Webmapping: free GIS interfaces on the internet
There are thousands of GIS interfaces available free on the internet. These interfaces often referred to as interactive maps or webmapping are a great way to start using GIS in the classroom without buying any GIS software. The site below lists a wide range of webmapping sites using ESRI based GIS software. They give an excellent idea of the application of GIS in government and industry whilst providing some potential learning activities for the geography classroom.
Other webmapping sites are:
National Soil Resource Institute
This website is a great resource to use when studying soils. The interactive map of UK soils and associated topographic maps provide plenty of practical examples of the relationship between soils and location.
From the USGS and Smithsonian
This dynamic planet resource provides an interactive map of the earth showing plate boundaries with a GIS interface (called the interactive map) to add and change the layers displayed. This is a great resource for natural hazards topics. Also have a look at the interactive map for the Arctic and Antarctic via the home page.

This sites provides a desktop Internet GIS for Apple and PC. A free user friendly Internet GIS is available to be downloaded from teh site at http://udig.refractions.net/
US Census Bureau
The US Census is also a great source of webmapping facilities and resources. If you are interested in doing any geography related to the US, then this site is incredibly rich in data. Go to the following links to access free data and mapping applications
