pyGeoTile 1.0.6

Python package to handle tiles and points of different projections, in particular WGS 84 (Latitude, Longitude), Spherical Mercator (Meters), Pixel Pyramid and Tiles (TMS, Google, QuadTree)

Usage

The package pyGeoTile consist of two main classes, namely Point and Tile. As already mentioned they allow you to convert various geo projections. The full API documentation could be found under http://pygeotile.readthedocs.io

Point

Example of the class Point.

from pygeotile.point import Point

meter_x, meter_y, zoom = -9757148.442088600, 5138517.444985110, 19  # meters in Spherical Mercator EPSG:900913

point = Point.from_meters(meter_x=meter_x, meter_y=meter_y)

print('Pixels: ', point.pixels(zoom=zoom))  # Pixels:  (34430592, 49899136)
print('Lat/Lon: ', point.latitude_longitude)  # Lat/Lon:  (41.84987190947754, -87.64995574951166)

Tile

Example of the class Tile.

from pygeotile.tile import Tile

tms_x, tms_y, zoom = 134494, 329369, 19
tile = Tile.from_tms(tms_x=tms_x, tms_y=tms_y, zoom=19)  # Tile Map Service (TMS) X Y and zoom

print('QuadTree: ', tile.quad_tree)  # QuadTree:  0302222310303211330
