EVS-Islands: How To Find Hidden Reefs Using Pulau Bankobankoang ID

The above map shows some of my completed island mapping projects. Each icon contains the name of the primary island associated with the project and a link to the post. Once all of my projects are posted, the map will be covered with icons. To productively use the map, zoom into a region of interest. Then select an icon.

Each of my maps is constructed of numerous layers of information. All of the layers are vector files. I will make these files available upon request. You are free to use them with certain restrictions - 1) Don't sell them. You can use them on research projects, post them to your website or things of that nature. If you aren't sure about the use of my maps, drop me a line and we can discuss your idea. 2) Give me credit when you use my vectors or images of my maps. Credit them to Peter Minton @ EVS-Islands

If I have the island vector file(s) and based upon your need, I will make them available. Images of my maps are yours to download and use, with the above restrictions applicable. Enjoy!

I will post Sailing Directions information and any Internet information on this island later. I just wanted to get the project posted. The real breakthrough on this image and map is the ability to more accurately digitize and map the EVS Reef Deep layer.

The solid yellow in the above image is the hidden reef layer, which I have labeled as EVS Reef Deep. There is an even more subtle area that is defined by scattered yellow dots. This is most likely an even deeper reef layer.

Enjoy!

Your final map looks pretty nice. At first I thought you performed some kind of pixel classification on the landsat image. But that color dodge effect sounds more like a filter from photoshop or something. Could you please explain how u obtained this effect?
