Google has puts Costa Rica on the map. Literally.
Google acquired Keyhole Corp. last October 2004 adding the firmís service to its growing list of its satellite imaging offerings.
Founded in 2001, Keyhole is the 3D digital Earth pioneer of the only company to deliver a 3D digital model of the entire Earth via the Internet.
Costa Rica is now included in medium resolution. At this 80-meter to 200-meter view one cannot see what Ticos are having for breakfast, but one can see the craters of most of the country's volcanoes in great detail along with other sights of the nation.
Presently, a number of Earth observation systems continuously monitor the surface. The U.S. National Aeronautics and Space Administration along with the U.S. Geological Survey and other organization have donated maps to countries of Central America, allowing them to develop strategies for protecting the environment and for urban planning. However, the availability of the maps has been limited to people in academics and government.
Costa Rica is now available to the public, and it is the only country in Central America that is, thanks to Google. Virtual tourists can actually tour almost the entire country using Keyhole. Real estate developers can do site analysis and prepare movies for prospective clients along with high-resolution printouts. The uses of digital cartography are endless.
This technology is just getting better by the year. New satellites can photograph the earth at an incredible one-foot spatial resolution.
What is spatial resolution?
Spatial resolution is the distance along the ground between samples in a satellite photograph. If a satellite image has a spatial resolution of 30 meters, this means that one pixel in the image represents a square of 30 by 30 meters on the Earths surface. In an image of this resolution, one cannot see small buildings, but can definitely see a football field or plantations. At one-foot resolution, one can see someone in a swimming pool.
Satellites are contributing to the growing field of GIS.
What is GIS?
Maps have always been a powerful way to represent information. Geographic information systems (GIS) combines the power of maps, satellite images, and aerial photographs with databases. They store information behind the maps and images to study natural hazards and disasters, population growth, water resources, and minerals deposits, to name only a few topics on a very long list.
