Ship drawing and editing to users who are not GIS specialists. Shapes snap into place, neighbours stay connected and undo always works.
vectorstream is a geometry editor that product teams embed in their own web map, on Leaflet, OpenLayers or MapLibre GL. It gives end users drawing tools for points, lines, polygons, rectangles, circles and text, plus editing that keeps neighbouring shapes connected through shared borders. Undo is exact, documents are saved automatically in the browser, and the product reads every result back as GeoJSON.
Use cases
Users of a scheduling, booking or field-service app want to mark an area, not learn GIS. Snapping, docking when a shape is moved and a forgiving undo make that safe for them.
Many products divide space between users, teams or time slots: delivery zones, territories, plots. Shared borders let a user adjust one line without creating a gap or a strip covered twice.
Users work on the same map over several days. Several documents are saved automatically in the browser, and a layer tree keeps larger projects in order.
Why topology
Keeping shared borders consistent through split, union, cut and undo is a large engineering project on its own. vectorstream ships that core, so your team can work on the product around it.
Adapters for Leaflet, OpenLayers and MapLibre GL run the same core. A product can move to another map library later and keep the editing behaviour its users already know.
Everything goes in and out as GeoJSON. Your backend stores features the way it already does, with an open format between the editor and your database.
How it works
Choose the adapter for the map library your product already renders with.
Pass the user's existing shapes in as GeoJSON.
Users draw, snap, split and undo inside your own interface.
Read changes back as GeoJSON and save them with your product's own records.
