1. A computer method of converting an alphanumeric text relating to a length and a direction of a bounding line of an area surveyed from a hard copy source document into a mathematically accurate vector, said method comprising the steps of:

  • (a) receiving digitized output from an automated digitizing unit into a CAD applications program in a computer, said output comprising alphanumeric text relating to a length and a direction of a bounding line of an area surveyed, and in a format usable by said CAD applications program, said CAD applications program including a coordinate geometry subroutine, said alphanumeric text having been scanned from said hard copy source document;

    (b) recognizing said alphanumerical text in an optical character recognition subroutine operating in said CAD applications program;

    (c) transporting said alphanumeric text from step (b) in a format usable by said coordinate geometry subroutine into said coordinate geometry subroutine; and

    (d) converting said alphanumeric text from step (c) into a mathematically accurate vector, said vector having an orientation and a distance corresponding to the length and the direction of said bounding line of the area surveyed, said vector also having a beginning point coordinate and an endpoint coordinate.
