JOSM is an extensible editor for ​OpenStreetMap (OSM) data.
Some notable features of JOSM are importing GPX files (GPS tracks), working with aerial imagery (including WMS, TMS and WMTS protocols), support for multiple cartographic projections, layers, relations editing, data validation tools, data filtering, offline work, presets and rendering styles. JOSM provides more than 200 keyboard shortcuts for the core functions.
Many additional features (like tools for drawing buildings, adding Wikipedia links or viewing data in 3D) are available through the plugins. There are more than 100 of them in the repository.
Does not work in rollApp: asks to update Java... which is supposed to be on the server! (But that does not say anything about JSOM itself)
Very nice!
Cannot edit from remote server task osm.
Thanks its useful
