convertbng 0.1.17

Fast lon, lat to BNG conversion

Fast lon, lat to BNG conversion

Uses a Rust 1.x binary to perform fast longitude, latitude to BNG conversion. This module exposes two methods: util.convertbng() – pass a lon, lat. Returns a tuple of Eastings, Northings util.convertbng_list() – pass lists (or Numpy arrays) of lons, lats. Both methods return Easting, Northing tuples (in a list in the case of the latter).

Installation

Installation as a binary wheel using pip, for OS X: pip install convertbng Binary wheels aren’t yet available for Linux or Windows, but installation directly from Github works: pip install git+git://github.com/urschrei/convertbng.git

Usage

from convertbng.util import convertbng, convertbng_list

res = convertbng(lon, lat)

lons = [lon1, lon2, lon3]
lats = [lat1, lat2, lat3]
# assumes numpy imported as np
lons_np = np.array(lons)
lats_np = np.array(lats)

res_list = convertbng_list(lons, lats)
res_list_np = convertbng_list(lons_np, lats_np)
