By 2020, the subsea sector of oil exploration and extraction is expected to account for 20% of total crude oil production. In addition, global marine ? sheries, which provide 15% of all animal protein consumed by humans, have been steadily collapsing for the last half century.

allowing aerial photographic observation to become more Esri has just released the Drone2Map for ArcGIS app, which accessible at a fraction of the cost of chartering aircraft for transforms high-resolution drone imagery into ready-to-use the same purpose. Fuel expenses alone can be an obstacle to aerial data in the GIS platform. Users can bring point-clouds, obtaining aerial data. Drone integration with geographic in- mosaic datasets, 3D meshes and orthomosaics directly into formation system (GIS) technologies has existed for several the platform in near real time without any third-party applica- years. Using drones has proved to be a cost-effective and safe tion. This is a huge leap in hydrographic technology because way to collect aerial data, with applications commonly used users can instantly produce new observations to update nauti- for ? ghting ? re, monitoring environmental changes and man- cal charts and topographic maps. Simple photographic data aging rights-of-way vegetation. However, when users bring obtained from a miniature camera mounted on a drone can be drone data into GIS, they exponentially increase the value of used for point-cloud collection, rather than rely on airborne that data. And thanks to new innovations in drone technology, lidar. Additionally, a geospatial platform stores and manages maritime users can exploit that integration in new and exciting Drone2Map data, provides authoring and publishing tools and ways. A seamless topobathymetric surface is now available to streams live and authoritative data for rich situational aware-
