Shapely Compute

A clean wrapper around Shapely for computational geometry tasks. Use it when you need to check if a point falls inside a polygon, calculate intersection areas, find distances between shapes, or do buffer operations. Covers the essentials: boolean operations like union and difference, spatial predicates like contains and intersects, measurements like area and centroid, plus affine transformations. Everything returns JSON with WKT representations, so you can pipe results between operations. The command structure is sensible: create geometries from coordinates, run ops on them, test predicates, measure properties. Honestly most useful for spatial analysis tasks where you'd otherwise be writing boilerplate Shapely code yourself.

Computational Geometry with Shapely

When to Use

Creating geometric shapes (points, lines, polygons)
Boolean operations (intersection, union, difference)
Spatial predicates (contains, intersects, within)
Measurements (area, length, distance, centroid)
Geometry transformations (translate, rotate, scale)
Validating and fixing invalid geometries

Quick Reference

I want to...	Command	Example
Create geometry	`create`	`create polygon --coords "0,0 1,0 1,1 0,1"`
Intersection	`op intersection`	`op intersection --g1 "POLYGON(...)" --g2 "POLYGON(...)"`
Check contains	`pred contains`	`pred contains --g1 "POLYGON(...)" --g2 "POINT(0.5 0.5)"`
Calculate area	`measure area`	`measure area --geom "POLYGON(...)"`
Distance	`distance`	`distance --g1 "POINT(0 0)" --g2 "POINT(3 4)"`
Transform	`transform translate`	`transform translate --geom "..." --params "1,2"`
Validate	`validate`	`validate --geom "POLYGON(...)"`
