The problem with flickr is not searching by multiple tags, this is
well supported by the API.  The problem is searching by partial tags

e.g. I want to find everything tagged with geo:long=-1.5 ->
geo:long-1.0, I have to search on every value in between.

There are (at least) two solutions to this.
- the geobloggers solution i.e. crawl flickr and build your own
database that does support partial matching
- the photomap solution i.e. add a lot more tags: e.g.
http://flickr.com/photos/63699853@N00/92211964/

Even if you chose not to use photomap I'd encourage you to consider adding:

-  some sort of tag to help build a hierarchy of places.  E.g. dirt
roads v.s. intersections v.s. landmarks etc.   This will probably be
much easier to do as you walk the island rather than later.  My
approach with PhotoMap was to use a number (pmType:01 etc.) as using
descriptive words didn't translate well across different types of
locations (urban/rural/tropical island).  Also I tagged to make the
search easier e.g. type 3 is tagged 1 and 2 and 3

- point of view i.e. which way the camera was facing

The PhotoMap source is open, and available from the home page.  If you
have questions let me know.

- PhotoMap is still in its early days, and I'm always looking for
feedback.  Also I,m not opposed to making some changes...

I have some scripts to get at geotagged photos, with tripletags or exif. Maybe we can ask Dan Catt for a download of the geobloggers archive for IoW.
