Gaining overview with transient focus+context maps

Abstract: Gaining an overview of large spatial data sets presents a challenge common to various domains. 'Overviewing' spatial data involves viewing different areas of focus and context at different scales and requires access to detail from zoomed-out views. Standard pan and zoom interfaces provide limited support with this. Motivated by the application scenario of flood risk monitoring, we extend pan and zoom affordances with a combination of focus+context techniques and multiple maps to support 'overviewing' spatial d… Show more

“…Other types of focus map techniques were also proposed, including those where the rim of the lens delimiting the magnified area is not visible [92,93,94]. Transient overlays are another mixed technique offering a quick preview of a focus area, which can be later decoupled from panning and zooming for separate viewing by the user [95]. Other proposed multi-focus techniques, such as Mélange, connect two focus views with a middle perspective [96].…”
