Dave,

You could add a wiki page with this. But please give a help there, it took me a while I had to use the textual smaller/larger links to have the bounding box change.

You could also make a report/quick report on places that opens this page in your browser. That would give you the option to create a plugin for gramps that makes your applet more visible and allows you to share the work with new users.

Hm, I realize I left out a couple of points I meant to make...

  - Place databases like geonames.org go down to the level of cities or
towns.  Geocoding (computing coordinates based on address) is
notoriously inaccurate and often fails, especially on historical
addresses.  GRAMPS users will often have information more precise than
city, but less precise than an actual building location.  Perhaps just a
street name, or a particular block, or a distance from landmark, etc.  A
tool like this is useful for determining approximate coordinates that
are better than just the city coords using that information.

  - Besides adjusting zoom level based on precision of coordinates,
GeoView could also display the area of uncertainty, similar to the
bounding box I draw (though a circle, if possible, would be more
visually pleasing).  That raises awareness that, like most Places, the
coordinates don't reference just a single, specific point, but rather a
general area of interest around that point, the size of which can vary
depending on the Place being referenced.
