What is Graticule

Graticule is a browser-based tool for building and editing maps. Graticule is under active development, and currently focuses on editing and styling vector data.

Graticule is not a replacement for QGIS, Mapshaper, or GDAL. It aims to provide a superior user experience for common techniques and workflows for producing maps, but experienced GIS experts may find it lacking in the power that more mature tools provide. But if you are a dataviz professional, journalist, designer, or map enthusiast who just wants a quick and joyful experience making a nice map, you may enjoy Graticule.

Principles

Nothing leaves your machine. Graticule runs entirely in the browser — no account, no server, no data collection.

File-over-app. Projects save as plain .json files you own.

Non-destructive. Operations are applied on top of the stored data. The underlying geometry is never modified, so you can always change settings or undo an action.

Quickstart

1. Add data — browse the catalog, or upload a GeoJSON, Shapefile, KML, CSV, or other file.
2. Project — choose from 80+ projections.
3. Style — per-layer fill, stroke, simplification, and smoothing controls.
4. Select and edit — switch to Select mode (S) to pick layers or drill into individual features. Use the action bar to dissolve, clip, subtract, explode, or merge geometry.
5. Export — SVG or PNG. Save a project file to resume later.
