Hi Jim,
yes, my set-up is pretty much the same except that both quality parameters are set to V.

I think the problem may lie in the NBN Exchange format XML file where there is a line in the query that says

"and (s.entered_sref_system ilike 'osgb' or s.entered_sref_system ilike 'osni' or s.entered_sref_system = '4326' or s.entered_sref_system = '27700')"

I would hazard a guess that the "osni" should read "osie" but again I'm only guessing.

Roll on the Advanced training!!

Thanks,
Fiona

Hi Fiona,

I'd say that is a pretty well informed guess! Your update was posted while I was trying to reply but I will continue as I don't think John has quite bottomed this one out.

The NBN exchange format only admits the projections OSGB, OSNI, OSI, plus lat/long with datum WGS84 or OSGB1936 so the NBN Export report has to filter records accordingly since Indicia can support any number of projections which can be added as optional modules.

Indicia uses slightly different names for the projections so the report also has to rewrite the projection names which results in the following (from inspection)

Indicia   Report 
4326      WGS84
27700     OSGB1936
osgb      OSGB
osie      OSIE

Is that right? Do you have OSIE in your report output? That would not be a valid output. It should be OSNI or OSI but which?

I always find it very confusing trying to disentangle different projections and this is not helped by the fact that OSI is an ambiguous name as far as I can see. An EPSG number is more helpful. Maybe the NBN define what they mean more precisely elsewhere.

I wrote the sref_osie module and my understanding was that OSNI, the Northern Ireland grid (EPSG:29901), had been replaced by an all Ireland  grid and, in particular, a 1975 adjustment was in use (EPSG:29903, I concluded). Consequently I didn't create an osni module.

However, I see that John made a change to the module some time back that may actually mean that the module is working in OSNI.

I have 2 adjacent maps in my hand.
Ordnance Survey of Northern Ireland Discoverer Series 1:50000 Sheet 27 copyright 2004. Reference System: Irish Grid, Geodetic Datum: Irleand 1965.
Ordnance Survey Ireland Discovery Series 1:50000 Sheet 26 copyright 2004. Transverse Mercator Projection. Airy modified spheroid 1975.
They join up fine. Are those two different ways of defining the same grid?

The Irish Grid is fabulously documented but my current grid reference is somewhere out at sea. Does any of this matter? At 1:50000, I detect no difference between grid refs from your form and the map in my hand.
