Claim 4:
5. The system of claim 1, wherein the instructions are executable to map the position of the electronic mobile device with respect to the segment via one or both of interpolation and extrapolation such that, the georeferenceable points have respective image points on the navigational chart, the image points having image X-Y coordinates that define their location on the navigational chart;
via interpolation the segment between two image points on the navigational chart is generated as a linear interpolant; via extrapolation, an image point lying outside a domain of the linear interpolant is determined; and
by using the interpolant as a basis and via extrapolation, the system maps the position of the mobile device on the navigational chart with respect to the segment that was generated as the linear interpolant.
