Malcolm,
Our PolyWiz product is produced specifically for this purpose. It
automatically builds all possible regions from the relevant line features
and matches with seed points to determine which polygons are buildings,
water areas and roads (the latter using the road centre-lines). You may
feed in a table of additional lines, for example to close gaps in road edges
or split the road layer into separate polygons.
Full details are on our website at http://www.dottedeyes.com/polywiz.htm
With very best wishes
Leslie Last

Subject: MI Polylines to Polygons
> Hi all,
>
> We are looking to convert our Ordnance Survey 1250 landline data from
> polylines into closed polygons/regions and then separate the data into
new
> datasets using the OS 'feature code' field (a numeric field).
>
> Does anyone know of a mapinfo application (free or commercial) that will
> enable us to carry this out in house and from within the mapinfo platform.
>
> If it produces information that is compliant with British Standard BS7666
> 'the National Land and Property Gazetteer' all the better.
>
> We are currently running ver 5.5 (upgrading to ver 6.0 soon).

> Many thanks
