Nuovi Metodi di visualizzazione geografica: l'approccio Focus+Glue+Context

Abstract


New cartographic visualization methods:

the Focus+Glue+Context approach


Focus+Glue+Context is a new cartographic visualization method specifically designed to solve the fruition problems connected with the use of mobile devices and web mapping services. The objective of the F+G+C approach is to reduce users cognitive efforts when reading a map: to do so, the area of interest is ‘highlighted’ in a lower and more detailed scale through a fisheye lens effect, while the sorrouding context, useful to the user to determine the items relationships in a map, is maintained on a higher scale.
