3.14.2 wradlib.verify.PolarNeighbours
class wradlib.verify.PolarNeighbours(r, az, sitecoords, projstr, x, y, nnear=9)
For a set of projected point coordinates, extract the neighbouring bin values from a data set in polar coordinates.
Use as follows:
First, create an instance of PolarNeighbours by passing all the information needed to georeference the polar
radar data to the points of interest (see parameters)
Second, use the method extract in order to extract the values from a data array which corresponds to the polar
coordinates
Parameters r : array of floats
(see georef for documentation)
az : array of floats
(see georef for documentation)
sitecoords : sequence of floats
(see georef for documentation)
projstr : string
(see georef for documentation)
x : array of floats
x coordinates of the points in map projection corresponding to projstr
y : array of floats
y coordinates of the points in map projection corresponding to projstr
nnear : int
number of neighbouring radar bins you would like to find
Methods
extract(vals)
get_bincoords()
get_bincoords_at_points()
Extracts the values from an array of shape (azimuth angles, range gages)
Returns all bin coordinates in map projection
Returns bin coordinates only in the neighbourshood of points
