yields. To grant the agricultural subsidy it had to record the 
cultivation data of the area too. On the basis of field works new 
digital soil and nutriment supply maps were created to evaluate 
agri-ecological environment. Digital elevation model with 1 m 
vertical and 0.2 m horizontal RMS was produced. 
In the course of the field works every stock place in the pear 
genetic collection were measured by DGPS methods, where the 
survey accuracy was RMS<0.2 m after the TRIMBLE 
PATHFINDER compensating calculation in Geostation 
environment. The height and width of trees were defined with 
the help of Leica Distro 8 laser distance meter. To prepare the 
hyperspectral flight we used a digital orthophoto, which was 
taken in 2007 with a ground resolution of 0.5*0.5 m. 
The spatial data were completed by airborne hyperspectral data, 
which in general makes possible to perform botanical and 
special soil investigations (Nagy et al, 2006). 
Since the applied joint camera is less known in Europe and it 
can also be reached as an investigation delivery, the details of 
the measurement are described below. 
In 2007, the first high-tech AISA DUAL airborne hyperspectral 
image spectroscopy system (AIS) was installed and operated in 
cooperation the University of Debrecen, AMTC, Department of 
Water and Environmental Management with the Hungarian 
Institute of Agricultural Engineering in Godollo-Hungary 
funded by NKTH. The most important parts of the hyperspectral 
sensors are the spectrograph, which dissolve the electric waves 
arrived through the optical rift with the help of prisms and 
optical screen. The two hyperspectral sensors are mounted and 
synchronized in a common house; therefore it is known ASIA 
DUAL system (Milics et al. 2010). 
The two cams can perceive in the visible wavelength, near 
infrared range and short wave infrared range. Technical 
information of applied ASIA DUAL hyperspectral system as 
follows: Push-broom hyperspectral imagery sensor with the 
fibre optic radiation meters (FODIS); Miniature integrated 
GPS/INS sensor, which serves the position, height and 
momentary situation (pith, roll, yaw) of plane, Compact PC- 
based data collector and mobile receiver unit; CaliGeo software 
runs as a separate software package under the ITT ENVI 
software package to do the spectral and geometrical corrections. 
The parameters of the hyperspectral image: Wavelength: 400- 
2450 nm (EAGLE: 400-970 nm and HAWK: 970-2450 nm); 
Spectral sample taking: 1,2-10 nm; Ground resolution: 0,4-3 m 
(with plane flight altitude), The photogrammetric and spectral 
accuracies were evaluated by different GPS/Inertia systems in 
different flight conditions in Europe (Germany, Finland, 
Switzerland and Hungary) in 2008-2009. 
OxTS - RT 3003 was showed pixel sized accuracy of lm 
without external DGPS data while the C-MIGITS III provided 
about 6m RMS position error, when the average flight altitude 
was 800-1000 m and the average speed was 200-250 km/h, with 
minimum swath width of 500m. Studying the navigation data it 
can be determinable that the angle deflection of the flight 
remains within 10 degree in case of taking image in general 
climatic conditions (Table 1.). However in special 
meteorological condition we also measured larger deflections 
rates, which was rarely exceeded 15 %.

Table 1. Flight parameters 
The hyperspectral DUAL sensor is fixed without gyrostabilizer 
in the airplane, so the deflection originating from the motion of 
the airplane is corrected by CALIGEO program with the 
navigation data of GPS/INS system in the course of the 
geometric correction. Before the flight boresight type 
calibration was carried out (Holzwarth et al., 2005). 
The images of the flight campaign using in this paper were 
taken in the early afternoon in cloudless condition in June 2009, 
where the mean angle deflection was lower than 4%. 
Before mosaicing of the images parametrical correction and 
radiometrical normalization between the bands were applied 
(Burai and Tamas, 2004) (Figure 1.).

and the Ujfeherto Research Station (red border lines) 
The accurate geometrical correction of the hyperspectral image 
taken by AISA DUAL push-broom sensor with high spatial 
resolution (<1.5 m) could be achieved by OxTS RT 3003 
positioning system working with two antenna. The 
atmospherical correction was done on the basis of the direct 
radiation measured by FODIS sensor detecting the changing of 
the radiation above the sensor. We modified the effects from the 
movements of the airplane with the navigation values, which is 
necessary to define the FODIS ratio. The high angle deflection 
values were separated from the FODIS data, which was 
replaced by data generated linear interpolation.
