It's great that you want to add to the map data. Please do not add the
OS OpenMap Local building outlines. They are heavily simplified and as
such, poor quality. You can't distinguish how many residences there are
in a building outline, so is it detached, semi-detached or a terrace?
Adding buildings is valuable, but I believe in quality not quantity, so
I would trace building outlines from aerial images and not import the
'dumbed-down' OS Open data. Let's make the best map we can, not just
import OS's deliberately reduced quality stuff.
Cheers,
Chris (chillly)
BTW, this list list is almost dead. If you really want to reach people I
would use talk-gb.

Hi,
I am proposing to do some mapping in a couple of parishes in North
Lancashire. These are "Slyne-with-Hest" and "Nether Kellet". I plan to
use the latest OS OpenMap Local dataset to provide basic building
boundaries where none previously exist. I will be using OSTN02 data to
do the transforms.
Any comments or suggestions gratefully accepted.
Roger
