This site uses various maps of Hawaii to illustrate the possibilities of Web GIS 

The following maps tell a story about Hawaii through map applications which allows  viewing and, with some applications, interaction with the maps. There are a total of 10  different maps, each utilizing JavaScripting to best present a variety of information.  There are three basic mapping services available: tiled maps in the form of images such as  jpgs and pngs (fast loading and pre-made; limits to interaction with the Internet user),  dynamic images (drawn on the fly and allow the user to participate to varying degrees  with the display of the map), and feature services (which have servers that will download  xml or JSON (JavaScript code files), rather than images).  Querying is possible through Internet web services; a simple example is Google Maps.
