ViewGL is a downloadable program developed by Aerials Express that provides updated aerial photography content through Google Earth. The development of ViewGL reflects a core issue confronting Google Earth's mission to accurately represent the planet Earth: data management. As of now, Google Earth is a patch-work of satellite and airborne imagery from various sources. Maintaining the accuracy and currency of this data for the United States, let alone the entire planet, is a daunting task. This results in significant portions of the Google Earth photography being outdated, having a tiled appearance, containing clouds, and being poorly projected. Consequently ViewGL has specialized in supplying the most current aerial imagery of US metropolitan areas possible, resulting in higher temporal accuracy.
