International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Vol XXXV, Part B-YF. Istanbul 2004 For the vertical accuracy the type was verified (0.412m<1.8m and as it was expected. The type was also verified for the horizontal accuracy (1.245m>1.8m), a fact that indicates that the orthoimage’s accuracy is bearable according to the technical specifications of Hellenic Cadastre. 4.3. Orthoimage’s accuracy estimation of that was produced with the method of GPS In this method eight points were used for the control precision, which were measured, as mentioned above, with GPS. In this method it was calculated that 6,,,=0.505m and 6,,=0.370m for the eight points. The reliability control for gross errors in the nine control points accomplished successfully. There was no necessity to reject any point because of the type below: OX; , óy; € 1.96 Opor = 0.99m (11) As well as the type: 02;<2.16 6,,= 0.779m (12) Continuously a total accuracy control was applied, where the following type should be verified: Ohr 5 0.920xy = 090 (13) And the type 640.986, = 0.967 (14) The type for the vertical accuracy (0.370m<1.8m) was verified as well as the type for the horizontal accuracy (0.505m>1.8m), fact that indicates that the orthoimage’s accuracy is_bearable according to the technical specifications of Hellenic Cadastre. 5. CONCLUSION Underlining the more important points of this research, in regard to the possibility of application of panchromatic image of satellite IKONOS -2 in the Hellenic Cadastre, judged necessary the report of the following conclusions and proposals: 5.1. First method From the panchromatic orthoimage control resulted an estimation of total horizontal error equal to 1.245 m while the technical specifications of Hellenic Cadastre for suburban region (1:5000) is 2m. Obviously the accuracy from the orthoimage is acceptable from the Hellenic Cadastre. The proposal that can be formulated for this method, in order to be the orthoimage production possible in Cadastral applications is the following: digitization of cartographic maps in bigger 166 scale (for example 1:1000), with a recent syntax (ideal date 2000, for the particular application, because this is the chronology of image reception). 5.2. Second method From the panchromatic orthoimage control resulted an estimation of total horizontal error equal to 0,505m while the tolerance given by the technical specifications of Hellenic Cadastre for this particular region (1:5000) is 2m. We lead to the conclusion that is possible to use this orthoimage in the Hellenic Cadastre. Provided that this method became acceptable from the technical specifications of the Hellenic Cadastre, the only proposition that can be suggested is: Measurements of as many as possible characteristic points (for this region at least 100), aiming at the simultaneous production of digital terrain model (DTM), with the “stop and go” method. The method “stop and go” provides accuracy "unacceptable" for the GPS specifications (0.5m) but acceptable accuracy for the particular application with simultaneous production of digital terrain model (Pikridas C., 2001) (Christodoulou K., 2002). 6.
