Abstract
A system and associated method for extracting image data from a representation of a geographic area to generate a digital geographic database that can be accessed by computer programs to analyze various features contained within the database. In particular, the method includes scanning an image of a geographic area, manipulating the image into a processable format of a plurality of pixels, and submitting the format to a neural network with user-guided rules. The neural network classifies the format into a plurality of categories which comprise the geographic database, thus foregoing the need to manually identify and classify each pixel of the scanned image as having a particular feature. To enhance the processing and structure of the database, an optimizer and a combiner are employed. Accordingly, the method provides a digital geographic database for use by government agencies, urban planners and any user desiring to obtain information from a geographic representation.
