Keystone was the first company in the United States to take delivery of the Ultracam Eagle. UCE features an ultra large image size of 260 megapixel (20,010 x 13,080 pixels) and has a pixel size of 5.2 microns. The larger image size allows Keystone to acquire the same GSD at higher altitudes providing coverage with fewer flight lines thus reducing overall project cost. With the 80mm lens installed, the UCE has a base to height ratio of 0.34, making it the best digital camera on the market for mapping applications. UCE is lightweight, allowing flight crews to carry more fuel and extend acquisition time over the project to take advantage of optimal flight conditions. Data storage is on solid-state hard drives allowing for increased reliability and extremely fast data transfer rates up to 3.7 gigabits per second allow for fast                                                                           recovery times between images. UltraCam Eagle specifications.

The large 136 megapixel image size (14,430 x 9,420 pixels) combined with small pixel size of 7.2 microns and high geometric accuracy of about 2 microns makes the UCX ideally suited for efficient collection of high-resolution imagery for mapping applications. Three UCX systems give Keystone system redundancy and the ability to rapidly acquire large projects by simultaneously deploying multiple UCX systems. Removable data storage units can be exchanged in flight when they are at maximum capacity and are pressure sealed for high altitude operations in unpressurized cabins. UltraCam X specifications

The Optech Gemini excels at both high and low altitude scanning. It provides Keystone the ability to operate in both large scale block jobs as well as small corridors. With the additions of both multipulse technology and the ability to collect high density areas, Keystone is able to tailor jobs to any client specifications.
