How do we put the underwater puzzle together to make an image map?
1) Collect the Puzzle Pieces
The image on the left is one of the puzzle pieces of our underwater image map of Monterey Bay. It is a sonar strip collected by a fish towed by a ship. You can move the scroll bar up and down to see how long it is!
This sonar strip was shrunk down to fit better on your computer screen - originally the image was 10 times longer and wider! If we printed it out before we shrunk it, it would have been over 8 feet long!!! The strip shows an area of the land underwater about five miles long.
2) Put the Puzzle Together!
The images below show where the strip fits in the big puzzle we put together. This is no ordinary puzzle, though. To make the strip be in the correct location, we had to stretch it, twist it, and push it into place with computer software. This would be sort of like making a jigsaw puzzle piece fit into the right place by cutting it with scissors and pounding it with a hammer until it fit -- just not as noisy!
3) Where Does Our Sonar Strip Belong in the Puzzle?
This image has numbers and arrows matching the numbers on the left side of the strip to show you where different points ended up when we were done with our sonar puzzle, which is called a mosaic. Scroll the strip up and down to find the numbers and match them to the numbers below.
