Mr Minton writes " 
During the month of May 2008, I digitized approximately 8,000 island polygons scattered throughout the southern Pacific Ocean. All of Papua New Guinea to the Cook Islands were mapped at EVS precision using Landsat ETM+ base imagery. And I got paid for my efforts! I wanted to enhance my mapping by including reef features. Here is how I added those features."

Sea Breeze for NASA World Wind
[+]
blueheeler writes "PanglossTech has released Sea Breeze for NASA World Wind. This World Wind add-on is a large and sweeping collection of high resolution maps depicting a wide array of oceanic characteristics and properties. Data categories include Bathymetry, Seafloor Features, Geology, Geophysics, Oceanography and Meteorology.
This package includes over 600 maps covering about 50 physical, chemical and biological parameters of the world's oceans and seas. The highest resolution publicly available data is compiled from the leading, most up to date sources to provide presentation quality maps of many important marine variables.
Sea Breeze for World Wind allows you to readily visualize the complex processes that underlie the behavior of Earth's largest climatic and biological engine. It is designed to provide a scientific reference source of oceanographic data, as well as an intuitive interface for the educational exploration of oceanic properties."

8,000 Pacific Islands Mapped at EVS Precision
[+]
Mr Minton writes "The 8,000 islands located in the following island groups: Papua New Guinea, Solomon Islands, Vanuatu, Fiji, Cook Islands, Western Samoa, Tonga and portions of Kiribati were mapped at EVS precision. Using Landsat ETM+ ortorectified image mosaics, which typically resolve to 14.5 meters per pixel as base imagery, Mr Minton spent in excess of 240-hours over 31-days digitizing, correcting and finalizing island shorelines throughout this region of the Pacific. Mr Minton used a variety of strategies to resolve cloud-obscured shorelines. Those that ultimately could not be resolved were mapped using World Vector shorelines. This impressive effort is being fine tuned using 1990 Landsat imagery, when available."
Comparison - Big Three Maps and EVS Precision Maps 6 comments

Mr Minton writes "Whose shoreline maps are currently the most accurate? Is it Google Maps? They have loads of bucks and a keen desire to put the best product into their sites. They must have the most accurate shorelines. Right? Nope, not them. Yahoo! Maps, the current darling of the stock market and Google "wannabe", has the same clunky shoreline used by Google. MS Live Search Maps has the prettiest maps. Lots of shaded hills and valleys, but clunky shorelines. For sure, MicroSoft must have the most accurate shorelines. For sure, not.
Would you believe, EVS Precision Maps has the most accurate shorelines..."
