Plateau Utils

This is a collection of utilities for the Plateau project.

pip install plateauutils

Tested with Python 3.9 and 3.10

CityGML parser

>>> from shapely.geometry import Point
>>> from plateauutils.mesh_geocorder.geo_to_mesh import point_to_meshcode
>>> point = Point(139.71475, 35.70078)
>>> mesh_code = point_to_meshcode(point, "2/1")
>>> mesh_code
'533945471'
>>> from shapely import from_wkt
>>> from plateauutils.parser.city_gml_parser import CityGMLParser
>>> target_polygon = from_wkt("POLYGON ((130.41249721501615 33.224722548534864, 130.41249721501615 33.22506264293093, 130.41621606802997 33.22506264293093, 130.41621606802997 33.224722548534864, 130.41249721501615 33.224722548534864))")
