1. A method comprising:
- displaying a contour map to a user on a display of an electronic device, the contour map being rendered by a processor of the electronic device from a union of static contours and dynamic contours, the static contours and the dynamic contours representing specific elevations, wherein the static contours comprise elevation lines derived from a vector source database and the dynamic contours comprise elevation lines derived from a parameter source database that enables user-selection of a drawing of elevation lines according to parameters selected by the user; and
setting a visible property of the dynamic contours to make the dynamic contours visible or invisible, wherein when the dynamic contours are visible the dynamic contours are displayed simultaneously with the static contours on the contour map, and when the dynamic contours are invisible the dynamic contours are not displayed on the contour map and the dynamic contours are used for three dimensional rendering and vertical profiling in the contour map.
