Translation Software for OS MasterMap™
InterpOSe translates OS MasterMap™ into MapInfo and ArcView file
formats. OS MasterMap is from the Ordnance Survey DNF™ and is supplied
in a compressed GZ format, based on GMLv2. InterpOSe will translate
your initial supply and offer intelligent management of your ongoing
supply of "change - only" updates.
Operation
InterpOSe translates any number of files at the same time into a continuous
coverage. OS MasterMap is supplied in geographical "chunks"
of either 2km, 5km or 10km and in any combination of 9 themes. In OS
MasterMap, the entire land surface is covered by a blanket of polygons.
Each customer opts to receive polygons in either a "topological"
or an "independent" format – the result after translation
is the same for the initial supply. We recommend that you should request
"independent" polygons. The product does not use tiles, but
is supplied in chunks that contain all the features wholly or partly
within arbitrary squares. As a result, adjacent chunks contain duplicate
features. Features overlapping the edges of chunks are identified and
de-duplicated. Each feature is identified by its TOID™ (TOpographic
IDentifier) and version number. These are suitable for associating your
own information, and each feature includes comprehensive attribute data.
Benefits
-
Process a batch of chunks at the same time, with the option to
remove duplicate features.
-
No need to uncompress the GZ files you receive, as InterpOSe translates
them directly.
-
Use either polygon structure – we recommend independent polygons
for speed of translation.
-
Determine the sequence of multiple categories within an attribute,
by using precedence tables.
-
Construct and maintain a database containing the complete history
of changes for each feature.
-
Automatically apply change-only updates to all features that have
been amended or deleted.
-
Graphical style picker to symbolise each type of feature when using
MapInfo Professional.
-
Identify the effects of the positional accuracy improvement programme
and trigger ShiftWiz.
-
Wizard-based translation.
Compatibility
InterpOSe runs on Windows 95/98 or NT/2000 and outputs MapInfo TAB
files, ArcView SHP files or plain text MIF/MID files.
N.B. Translated OS MasterMap files are in the region of 10 times larger
than equivalent Land-Line files in MapInfo format.
