Abstract: A system and a method are described for extracting a target area of an aviation document. The system and method include inputting the aviation document to an image segmentation model. The aviation document includes a target area of interest that is shown to scale. The image segmentation model generates a first output that provides a predicted location of the target AOI relative to the aviation document. The aviation document is input to an edge/contour detection algorithm that generates a second output which identifies a plurality of candidate polygons based on content in the aviation document. The first output is analyzed with the second output to determine a selected polygon of the candidate polygons in the second output that corresponds with the predicted location of the target AOI in the first output. Pixel coordinate values of the selected polygon in the aviation document are determined.

Abstract: A system and a method include identifying characteristics of a map of a geographic location, and placing plural first lines of longitude and plural first lines of latitude of the map based in part on the characteristics. The first lines of longitude and latitude intersect with each other to create plural theoretical intersections. A magnification of a segment of the map, that includes the first theoretical intersection, is changed. One or more edges associated with one or more second lines of longitude or latitude are identified, and a location of a first actual intersection within the first segment is determined based in part on the identification of the one or more edges associated with the second lines of longitude and latitude.
