pyart.map#

Description

Mapping (pyart.map)#

Py-ART has a robust function for mapping radar data from the collected radar coordinates to Cartesian coordinates.

Mapping to grid#

grid_from_radars(radars, grid_shape, grid_limits)

Map one or more radars to a Cartesian grid returning a Grid object.

map_to_grid(radars, grid_shape, grid_limits)

Map one or more radars to a Cartesian grid.

map_gates_to_grid(radars, grid_shape, ...[, ...])

Map gates from one or more radars to a Cartesian grid.

Examples of ROI (region of interest)#

example_roi_func_constant(zg, yg, xg)

Example RoI function which returns a constant radius.

example_roi_func_dist(zg, yg, xg)

Example RoI function which returns a radius which grows with distance.

example_roi_func_dist_beam(zg, yg, xg)

Example RoI function which returns a radius which grows with distance and whose parameters are based on virtual beam size.

Classes

GateMapper(src_radar, dest_radar[, ...])

The GateMapper class will, given one radar's gate, find the gate in another radar's volume that is closest in location to the specified gate.

Functions

example_roi_func_constant(zg, yg, xg)

Example RoI function which returns a constant radius.

example_roi_func_dist(zg, yg, xg)

Example RoI function which returns a radius which grows with distance.

example_roi_func_dist_beam(zg, yg, xg)

Example RoI function which returns a radius which grows with distance and whose parameters are based on virtual beam size.

get_earth_radius(latitude)

Computes the earth radius for a given latitude

grid_from_radars(radars, grid_shape, grid_limits)

Map one or more radars to a Cartesian grid returning a Grid object.

map_gates_to_grid(radars, grid_shape, ...[, ...])

Map gates from one or more radars to a Cartesian grid.

map_to_grid(radars, grid_shape, grid_limits)

Map one or more radars to a Cartesian grid.

polar_to_cartesian(radar_sweep, field_name)

Interpolates a PPI or RHI scan in polar coordinates to a regular cartesian grid of South-North and West-East coordinates (for PPI) or distance at ground and altitude coordinates (for RHI)
