Cythonized geodetic and planar distance functions for R-Trees.
Project description
boxdist
Cythonized geodetic and planar distance functions for R-Trees. The implementation is adapted from Tile38, which is based on the paper Geodetic Distance Queries on R-Trees for Indexing Geographic Data.
Geodetic
from boxdist import geodetic_box_dist
targetlon = -72.946472
targetlat = 45.154927
minlon = -74.19342
minlat = 45.265222
maxlon = -73.157959
maxlat = 45.704261
meters = geodetic_box_dist(
targetlon,
targetlat,
minlon,
minlat,
maxlon,
maxlat,
)
meters #=> 20612.892322138163
Planar
from boxdist import planar_box_dist
targetx = 0
targety = 0
minx = 1
miny = 1
maxx = 2
maxy = 2
squared_dist = planar_box_dist(
targetx,
targety,
minx,
miny,
maxx,
maxy,
)
squared_dist #=> 2
