Mapzap

Build custom responsive web mapping applications without any coding!

A simple, lightweight tool for quickly standing up responsive web mapping applications (mapzaps) without having to write any code. Built on the Google Maps JavaScript API, this utility lets you configure your settings via simple URL parameters. Feed it a source data file in GeoJSON format (or CSV with latitude & longitude columns), give it a title, icon, and tell it which data fields you want to show, and you get a responsive, mobile-friendly "mapzap" for viewing and interacting with your data. Your mapzap can be shared, embedded into websites and blogs, and added to your mobile device's homescreen for a native, full screen experience. Use geojson.io, GeoEditor, Fulcrum, QGIS or any other modern mapping tool to generate your GeoJSON, place it on a web server, push it to GitHub, Google Drive, Dropbox, etc. or save it as a Gist and quickly wrap it up as a responsive web app.
