map-projections

Add geolocalised subsetting, masking, and plotting operations to xarray

GPU and vector-enabled map projections, geodesic calculations, and image warping 🌎🌍🌏

Tools, shapefiles & data to work with an "AlbersUSA" composite projection in R

This is a Java implementation of the Google Maps projection which is based on the mercator projection. You can convert longitude/latitude values to world coordinates and calculate pixel coordinates for different zoom levels.

Native Swift library for drawing map projections

Map projections (under construction)

A Go library for converting between spherical and planar coordinates.

Explore and compare spherical Earth and flat Earth models with real math, flight routes, map projections, and Qibla direction calculations.

QGIS Plugin for map projections distortions visualisation

Interactive celestial map for the browser — a modernised fork of d3-celestial (D3 v7, ES modules, TypeScript types, multiple maps per page)

Lightweight great-circle computation & map-projection library

PyGeodetics is a Python library for performing geodetic computations like geodetic inverse and direct problems, conversions between different reference systems like ECEF to ENU, ECEF to geographic etc.

Interactive web tool for comparing spherical Earth and flat Earth models using distance calculations, flight paths, map projections, and Qibla direction to the Kaaba.

Spatial reference systems and map projections

A high-performance web-based implementation of province map projection using invisible bitmap data layers, inspired by Paradox Interactive games.

Animated morph from Mercator to Equal Earth, built with D3. Made after the UN's Correct the Map vote

R Leaflet

🗺️ Interactive JavaScript maps built on SVG. Choropleth, bubble, marker and arc series, 13 projections, GeoJSON and TopoJSON, and 26 built-in geometry packs.
