Abstract
System and method for displaying an encoded standard-formatted image with information including, but not limited to, geospatial information. This information, possibly in mark-up language format, can be quickly accessed and used to modify the image to which it is appended, or it can be ignored because the image itself remains unchanged.
Claims18
An automatic method for displaying a standard formatted image in a geospatial information system as a map image comprising:
- automatically searching for a pre-selected tag at the end of an augmented standard-formatted image, the augmented standard-formatted image including the standard-formatted image, mark-up language information, a mark-up language information size, and a tag at the end of the augmented standard-formatted image;
- if the tag is found, automatically decoding the mark-up language information, the mark-up language information being found at a pre-selected position relative to the tag;
- and
- automatically displaying the standard-formatted image as the map image based on the decoded mark-up language information.
A computer system for displaying a standard formatted image in a geospatial information system as a map image comprising:
- an information receiver automatically receiving standard-formatted image information associated with the standard-formatted image;
- a formatter automatically formatting the standard-formatted image information into mark-up language information;
- a sizer automatically computing a mark-up language information size of the mark-up language information;
- an image modifier automatically creating an augmented standard-formatted image by concatenating the standard-formatted information, the mark-up language information size, and a tag onto the standard-formatted image, the tag being concatenated at the end of the augmented standard-formatted image;
- and
- an image display automatically displaying the augmented standard-formatted image if the augmented standard-formatted image includes the tag,
- wherein the mark-up language information includes a digital signature.
A computer method for displaying a standard formatted image in a geospatial information system as a map image comprising:
- computer code stored on computer-readable media executing automatically searching for a pre-selected tag at the end of an augmented standard-formatted image, the augmented standard-formatted image including the standard-formatted image, mark-up language information, a mark-up language information size of the mark-up language information, and the pre-selected tag at the end of the augmented standard-formatted image;
- if the pre-selected tag is found, automatically decoding the mark-up language information, the mark-up language information being found at a pre-selected position relative to the pre-selected tag;
- and
- automatically displaying the standard-formatted image as the map image based on the decoded mark-up language information.
