Calculates the WGS84 great-circle distance and initial bearing between two geographic coordinates

Converts WGS84 latitude/longitude coordinates to Military Grid Reference System (MGRS) notation using the open mgrs library, with configurable precision.

Encodes a WGS84 coordinate into a geohash string at a specified precision, or decodes a geohash string back to its bounding box.

Tests whether a planar 2D point lies inside a polygon using the even-odd rule, returning a boolean containment result.

Calculates the planar area and centroid of a polygon defined by a sequence of (x, y) coordinate pairs in caller-declared units

Converts a geographic coordinate (lat/lon) and S2 level to an S2 cell token using the S2 geometry library

Enumerates all XYZ tile coordinates (z/x/y) that intersect a given WGS84 bounding box at a specified zoom level

Creates H3 cells from coordinates, finds neighbors, or changes cell resolution using Uber's H3 hierarchical hexagonal geospatial indexing system

Simplifies a planar polyline using the Ramer-Douglas-Peucker algorithm, reducing point count while preserving shape within a given tolerance.

Converts geographic coordinates between EPSG:4326 (WGS84 lat/lon) and EPSG:3857 (Web Mercator) using declared formulas
