Extension professionals need geospatial and remote sensing solutions that meet their varied needs; however, training time and funding for expensive software packages can be limited. Google Earth is a freely available, user-friendly GIS that can meet many of the day-to-day needs of Extension professionals by providing high-quality current and historical aerial photography, length and area measurement tools, GPS integration, and simple mapping capabilities. Third-party add-ons can increase the somewhat limited capabilities of Google Earth. Google Earth's general accessibility also lends itself to innovative, collaborative uses with clients, youth, and the general public.
