The first GPS photogrammetry system has been used in Iran by 
NCC within its Jet Falcon 20 aircraft for 1:40000 aerial 
photography projects in the year 2000. This system 
accompanying with bundle aerial triangulation method were a 
great help to NCC to accomplish the task of preparing 1:25000 
base map for remote and desert area of country. Due to some 
problems, it is decided not to use this system for large scale 
mapping projects. 
In 2003 a comprehensive study on Direct Geo-referencing 
systems using GPS/IMU observation took place in NCC and 
negotiations with one of system providers were started. 
According to this, the basic approval for utilizing these systems 
in large scale photographic projects has been made and as soon 
as clearing a few technical details, the purchase process will be 
started. 
Recently, after a serious decision for use of digital aerial 
triangulation system followed by comprehensive study on 
available systems, one of them which is develop by an Iranian 
company has been selected and it is expected to be installed in 
NCC within a few months. Note that, traditionally almost entire 
aerial triangulation process of civil mapping projects in Iran are 
executed by NCC. 
Beside all these efforts, a preliminary study on upgrading 
imaging systems has been started and it is expected to equip our 
aerial photography fleet with digital aerial camera and/or new 
imaging sensors such as LIDAR within the next 5 years. 
4.4 Use of Space Technology 
With advent of new satellite technology and vast amount of 
high resolution satellite imageries, in addition to rapid 
development of remote sensing activities, one can observe a 
serious impact to photogrammetry discipline. Beside many 
activities for using these images for mapping purposes in the 
country (some of them were mentioned earlier in this report), 
recently NCC has finished a project to evaluate the potential of 
new 2.5m SPOT HRG imageries for updating 1:25000 digital 
base maps of the country. The final results have shown the 
capability of these imageries and practical use of them can be 
started as soon as possible.
