — The northing in meters.
utm_crs pyproj.crs.crs.CRS — The UTM coordinate system to convert from.

Returns tuple[float, float]
