- class wradlib.verify.PolarNeighbours(r, az, sitecoords, proj, 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.
numpy.ndarray) – array of x coordinates of the points in map projection corresponding to proj
numpy.ndarray) – array of y coordinates of the points in map projection corresponding to proj
int) – number of neighbouring radar bins you would like to find
Extracts the values from an array of shape (azimuth angles, range gages) which correspond to the indices computed during initialisation
Returns all bin coordinates in map projection
Returns bin coordinates only in the neighbourhood of points
