Abstract
Abstract. Signed March 24, 1992, the Open Skies Treaty permits each state-party to conduct short-notice, unarmed, reconnaissance flights over the others' entire territories to collect data on military forces and activities. Observation aircraft equipped with sensors shall enable the observing party to identify significant military equipment. The Open Skies Treaty agreed on an observation of 30cm GSD. Based on 8 mid-format cameras for 3 flight levels, a system was adjusted to comply with the regulations. However, the overall aim was to also use the system for mapping purposes in Romania, specifically the medium altitude configuration. From this medium altitude configuration, one specific combination raised our interest. The designed wide corridor mapping system, using two RGB tilted cameras and one RGB nadir camera generates a certain range of resolution of the sideward looking tilted cameras and a non-homogenous distribution of the GSD in the overlapping areas. While a reduction of the GSD in the remote parts of the tilted cameras is a well-known and accepted fact, the effect in the overlap of the tilted cameras with the nadir one is the opposite mathematically. In some cases, such an effect can cause a better GSD in these areas than expected.
Highlights
On March 24 1992, in Helsinki, Finland, the idea of the United States President Dwight D
The original concept, intended to be a bilateral agreement between the United States and the Soviet Union, due to the Canadian Prime Minister Bryan Mulroney and Canadian Secretary of State for External Affairs Joe Clark, has initial turned into a 25 nations aerial observation treaty
Nowadays satellite technologies can collect images with a higher resolution, aerial observations conducted under the force of the Open Skies Treaty gives access at information hard to obtain by all the treaty states-parties and build up confidence between them
Summary
On March 24 1992, in Helsinki, Finland, the idea of the United States President Dwight D. The most important aspect during Open Skies missions is to keep a specific AGL during the observation flights in order not to obtain a better ground resolved distance (GRD) than 30cm referring to the highest point into a leg. An Open Skies mission is defined by segments, legs, observation periods and event IDs. To harmonize the photogrammetric concepts into the Open Skies terms, there was a series of technical decisions that states the terms definitions. There are a lot of similarities with the photogrammetric domain, specific rules are mandatory to be followed by any state member that wants to have a certified platform for Open Skies missions. A Phase One 8 mid-format cameras system, integrated by GGS Germany, was chosen after several technical meetings.
