Satellite Maps: Satellite maps are useful tools since they give the user a panoramic view of their city, homes and other areas of interest. Most satellite map providers have links to points of interest like the Hoover Dam, Colorado, or the Statue of Liberty, Manhattan. The features and details of these landmarks are easily discernible on these maps.
Google satellite maps: Google Earth blends satellite imagery, maps and the powerful features of Google Search to put the world's geographic information on your desktop. Google has added high-resolution satellite images to its maps and local search services, offering a 3D view of millions of locations throughout the U.S., Canada, and the world.
Google Maps even have a overlay feature where guided street maps can be laid directly on top of the satellite map, giving users a clear idea of what they’re looking at and how the area is located relative to nearby towns and roads. This feature can be instrumental when searching for an area without prominent geographical features like lakes and rivers. Google Earth is another great step towards the growth of the Google search engine.
Satellite Map images: Satellite imagery gives climatic information such as cloud patterns, system formations like El Nino, as observed from geo-stationary and polar orbiting satellites. El Nino is a climatic disturbance of the ocean system in the tropical Pacific region, which has important effects on weather and climates around the world. Satellite imagery is a useful tool for locating and following storm systems anywhere around the globe.
The observation of 24-hr live climatic changes is conducted by monitoring developing cloud patterns, by using infrared imagery. Infrared satellite imagery uses heat mechanism for detecting climatic changes globally. This technology detects the presence of clouds by their temperature. The coldest clouds are displayed in bright white color, while the warmest appear dark gray. In general, the coldest clouds are found at high altitudes while warmer clouds are found closer to the earth's surface. On the enhanced satellite imagery, the coldest clouds are color coded in shades of yellow, red and purple. Thus, the areas receiving the highest precipitation can be found.
Free Satellite Maps: Satellite images and photos are available for all major cities in the U.S. and Canada, and for many smaller towns as well. Another service called Terraserver has gathered satellite maps from many different sources under one consolidated website. You can view all satellite maps at a degree of 8-meter resolution and above, which are available for free. Subscribers to the site may go up to the maximum resolution available for each image source, which typically ranges between 6 inches and 2 meters in areas with high-resolution imagery.
Yahoo Satellite Maps: Yahoo Local Maps is presently undergoing beta testing, and has been created for users who want to generate a local map, or want to find out directions. The maps generated here are far more interactive and are geared towards helping users to search for areas where certain local events have taken place or to locate businesses. The maps are interactive as Flash is used for the animation , so the user may need to upgrade to the latest free version of Macromedia Flash Player.There's also a non-Flash, non-beta version of Local Maps available on Yahoo, but it lacks a lot of the stylish effects which is present in the Flash-y beta version.
