The article
In the article I read the companies senseFly and Drone Adventures collaborated to create several drones, called eBees, that were able to work together and autonomously map the the entire Matterhorn mountain on the border between Switzerland and Italy in less than a day. The drones are able to create seamless maps. The drones are able to do their own 3D flight planning so using them is a simple as picking an area for the drones to map and launching them.
Future implications
The primary application of these drones would be in surveying land. There are also possible applications in military use. These drones could be modified to survey an area and mark points of interest for soldiers.
