A Computer Oriented Geodetic Data Base and a New Technique in File Sequencing

A coordinate system for use with map or survey data is introduced and developed. Although this system can be applied to any sized area on any part of the Earth's surface, particular reference is made to Canada. The problems of using data spanning such a large area are discussed, and a new technique of file sequencing is introduced to counter these problems. Some of the properties of such a file sequence are used to demonstrate the flexibility and power to be gained by use of this technique.
