Nice wording, Steve.<br>

This is why YAAC keeps the OpenStreetMap data in vector format
and renders it "on-the-fly" for the desired viewport (window
size, map center, and zoom level). It may be computationally
costly, but it is accurate.<br>

The problem with OSM is that it tethers you to the Internet.
Basically useless for mobile operation or operations like Bob's
proposed cave event. That's why I won't consider any APRS app that
can't use locally-stored vector data such as Precision Mapping,
MapPoint, Garmin Mapsource, etc. <br>
<br>
For those that keep glibly saying you can always use wireless data
access to the Internet and that assume they are going to replace
their dedicated car GPS with a smartphone:<br>
<br>
1) As cellular data quotas keep continually getting reduced (and
rates increased), continuously accessing Google Maps or OSM is going
to get astronomically expensive as you blow through your cell plan's
data quota in the first week of each month.<br>
<br>
2) For those that live their lives in built-up urban areas and
take ubiquitous cellular coverage for granted:..... There are
HUNDREDS OF THOUSANDS of square miles of North America with NO
WIRELESS COVERAGE of any kind. Especially in the west (or in
mountainous terrain), the moment you turn off major highways, you
step into a black hole in cellular terms. <br>
