I was thinking of a different possible project which perhaps we can
postpone until a different quarter rather than starting today.
There are a lot of buildings which have been traced from various imagery
layers but with no other useful information on them. Is it a shop, a
house, what is its address, etc?
I was going to suggest that we spend three months trying to gather the
address information for such buildings, and at the end of the quarter
remove all the others to give us a better idea of how complete the map
is. If we just want approximate building shapes we’ve got OS OpenData
for that. At the moment they give a false impression of completeness,
and also make it harder without zooming in to work out which areas still
need a proper survey.
I vote against that. Outlines traced (with appropriate care) from
imagery will often be more accurate than OS OpenData outlines.
If the project proves successful we could extend it to farmland areas
where hedges and fences haven’t been added to break up the area.
I know several places round here where there is no hedge, fence or any
other substantial boundary between fields: the farmer just leaves an
uncultivated strip.
