yes, a lot of the geosparql functions will push you towards geo.
It might be better to just reuse the existing low level functions. My first
spatial implementation for Jena in 2006 made use of the JTS Topology Suite.
JTS is still used in Jena today to run some of the low level evaluation
that idea, needs a bit more clarification

In terms of geo you would talk about some sort of equidistant projection
that is available via the CRS/SRS.This is currently implemented with Apache
SIS in Jena.
But it sounds like geo isn't really your thing here, so in conclusion
geosparql isn't either as it's all about geo data.
What type of
Marco,
Is your earlier code available in a repository somewhere? I'd love to get
a head start on the functions.

It used to be all on Google Code. I believe Google folded that site
a few years ago. I will have a look through my backups. But to be frank it
would be straightforward to implement nowadays and the old code would be
pre Jena 3.
You might be able to get at some of the pre 2007 stuff by way of

Perhaps we should think about a Geometry SPARQL extension.
