According to CNET , Google has begun work on creating “Google Ocean” (though the name will likely change). Expectedly, the data layers will include content such as currents, reefs, shipwrecks and algae blooms, etc.
While this tool will be useful for oceanographers to geologist to treasure hunters, hopefully it will inspire more students to become marine [...]

It’s probably a frustrating experience for most people when they attempt to export their GPS tracks into Google Earth.

There are probably other ways to do this without using paying for Google Earth Plus or using professional GIS software, but I haven’t found any obvious solutions. I think a person’s best bet is to investigate GPSBabel [...]

As both satellite and cellular navigation systems become more popular, there is massive potential for these systems to change driving habits; especially in context of networked navigation devices.
When traffic and stop lights are taken into account, the shortest route may not be the most efficient; network connectivity among navigation devices will allow drivers to use [...]

Last week, the BBC reported the first of 30 satellites of the Galileo satellite navigation system was launched from Kazakhstan. While remnants of GLONASS exist,  the United States’ NAVSTAR Global Positioning System is the only fully operational Global Navigation Satellite System. Galileo is designed to be technologically complementary to NAVSTAR and will enhance location-based technology.
Using [...]

Although there are several commercial software programs for converting shapefiles into .kmz or .kml formats, here is free program created by a student at the University of Arizona.
The program is designed for use in Google Earth 3, there will be minor symbology problems if the outputs are used in Google Earth 4 (large pushpins will [...]

I realize this message is only useful to a handful of people, but it can seem quite daunting and bewildering when first using Classification and Regression Trees ( CART) algorithms for classifying imagery,
I’ve been utilizing CART as a method of supervised classification for a few years. Not only is it the primary tool for the [...]

While we’ll be fortunate if these ships are never again mobilized; I hope we use these ships for artificial [...]
