Tree planting director for Casey Trees uses a Global Positioning Satellite (GPS) enabled tablet computer to review the precise locations of 100 trees planted at Joint Base Anacostia-Bolling (JBAB) starting on Earth Day 2014, April 22. The GPS positioning and barcode information for each tree enables JBAB's Public Works department to enter the precise location of each tree planted during April and May 2014 at the military installation into the public works' Geographical Information System (GIS) for tree maintenance and future land use planning.
