Map Your Lawn

Map Your Lawn Webapp
Simple GeoJSON editor with freehand drawing 

Look up your property, mark out areas and cut off all unnecessary to have your area in feet, yards, meters and others. You can also open and add GeoJSON shapes to the map from your local computer or with a direct link to a Web resource. Save the result as GeoJSON for future reference (with a subscription). Try our Map Your Lawn webapp today! See our Privacy Policy.

Important note! Until the issue with using a google script app in a multiuser environment (signed-in in one session) is resolved, use this web app with one only signed-in Google account. You can also use it in the private mode tab.

For developers:

Embed this app into your site with your own Google Maps API Key with enabled Maps JavaScript API. You can customize the appearance of the map and use callback functions to integrate it with your page or application.
