Python shapely wkt
http://www.duoduokou.com/python/27195581515852849089.html WebGeometric objects in any Python package (e.g. GDAL, shapely) are usually based on the geometries that can be represented in WKT strings. As such, it is useful to know how to write geometries in WKT; then you do not need to learn the specific way of each individual Python package. GDAL (OGR) example: Python source

Webpolygon: A shapely.Polygon where to put the Cbsd. nlcd_driver: The land cover driver for detecting inland positions (optional). urban_areas: An optional shapely.MultiPolygon defining the urban areas. If not specified, do not enforce the Cbsd to be in urban areas. WebGeometries can be used as elements in sets or as keys in dictionaries. Python uses a technique called hashing for lookups in these datastructures. Shapely generates this hash from the WKB representation. Therefore, geometries are equal if and only if their WKB representations are equal.
WebShapely Shapely was mentioned in the WKT section for import and export ability. But its true purpose is a generic geometry library. Shapely is a high-level, pythonic interface to the GEOS library for geometric operations. In fact, Shapely intentionally avoids reading or writing files.
