for each of the one or more images:
identifying, based on one or more features in the image, one or more positions in the image from where scan line data is to be extracted from the image;
extracting scan line data from the image, the extracting including acquiring, as the scan line data, from each of the one or more positions in the image, a portion of image data from the image having a specified shape; and
storing the scan line data in a memory along with positional data identifying a location where the image was captured.
