highways; Interstate highway exits and exit services information;
large- and medium-sized lakes and streams and more than 60,000
navigation aids and 10,000 wrecks and obstructions in U.S. coastal and
Great Lakes waters.
MapCreate custom maps include massive amounts of information not
found in the background map. MapCreate contains the searchable
Points of Interest database, all the minor roads and streets, all the
landmark features (such as summits, schools, radio towers, etc.); more
rivers, streams, smaller lakes and ponds and their names.
What's more important is the large-scale map detail that allows your
GPS unit to show a higher level of position accuracy. For example, the
background map would show you the general outline and approximate
shape of a coastline or water body, but the higher detail in MapCreate
shows the shoreline completely and accurately (finer detail). Many
smaller islands would not be included in the background map, but are
in MapCreate.
When the map is zoomed out far enough, most POIs appear as square
dots (left). As you zoom in closer, the symbols become readable icons.
In the 0.3-mile zoom example (right), the cursor has selected Cholita's
Mexican Restaurant POI, which triggers a pop-up box with the POI
name. This pop-up box works on POIs at any zoom range.
Tip:
In some urban areas, businesses are so close to one another their
POI icons crowd each other on the screen. In the preceding figure,
you can see a packed string of POIs all along the west half of 11th
Street. You can reduce screen clutter and make streets and other
map features easier to see by turning off POIs you're not watching
for. To see how, check the text on Map Detail Category Selection, in
