Description

This is largely so that UK grid coordinate based guides work - they are currently based on the Airy system but we need to feed Google Maps WGS84 data. For now those guides have to use force_wgs84 and have their points out by some 10s of metres.

https://secure.mysociety.org/cvstrac/getfile/mysociety/perllib/Geo/HelmertTransform.pm?v=1.4 is a possibility but this is released under a licence which may not be DFSG free so not something we want to use.

Nick has volunteered to port his Python implementation if needed.

I have now agreed to upload Geo::HelmertTransform? to CPAN so will be able to address this ticket once I've done that.

Andy Armstrong has code for this too so this may wait for that to happen.

If you install (the fixed version - attached to ticket) Geo::HelmertTransform?, and set your geo_handler as required, then OpenGuides will now convert properly, and your google maps will be in the right place
