This importer will import MasterMap topographic, ITN and address data into SQL Server 2008, a Postgres database, or a map file such as ESRI Shape. The importer can be used in conjunction with products such as the UMN MapServer. The source for the importer is available and free for personal, trial and demo use.

Commercial terms are available below.

Features:

• Configurable database schema via XSD (XML Schema Definition).
• Configurable XSL transform based on Ordnance Survey style guide.
• Remove duplicates from adjacent tiles.
• Change Only Updates.
• High performance
• Bulk data load for SQL Server 2008, ESRI Shape or MapInfo MIF/TAB
• Accurate conversion of maps from OS grid references to Lat/Long using OSTN02

Zipped data is streamed through a compiled XSL transform into a bulk load or an ESRI Shape file.

Ordnance Survey have supplied an XSL transform which converts MasterMap data for display as an SVG in accordance with the OS style guide.  The transform applied by this software is based on that.

(In 2009!) on a reasonable machine, the importer takes 2 minutes to process 10Mb of zipped data.

We would expect it to process a 35Gb national dataset in 7000 minutes - 4.8 days.

• Change license to MIT
• Moved code to github

Configuring the importer

Resulting data as rendered by UMN MapServer

The Ordnance Survey style guide specifies vector symbols in SVG format. They are now available converted them to transparent PNG images, centred at the symbols origin using a meters based scale at resolutions of 1,5,10,25 pixels per meter.
