The improved dataset should be further treated to minimize inherent errors and fitting to the new accurate dataset. However, by merely integrating both datasets will lead to a distortion of the relative geometry. Integration of legacy dataset and higher accuracy dataset like GNSS observation is a potential solution for improving the legacy dataset. With the growth of spatial based technology especially Geographical Information System (GIS) and Global Navigation Satellite System (GNSS), the PAI campaign is inevitable especially to the legacy cadastral database. This actual position relates to the absolute position in specific coordinate system and the relation to the neighborhood features. Positional Accuracy Improvement (PAI) is the refining process of the geometry feature in a geospatial dataset to improve its actual position. The attitude determination error of a satellite still restricts its positioning accuracy.Ĭadastral Database Positional Accuracy Improvement Precise simulation calculations show that image positioning accuracy of super low altitude remote sensing satellites is not obviously improved. These parameters include: orbit determination accuracy, attitude determination accuracy, camera exposure time, accurately synchronizing the reception of ephemeris with attitude data, geometric calibration and precise orbit verification. The exact line-of-sight rebuilding of each detection element and this direction precisely intersecting with the Earth's elliptical when the camera on the satellite is imaging are both ensured by the combined design of key parameters. The use of engineering data in design for achieving image positioning accuracy is discussed in this paper based on the principles of the photogrammetry theory.
