Khartismade by the médialab

Developed in partnership with Sciences Po’s Atelier de cartographie and APYX, with support from the médialab, Khartis is a free, open-source online tool for easily creating qualitative and quantitative thematic maps from your own data.

Completely redesigned, the new version of Khartis now offers a smoother, guided creation process organised around three stages: Data, Visualisations and Styling. The tool analyses imported data and guides users through their choice of basemaps, data joins, visual representations and map projections.

Khartis supports tabular data in CSV format or copied directly from a spreadsheet, as well as various geographic data formats, including GeoJSON, GeoPackage, Shapefile and GeoParquet. It enables users to create maps that follow the principles of graphic semiology and export them in formats including JPG and SVG.

Local Data Processing

Khartis runs directly in the browser. All data and processing remain local: no imported files are transmitted to or stored on an external server.

Thanks to Progressive Web App (PWA) technology, Khartis can also be installed directly from the browser and used offline.

An Open-Source Tool

Free and open source, Khartis is released under the MIT licence, and its source code is available on GitHub. The tool can be freely used for academic, educational, journalistic, professional or personal projects.

Educational resources and detailed documentation are also available to help users get started with Khartis, from creating their first map to using more advanced features.
