Introduction

This guide covers the import of MasterMap data to MapInfo. The guide specifically deals with MasterMap data that was initially downloaded from the MasterMap Data Download facility within Digimap’s OS Collection, in GML format.

NOTE:

MapInfo V8.0 or later

If you are working with MapInfo V8.0 or later, MapInfo will convert your GML data on import. You do not need to undertake a separate conversion process.

Go to Import GML data to MapInfo

MapInfo V6 or V7

If you are working with MapInfo V6 or V7, MapInfo will not allow you to import GML data.

You must convert the data to a compatible format prior to import. There are two free conversion tools available:

1. OSM2MIF from the Bodleian Library http://www.bodley.ox.ac.uk/guides/maps/translat.htm

2. InterpOSe from Dotted Eyes.http://www.dottedeyes.com/spatial_data_loading/interpose/digimap.php

For step-by-step conversion guidance, have a look at the Digimap training guide ‘Convert MasterMap for MapInfo’:
