**GPS - Ding Chen**

 * What is GPS?**
 * GPS- Global Positioning System.**
 * It's a satellite-based navigation system made up of a network of 24 satellites placed into orbit. Before GPS was originally intended for military applications. Now every public can use GPS. The good place is working in any weather condition. People through the GPS easy to find definite person's geographical position. In the real life more people use it in the mapping online journey. When people want to drive car to one place, but don't know which road is right, they can think to use GPS.**


 * Using place:**
 * -Military**
 * -Business**
 * -Geography**

Online mapping is the process of creating and publishing a map online that allows a user to interact with the map content. Online mapping is not simply posting a static map in an image format (e.g., JPG, PDF) to a web site. Online mapping provides dynamic maps that change based on a user's requests, such as zooming in and out, panning or moving the map, and identifying features on the map. The information reported back to the user is usually extracted directly from a database. For example, a user may want to know more about a building feature on the map. When the user clicks on that building, information such as the name of the building, the year it was built, and the building's use might be the information attributes that are returned.

How does it work?
Typically, online mapping site users start by viewing a map on a web site. As the user moves around the map, the web browser sends a request to a server that generates a revised map image and sends that image to a web server and then, back to the web browser. These servers are typically called Internet Map Servers (IMS). Companies and agencies (Google, ESRI, Microsoft, NASA, USGS) run mapping servers that are publicly accessible. Universities and individual researchers also own map servers to distribute imagery and data. Your online mapping web site can easily incorporate the image and data feeds from others' IMS sites. In either case, you can create online mapping sites that consume maps and data from one or more of these Internet Map Servers. [|Getting Started]

[|Online Mapping Sites of Various Levels]

First well-known online mapping service: MapQuest, 1996

Google - Google Maps, Google Earth Yahoo

Functions: zooming and reentering topographical maps satellite images weather & climate maps demographic maps traffic information

Most sophisticated sites - GPS Wireless equipped mobile user with moment-to-moment position data Street by street directions [|WhatIs]

Types:

Analytic GIS analysis, with geodata provided or with geodata uploaded by the user -often carried out by a serverside GIS & client displays result of analysis

Animated Shows changes in the map over time by animating one of the graphical or temporal variables. Uses: SVG, Adobe Flash, Java, Quicktime E.g. weather maps, maps displaying natural phenomena: water currents, wind patterns, traffic, flow, trade flow, communication patterns, social studies projects, and for college life, etc.

Collaborative Equivalent of Wikipedia. E.g. Google Map Maker, OpenStreetMap, WikiMapia

Customisable web maps Offer APIs for reuse in other people's web pages and products. E.g. Open Layers Framework, Yahoo! Maps and Google Maps

It's a computer system that integrate hardware, software, data capturing, managing and display with geographically referenced information. It's using 40 years to developed. More and more places to use GIS. Like in GPS and path optimize have more and more vital role.=====

Geographic information system (GIS) technology can be used for scientific investigations, resource management, and development planning.
