1.2.6. Unit-Summary

To be able to pack the entire content of a paper map in a screen map, we have to implement some interactive tools, otherwise the map's details could not be detected. The most important tools are:

  • Map layer control
  • Navigation

Sometimes it is reasonable to implement adaptive zooming which describes the adjustment of a map, its contents and the symbolization to target scale in consequence of a zooming operation.

An application with implemented adaptive zooming is the webservice of Swissgeo. We exctracted the different zooming level that you can choose in Swissgeo and produced a quicktime movie (click on the thumbnail):

You are free to enter your own address on the Swissgeo Webpage and explore the whole application.

Interactive tools that are often implemented in screen maps are:

  • Mouse over effects
  • Click effects
  • Interactive Legends
