This set up limits the ability to compare like-to-like environmental impact and services between the impact and the compensation. A few attempts have been made to use geographic data systems to map precise project locations and track progress of existing and completed projects, for instance by including the co-ordinates of a selection of compensation projects in Google Earth (Garcia, 2014). While this approach would not by itself replace the need to carry out inspections on site, it could allow building a database or registry of compensated areas to aid in the evaluation of the programme effectiveness in the future.
