With this integrated approach, we can not only supplement traditional monitoring methodologies, we can produce precise vegetation maps at scales and speeds that we couldn't ever imagine or do as human interpreters." — Whitney Broussard, Senior Scientist, JESCO Broussard exported the classifications as shapefiles and used ArcGIS to finalize the cartography and perform a spatial analysis, calculating the percent coverage for each of the vegetation types and for land versus water. Based on a comparative analysis with local authority data, he identified 100 percent of the vegetation types, calculated plant heights to within 80-90 percent, and produced a "strikingly more detailed" land-water interface map. In the spring of 2017, Broussard presented the maps to local authorities who expressed interest in incorporating a UAS-based method into their traditional monitoring campaigns. More validation of the new approach came only a few months after completing the Terrebonne Parish project, when JESCO was tasked to use their UAS-OBIA solution to survey and classify a wetlands mitigation bank at Louisiana's Rockefeller Wildlife Refuge. More combined UAS-OBIA survey assignments have followed. Based on the successes of this integrated application, it appears that a new vegetation-mapping business has taken flight.
