WiscMap is an online mapping application that draws
upon geospatial data from distributed online sources and integrates
them into a single view.
Interactivity was also the guiding principle behind our WiscMap design. Conventional web maps can be
cumbersome to use, because a new map image must be generated every time a user pans the map or changes
the map layers that are being displayed. In order to support continuous panning and real-time layer
management, we designed a system for caching and reusing map images. The first time a set of map tiles
are requested at a particular scale and extent, they are generated on-the-fly by MapServer. The tiles
are then stored for later use, so subsequent requests are handled almost instantaneously. WiscMap
incorporates other design features to improve interactivity, including on-the-fly layer handling, a drag-box
zooming tool and navigation history.
WiscMap is a work in progess. WiscMap has been developed
to work optimally on a 1024 x 768 screen resolution with IE6+, NS6+,
& Mozilla 1+ browsers on PC and Mac platforms. There are known issues
with Safari on the Mac platform. Visit
