Hi,
The default distance units measurement is "miles". I've just committed a
major change of the codes, including the following updates:
1) Support spatial indexing of WKT literal, including Point, Polygon or any
other kinds of shapes.
2) New property functions of "withinCirle", "withinBox", "intersectsBox",
"north", "south", "east", "west"
3) Support different distance units for "nearby", such as "miles",
"kilometers", "degrees", "meters" and so on.
4) Examples are updated [1]. You can play with the new features of
jena-spatial.
It's almost half-way of the GSoC project. In the upcoming second half, I'll
bring more visibility of code progress to the community, at least
one report per week. Thanks to Andy for pointing it out!

In the example query there is:
?s spatial:nearby (51.3000 -2.71000 100)
What units are the "100"?
Can the application provide different units?

Things are looking very good.
How does this fit with the original plan in terms of functionality
available?
As we enter the second part of the GSoC, we need to be thinking about
* A release
That does not mean it's complete and a release needn't be a major cost
in time. Having even one or two people try it out really helps in
understanding what people might do with spatial indexing.
It can be a message to the users Jena mailing list announcing status of
the project and assuming interested people will grab the source and
compile a jar for themselves.
But, if you want to, we can do something more packaged - anything up to
and including migrating the code to Jena SVN and putting in a Jenkins
job to build it into Jena's snapshot maven repository that's doable.
A couple of things go with that:
* Testing
src/java/test is a bit empty :-)
* User documentation
Enough that someone can setup and use the project - short, to the point
and "now" is better than long and detailed and "later". (The final
phase of GSoC is write-up - that's needs to cover the next developers to
come along.)
What do you think about this?
Andy
