SCANIT: Centralized Digitizing of Forest Resource Maps or Photographs

摘要

Spatial data on wildland resource maps and aerial photographs can be analyzed by computer after digitizing. SCANIT is a computerized system for encoding such data in digital form. The system, consisting of a collection of computer programs and subroutines, provides a powerful and versatile tool for a variety of resource analyses. SCANIT can also be converted easily to another computer system. As a highly automated system, SCANIT requires a substantial investment in specialized instruments and assumes a central facility with a raster scanner and a minicomputer to serve many users. The systems designers, by adopting a highly interactive approach to the control of the data processing, have provided for persons with little or no computer experience to use the system and have minimized the need for a user manual. This report on SCANIT is designed to aid the maintenance programmer locate needed information easily and to assure an adequate level of documentation for each routine.
