First, preparation work 1, install the plug-inTo facilitate drawing, we have installed OPENLAYERS,QUICKOSM two plugins.How to install plug-ins, degrees Niang have the answer. Part of the tick is the installed plug-in:Openlayers provides some open map data, and with this data, we don't have to start all over again, like Bing's satellite map, we can accurately plot the desired line, point, and multilateral type from satellite maps.
