Magrit - Thematic cartography

Magrit - Banner

[en] Magrit is an online thematic mapping application developed by UAR RIATE.
[fr] Magrit est une application de cartographie thématique développée par l'UAR RIATE.

Basics

Magrit is a web application for thematic mapping (cartography).
Everything happens in the browser, so your data never leaves your computer.
It's intentionally simple (the UI follows the basic steps of map creation).
It's designed for teaching and learning cartography.
It lets you import your own geometry dataset (Shapefile, GeoJSON, GML, GeoPackage, etc.) and optionally your tabular file (CSV, XLS, XLSX, etc.).
We also provide many sample datasets to try out the various representations and become familiar with the application.
It allows you to render and combine a wide variety of maps: choropleth, proportional symbols, cartogram, discontinuity, smoothed maps, links, etc.
It allows you to customize the appearance of your maps in various ways.
It supports all the most popular modern desktop browsers.
Magrit is written in modern JS and uses notably solid.js and d3.js libraries as well as various WebAssembly modules (GDAL, GEOS, Contour-wasm, go-cart-wasm).
