In-Depth Information
be represented within a single virtual environment, ranging from building blocks to
life-size
build-
ings. The importation of GIS data within virtual worlds has a huge potential for the display, query-
ing and discussion of data either directly from native GIS formats (e.g. shapefiles) or by creating
map boards. For example, Figure 4.6b illustrates a map display for global literacy rates. This ability
opens a range of possibilities for importing geographical data into an environment that is ripe for
public participation and collaboration-type outreach activities (Hudson-Smith, 2003).
While the visualisation and querying of geographical information is one avenue of research, the
acquisition of real-time data is also of interest. For example, Figure 4.6c depicts how one can import
RSS feeds and run them through a text board or how it is possible to link near real-time feeds to
geographic places. For example, in Figure 4.6d, we show real-world weather data in Second Life -
global maps displaying temperature, rainfall, wind speed, barometric pressure and humidity from
around the world.
