COMPUTER AUTOMATED SYSTEM AND METHOD FOR CONVERTING SOURCE DOCUMENTS BEARING ALPHANUMERIC TEXT RELATING TO SURVEY MEASUREMENTS

摘要

The computer automated system and method (100) of converting an image file of a scanned source document (206), bearing alphanumeric text relating to the lengths and directions of the bounding lines of an area surveyed, into a mathematically accurate vector computer drawing file based on that alphanumeric text. The digitized image file (1.0) is imported into an existing CAD system having a COGO subroutine (3.0) and using an OCR (2.0) operating within the CAD system. The method provides a quality control check of source documents by disclosing the closure of the bounding lines and superposing the vector drawing over any originally scanned drawing image.
