• It must run as a turnkey application. Double-clicking on the launcher script must
start the PyQt program, load all the data, and present a complete working applica-
tion to the user.
• The user interface must be as professional as possible, with keyboard shortcuts
and good-looking toolbar icons.
• When the user clicks on a landmark, the name and jurisdiction, time zone, and lat-
itude/longitude for that landmark should be displayed.
• The look and feel should be as similar as possible to Google Maps.
Note
This last requirement is an important point, as the zooming and panning tools
built into QGIS are more complicated than what we would like to have in a turn-
key mapping application. Most users are already familiar with the behavior of
Google Maps, and we want to mimic this behavior rather than using the default
panning and zooming tools supplied by QGIS.
Without further delay, let's start building our application. Our first step will be to down-
load the geospatial data the application will be based on.
