Abstract
A GPS receiving apparatus is equipped with a GPS receiver 10, a data decoder 12, data memory means 14, a CPU 16, a display 18 and an input pen 20. The display 18 is provided with a digitizing function to allow input by drawing of data with the input pen 20. A sky diagram image 24 serving as the input screen consists of a circular figure the perimeter of which represents the horizon and the center of which is considered as the zenith, and after the observer aligns the sky diagram image 24 with the observation point, the input pen 20 is used to draw images (a), (b) and (c) of the shape of and the proportion of sky occupied by obstacles such as buildings, trees and mountains within the field of view of the area based on the elevation angle of the observer himself, and the images are incorporated into the CPU 16 as obstacle-related data.
