Manufacturing system for numerical map

摘要

PURPOSE: A high precision numerical map manufacturing system using the synthesis of GPS and numerical data is provided to enable an amateur to easily install and remove a reference point display device. CONSTITUTION: A ground image collector(100) is installed in an aircraft. A plurality of reference point display devices(200,200',200") is installed in one spot corresponding to the reference point of the ground. A numerical map drawing device(300) edits the aviation photographing image supplied from the ground image collector and completes the numerical map through the input of the numerical information.
