Border line between Wales and England

Added by Thomas about 1 year ago

I'm looking for the border line between Wales and England. As csv- or gmt-file. Where can I find that? Can someone help?

This might help, but it's all the border lines from the Ordnance Survey (web site says 330 MB, but it's more like 754 MB, in zipped format).

You can download the file in (say) ESRI format, then use gdal's ogr2ogr to convert the shape file into something GMT can use.

However, you may have to hunt down the particular boundary you need. Files are sorted by region and purpose.

After some further digging into this data set - which is undoubtedly useful for someone, maybe not scientists and researchers, I'm doubtful that this source is very helpful.

I used ogr2ogr to convert into GMT format and found that the coordinates were in a local UK coordinate system. To get lays/lons, you'd have to run these coordinates through GMT's mapproject command using the proper projection, ellipsoid, false eastings, etc. and associated parameters. Probably more bother than it's worth!

Apologies, if I led anyone astray!
