Map records as squares displaces 10 figure grid refs by 0.5 metres #16

From an email from Eric Fletcher (Cheshire Record)

I am not sure why I haven’t noticed this before now, but it seems that when I have imported Rec6 data into QGIS using TomBio it has displaced the 10 figure squares to the north and east by half a metre, or so it would seem. All other resolution data seems to display correctly. I have been using a dataset for the zoo estate and it contains 4, 6, 8 and 10 figure references.

I have attached an image that gives an example of the issue. <<< chester zoo estate_species distribution map zoomed_oct 2017

This is a definite bug Eric. Looks like a rounding error possibly. I have verified it with some dummy data. I will address this when I next work on the software. Is this causing you a real problem at the moment?

Hi Rich, thanks for this. It isn't critical for us at the moment, we are just producing some general distribution maps and they are at a fairly coarse resolution.
