Abstract: A method and system for allocating parcels of land property located on a planetary body such as the Moon, such parcels being sub-divisions of extensive parts of land on the planetary body that have previously been subjected to government sponsored manned spacecraft landings and the subsequent site explorations and surveys. Such explorations, when survey-referenced to well-defined manned-spacecraft landing sites, provide the potential for a government to claim extensive parts of land and subsequently exercise an option to grant parcels to individuals for the purpose of encouraging government-beneficial land development. The availability of manned-landing site survey reference points enables sub-division of the land into parcels whose individual locations and boundaries can be precisely defined in a land grant.

Abstract: An apparatus for determining distance coordinates along two orthogonal axes for a computer system, where the coordinates represent the position of a cursor on a screen of a display unit of the computer system. The apparatus includes a pair of velocity detectors and an operating device such as a CPU. When the velocity detectors are moved by an operator, each of the velocity detectors detects velocities along a respective one of the orthogonal axes. The detected velocities are converted into moving distances representative of the coordinates through a calculation of the operating device.
