[OSM-dev] XAPI and other solutions

[Martijn van Exel]

Hi Pierre,

As far as XAPI servers go I have given up for now, although MapQuest is
running a more reliable instance[1] that may be useful, although they employ
Ian's Java implementation as well so the same bbox limitations likely apply.

I am, in fact, working on a similar project in the Netherlands and for an
up-to-date data feed for CCTV cameras I use the process described here[2].
I'd love to compare that to your approach, we can probably benefit from each
other's work.

Best
Martijn
