ABSTRACT:
A method for interactive contouring of seismic data for procuring seismic maps (60a, 60b, 60c) which provide a three-dimensional picture of the various structural layers (5a-5n, 12a-12n, respectively) within an area (11) which is circumscribed by intersecting shooting lines (6a-6d). In order to achieve a shorter processing time for procuring such maps, the data representing the individual structural layers (5a-5n) referred to a fixed reference line (2a) are procured as a color coded echo line (12h) on a graphic data screen (22), the indication of depth being given as a color value in relation to a preselected color scale (40). The interpreter can insert between the various points having the same color value on the echo line (12h) fresh interpreted values in the same grid according to the same color code, so that for each structural layer (5a-5n, 12a-12n, respectively) there can be provided a mapping (60a-60n) having surface adaptations given in various color values directly on the screen (22). The graphic display of the structural layer maps can be reproduced three-dimensionally on a color value printer (31) directly from the screen (22).
