Those either aren't exhaustive (postgis) or don't have pictures (wiki). I would
like to be able to look up "FF2F1F212" and see a picture of it.
I think a difference is that I am not interested in using a matrix to implement
a function like st_within(), but rather I am querying a database looking for
relationships and how to deal with them. In my case, also, the query will never
return a string with wildcards in it, because it will give me the exact
relationship. (Maybe the above links are exhaustive if you count wildcards,
though...)
Sorry -- I tried to make clear that I had already read the docs that are easily
available. Thanks for the explicit links though.
