Abstract
Operational software has been :developed for mapping from SPOT satellite analogue images on the Wild Aviolyt BC2 analytical plotter. The software is designed to reflect as nearly as possible standard BC2 software procedures. The solution of the scanner geometry is based on a rigorous collinearity formulation with the position and tilts varying according to first or second order polynomials. Satellite ephemenis data are used to provide estimates of the polynomial parameters. Coordinate transformations will enable the plotting and computation of coordinates in a local projection system on the analytical plotter in a mapping environment. Precision of computation of object coordinates have been shown to be of the order of 5-10m in planimetry and height coordinates depending on the precision of ground control points.
