WebbTableCrow. tablecrow is an abstraction over a generalized database table. Currently, tablecrow offers an abstraction for PostGreSQL and SQLite tables with simple PostGIS and SpatiaLite operations. pip install tablecrow Data Model. tablecrow sees a database schema as a mapping of field names to Python types, and a database record / row as a mapping … WebbShapely geometries are, by design, agnostic (unaware) of the reference system used to represent them. Distances and surface area calculated using the built-in shapely methods will always: a) assume a flat, Cartesian, Euclidean space, and b) return the calculated value in the unit of the coordinates (e.g., meters, or degrees).
