Convert xy coordinates
This is a python package for converting xy coordinates (in lng,lat order) in numpy array between WGS-84, GCJ-02 and BD-09 system.
The conversion in numpy is much more efficient (50-70 times speedup) compared with previous Python implementations such as eviltransform and coordTransform_py that convert only a single point at each call.
Install the package
pip install xyconvert
from xyconvert import gcj2wgs import numpy as np gcj_xy = np.asarray([[104.07008157, 30.73199687], [104.07008159, 30.73177709], [104.06999188, 30.73147758]]) wgs_xy = gcj2wgs(gcj_xy) print wgs_xy ''' [[104.06756309 30.73437796] [104.06756312 30.73415829] [104.06747357 30.73385904]] '''
