For use in a map database, a method of capturing the linear features along a reference line across the surface

摘要

[Challenge] [MEANS FOR SOLVING PROBLEMS] For use in a map database, of creating linear features along a reference line across the surface is disclosed. The reference line data representing the coordinates of the reference line in the geographic coordinate reference system, and the source image of the surface adjacent to the reference line, the method, reference line reference data from the attitude data and associated position in the geographic coordinate reference system and generating a set, for use in a map database, and a step of post-processing the baseline reference data set to create the associated location in the geographic coordinate reference system and linear features along the reference line, the reference The line reference data set, and a related data that defines the reference line across the surface in a geographic coordinate reference system and the plurality of sets of image data having a pixel, a set of image data of the line section parts of the surface in the geographic coordinate reference system represents a surface having a position corresponding to the orthorectified diagram representation includes a reference pixel of each set of image data is associated with the position of the reference line, is present at a predetermined distance from the position of the reference pixel to each pixel along the line section minutes and intersects perpendicular to the reference line at the position where the line section component is associated with the reference pixel.
