Thread:Semantic-mediawiki.org:Community portal/Query on specific value of Geographical coordinate type property returns nothing/reply (5)

First of all, it seems to look up the latitude in the field "o_serialized" and the longitude in the "o_lat" field.

Interesting. I tried repdoucing this but ran into another issue... Anyway, I created to keep track of the issue.

the values themselves are off, probably because of some precision problem when converting to and from float format and DMS.

Not a lot SMW can do about this. More the respnsibility of the Maps and Semantic Maps extensions. SMW 1.9 will be using Maps 3.0.x, which has a rewritten coordinate parser, in which some bugs are fixed compared to the one in Maps 2.0.x. Perhaps that will fix your problem.

If you just want to select on one exact value and always enter it in the exact same format (inc same spaces and stuff), you could ofc just store it using an extra string property. To ensure the format is the same you could use the #coordinates function in the way I recommended against. A rather big hack, but might work fine for you.

How all of this relates to the crash occuring when dropping the "|?Name" part, I don't know yet.

Both these issues do not relate to the one for which you provided a stack trace.
