Static maps may be existing maps that have been scanned for display on the Web. The
site for the David Rumsey map collection,
www.davidrumsey.com, is an example
of this type of Web mapping (Figure 11.4). The maps are historic maps and the only
“interaction” possible is panning and zooming. The maps are not “clickable,” that is,
one cannot click the mouse on a map and get a link to more information. Metadata
for the maps is available through the database. The colors of the maps are their origi-
nal colors, which may or may not translate well to Web viewing.
Other static maps are designed specifically for Web viewing that have panning
and zooming as the only interactive options. The design concerns for these maps
include the usual elements of title, legend, scale, and the like of traditional maps, plus
the locations of pan and zoom bars and choice of color and background.
Interactive static maps are “clickable”; rolling the mouse over an area and/or
clicking the mouse button provides additional information by bringing up a differ-
ent layer of information. For example, rolling the mouse over buildings shown on a
campus map or city map might show the name of the building or a voice might speak
the name. Clicking on different areas of a choropleth map might give the data value
for the enumeration area.
Dynamic Web maps also include animation and multimedia and are gener-
ally interactive. Dynamic maps are all computer-created, but some are specifically
designed for the Web, whereas others may have been designed originally to be dis-
seminated on CD or DVD.
