Geographic information systems using digital watermarks
First Claim
Patent Images
1. A geographic information system (GIS) comprising a computer including a display, electronic processing circuitry and memory in communication with the electronic processing circuitry, wherein the memory includes an information layer associated with an image, an improvement comprising:
- a digital watermark embedded in the image, the digital watermark including an identifier;
digital watermark decoding instructions stored in said memory for execution on said electronic processing circuitry; and
software instructions stored in said memory for execution on said electronic processing circuitry, said software instructions comprising instructions to;
initiate decoding of the digital watermark from the image to obtain the identifier;
locate the information layer based on at least the obtained identifier; and
display the information layer relative to the image via said display.
