BPMF.ploting_utils

BPMF.plotting_utils.add_scale_bar(ax, x_start, y_start, distance, source_crs, orientation='longitudinal', **kwargs)

Parameters:

• ax (GeoAxes instance) – The axis on which we want to add a scale bar.

• x_start (float) – The x coordinate of the left end of the scale bar, given in the axis coordinate system, i.e. from 0 to 1.

• y_start (float) – The y coordinate of the left end of the scale bar, given in the axis coordinate system, i.e. from 0 to 1.

• distance (float) – The distance covered by the scale bar, in km.

• source_crs (cartopy.crs) – The coordinate system in which the data are written.

• orientation (string, default to 'longitudinal') – Either ‘longitudinal’ or ‘latitudinal’. Determine the orientation of the scale bar.

BPMF.plotting_utils.uncertainty_ellipse(hmax_uncertainty_km, hmin_uncertainty_km, hmax_azimuth_deg, longitude_center, latitude_center, num_points=100)

Compute a set of longitude and latitude points that describe the uncertainty ellipse in the horizontal plane.

Parameters:

• hmax_uncertainty_km (float) – The length of the major axis of the uncertainty ellipse in kilometers.

• hmin_uncertainty_km (float) – The length of the minor axis of the uncertainty ellipse in kilometers.

• hmax_azimuth_deg (float) – The azimuth angle of the major axis of the uncertainty ellipse in degrees.

• longitude_center (float) – The longitude coordinate of the center point of the ellipse.

• latitude_center (float) – The latitude coordinate of the center point of the ellipse.

• num_points (int, optional) – The number of points used to describe the ellipse, default is 100.

Returns:

• longitude_ellipse (numpy.ndarray) – The longitude coordinates of the points that make up the uncertainty ellipse.

• latitude_ellipse (numpy.ndarray) – The latitude coordinates of the points that make up the uncertainty ellipse.

BPMF.plotting_utils.vertical_uncertainty_ellipse(cov_mat, longitude_center, latitude_center, depth_center, horizontal_direction='longitude', num_points=100)

Compute a set of longitude and latitude points that describe the uncertainty ellipse in the vertical plane.

Parameters:

• cov_mat (numpy.ndarray) – The (3x3) covariance matrix returned by Event.relocate(method=’NLLoc’).

• longitude_center (float) – The longitude coordinate of the center point of the ellipse.

• latitude_center (float) – The latitude coordinate of the center point of the ellipse.

• depth_center (float) – The depth, in km, of the center point of the ellipse.

• horizontal_direction (str, optional) – Either ‘longitude’ or ‘latitude’. Define the x-coordinate of the plane.

• num_points (int, optional) – The number of points used to describe the ellipse, default is 100.

Returns:

• longitude_ellipse (numpy.ndarray) – The longitude coordinates of the points that make up the uncertainty ellipse.

• latitude_ellipse (numpy.ndarray) – The latitude coordinates of the points that make up the uncertainty ellipse.

• depth_ellipse (numpy.ndarray) – The depth, in km, of the points that make up the uncertainty ellipse.
