Frequently Asked Questions - Lines and Areas (in Beta Version)


On the Open Green Map, you can chart lines (routes) and areas (polygons) to represent paths such as bike routes or walking tours and areas such as parks or hazardous areas.

The Mapmaker can enable these on the Map Edit form. If they have done so, the Legend shows all the different types. You can hover over each color for the definition. Click on a line or area on the map for its info-window. You can add to the info-window by opening 'more info' then select tabs for comments, ratings, or under Multimedia, add a photo or video, too.
