Hiya, welcome to OpenStreetMap and thanks for the edits you’ve made recently around Hornby :)

It looks like you’re quite keen to tackle bigger changes. There are a couple of things you should probably be aware of first:

1. There’s a tagging scheme for farmland which differentiates between pasture (grazing), uncultivated hay fields, and higher productivity ryegrass hay/sileage fields. While it can be a bit hard to tell the usage of a field from aerial imagery (and they do change over time), if you have some local knowledge it should be possible to tag a field appropriately for its predominant use. See https://wiki.openstreetmap.org/wiki/User:Gurglypipe/landuse

Your username suggests you know a thing or two about farming. Is that the case? :) If so it would be wonderful to have your input.

2. The aerial imagery is unfortunately not perfectly aligned to ground truth. If you’re going to add significant new amounts of geometry, or realign existing geometry, please check the imagery is aligned before starting. Turn on the ‘OSMUK Cadastral Parcels’ overlay in the ‘Background Settings’ on the right, and adjust the ‘Imagery Offset’ until the aerial imagery matches the Cadastral Parcels in a few key areas. I find fence junctions or house boundaries are easy to align.

The alignment is normally up to about 2m out in either direction in this area of the North West, and it varies by area, so needs to be re-aligned every time you start editing a new area.

I think the alignment for Hornby itself is 0.14,-1 with the current Bing imagery.

I hope that makes sense, and sorry to introduce this all at once — I just wanted to make you aware of it before you create loads of fields which are all misaligned from ground truth! Happy to answer questions if you have any :)
