Topic: Lat Long conversion issue?

I was checking some of my records in QGIS and loaded them using Sample.Lat and Sample.Long as the coordinates. However all the records are displaced about 80m to the ENE. See the image. The records near to Chanonry Lighthouse were not there but in the roundabout shown to the west. All the records shown along Ness Road where actually along the coastline at a similar displacement. So from the Sample table, Recorder converted NH74855566 to and Lat and Long of 57.573873558833, -4.09286931177761 which not where NH74855566 is. If I convert the same grid reference at https://webapps.bgs.ac.uk/data/webservi … gToLatLng, I get a lat and long of 57.573610, -4.094247 which is correct.

Re: Lat Long conversion issue?

Hi

Recorder 6 uses OSGB 36 Lat/Long not WGS84 which may be where the issue is. GIS systems should be able to handle this as long as you are aware of it.
