Some tima ago (a year, probably) I posted a message about modifying ht://Dig to do a geographic search. At the time there was some interest expressed.
The original modifications were against an earlier tarball - 3.1.5 I think. I intended to rework the modifications against the CVS version, and it has taken rather a long time. I finally did it in October/November last year. I updated the patch last month and everything still compiles and runs. Essentially there are 3 bits of code that were added: - code in htsearch to parse geotags from HTML - META statements with position information. This could be extended to parse similar metadata in HTML or XML - code in htdig to store position data for documents, to compute a "search distance", search ordered by distance, graphical input and output of search location - code in htsearch to restrict searches to certain geographic regions, or pages with geotags, in order to search for geographically-enabled pages in a much larger body of regular pages The modifications are done with configuration elements such that the normal text-based search of ht://Dig is unaffected The modifications are described and patch file available from http://andrew.triumf.ca/htdig/mods/ A demonstration set of data (pages for international airports with latitude/longitude information) is included There are also a couple of modifications associated with trying to index non-text media (splitting max_doc_size between text and e.g. movies), and a couple of other minor changes (adding an HTTP/1.1 range request to retrieve partial documents, instead of asking for the whole thing then dropping the connection) The site geotags.com is still using the old version. There is some problem with indexing a larger set of pages that seems to be fixed in the 3.2 release. An upgrade is planned ...
