Processing of aerogeophysical data by PERICOLOR image processing system

The results of the last stage of an aerogeophysical survey are available on computer compatible tapes in Czechoslovakia. For the processing and interpretation, the image processing system PERICOLOR is used. In the case of aeromagnetic data, the best results are obtained by means of directional first-derivative filtering. On the other hand, with aerospectrometric data, the plotting in the form of colour composite images and ternary maps is the best way. Simultaneous presentation of different data is possible using the HSI transform. Multiple data sets (including topography and gravity) are prepared for integral processing and interpretation in some parts of Czechoslovakia.
