What is GIS?

A geographic information system (GIS) is a system for capturing, storing, analyzing and managing data and associated attributes which are spatially referenced to the earth. In the strictest sense, it is a computer system capable of integrating, storing, editing, analyzing, sharing, and displaying geographically-referenced information. In a more generic sense, GIS is a tool that allows users to create interactive queries (user created searches), analyze the spatial information, edit data, maps, and present the results of all these operations. Geographic information science is the science underlying the geographic concepts, applications and systems, taught in degree and GIS Certificate programs at many universities.
Geographic information system technology can be used for scientific investigations, resource management, asset management, Environmental Impact Assessment, Urban planning, cartography, criminology, history, sales, marketing, and logistics. For example, GIS might allow emergency planners to easily calculate emergency response times in the event of a natural disaster, GIS might be used to find wetlands that need protection from pollution, or GIS can be used by a company to site a new business to take advantage of a previously underserved market.

What is GPS?

The Global Positioning System (GPS) is currently the only fully functional Global Navigation Satellite System (GNSS). Utilizing a constellation of at least 24 medium Earth orbit satellites that transmit precise microwave signals, the system enables a GPS receiver to determine its location, speed and direction. GPS has become a widely used aid to navigation worldwide, and a useful tool for map-making, land surveying, commerce, and scientific uses. GPS also provides a precise time reference used in many applications including scientific study of earthquakes, and synchronization of telecommunications networks. (Source: Wikipedia)

Put this GIS and GPS together - it becomes Geocaching.
Geocaching is an outdoor treasure-hunting game in which the participants use a Global Positioning System (GPS) receiver or other navigational techniques to hide and seek containers (called "geocaches" or "caches") anywhere in the world. A typical cache is a small waterproof container containing a logbook and "treasure," usually toys or trinkets of little value. Today, well over 440,000 geocaches are registered on various websites devoted to the sport. Geocaches are currently placed in 222 countries around the world and on all seven continents, including Antarctica. (Source: Wikipedia)

Platial Maps

Platial maps, The People's Guide to Who and What's Nearby, a free resource where hundreds of thousands of people around the world share and discover all kinds of Places. Anyone can map just about anything including their towns, lives, travels, feeds, files, photos, video and stories in one simple interface. Lots of fun to use - it is like Google Maps but with a social networking addition.

Using Google Earth

the basics - http://www.gearthblog.com/basics.html
Google Earth is an interactive mapping application that allows users to navigate (or "fly") the entire globe, viewing satellite imagery with overlays of roads, buildings, geographic features, and the like. Educators can use it to assess and bolster students' visual literacy. Students can use it to develop a context for spatial and cultural differences globally.
