The translators on this page are freeware. They are available to all users at no charge. The programs may be distributed to others but no charge (other than media costs) may be made. They have been provided as contribution to the GIS community.

These programs have been written by Nigel James

You can download the following applications

	NTF2MIF New Version available	NTF2MIF translates Ordnance Survey NTF files into MapInfo Interchange Format (MIF). It is the only free NTF to MapInfo translator available which supports all data sets available through Digimap. Version 3.5 now available Updated April 2007. NTF2MIF now translates CODE-POINT NTF

	OSM2MIF	OSM2MIF translates the new Ordnance Survey MasterMap data in GML format to MapInfo Interchange Format (MIF). MasterMap will be available to Digimap users in 2007 (from January for the early adopter sites and from September for all others). OSM2MIF translates all three MasterMap layers currently available (Topographic, Address and Integrated Transport Network). It can handle single files or multiple files by batch processing.This new version fixes errors occuring with polygons containing inner 'holes'. It also creates a new layer with topographic landforms (e.g: slopes). These are transparent so they can be overlaid on the topo layer. It is recommended that all users update their existing version.

		NOTE: OSM2MIF has been designed primarily for DIGIMAP users, many of whom do not have access to commercial translators. It has been tested with the sample data available on the OS website, but it cannot be guaranteed to work with gml produced by other software. Users are welcome to report any problems and where possible these will be accomodated in new versions of the program. For more information about MasterMap, see the Ordnance Survey website

	LL2DX F	LL2DXF is a free OS Land-Line NTF to DXF translator. It translates single tiles and batch-processes multiple tiles into separate DXF files. If you are a Digimap user who requires Land-Line in DXF, you can now download the NTF files and convert them easily and quickly to DXF! Version 1.3 is now available. If you have downloaded a previous version, replace it with this updated version.

	TOMS2XYZ	TOMS2XYZ converts Total Ozone Mapping Spectrometer data into a delimited text file containing lon, lat and value for each point, ready to use in a GIS or other software.

The following can be found on the GEO tools page

	Conversion Tools	UPDATED! MapInfo requires coordinates to be in decimal degrees (lon/lat) or metres (OS national grid). However your table may be in degrees:minutes:seconds or conventional (letters and numbers) OS grid format. These have to be converted to decimal deg. or metres respectively before you can map them. Conversion Tools is a free MapInfo tool which converts tables of lon/lat in conventional format into a mappable table with points in a single step. It also converts tables of British and Irish OS grid references in conventional letters and numbers format to mappable tables with points in the same way. You can also enter a single coordinate pair or OSNGR and plot it on a mapper. Conversion Tools is an essential add-in tool for MapInfo users. Updated 18.09.05

	Scale Finder	*Scale Finder converts linear scales to representative fractions and vice-versa.* It is an invaluable tool for cataloguers and map users.**

NTF2MIF - Ordnance Survey NTF to MapInfo MIF Translator - Updated 2007

Version 3.5 is now available - download it now!


Why do I need NTF2MIF? Ordnance Survey digital data (available from DIGIMAP) is supplied in NTF format, which MapInfo cannot import. NTF2MIF translates NTF data files into MapInfo MIF (MapInfo Interchange Format). MIF files can then be imported and opened in MapInfo. Once the files have been imported, they are saved as MapInfo tables (.tab files). What's new in Version 3.5? Code-POINt NTF is now supported Previous updates: Version 3.4: Boundary-Line added and minor bug fixes. Version 3.3: Improved handling of large data files. MIF syntax error in selective Strategi layer processing fixed. Version 3.2: New version of Meridian 2 now supported. Version 3.1: OSCAR datasets added Default folder for opening NTF files and saving MIF/MID files can be set.

Features: Multiple NTF files can be translated at once. Files can be merged to create a single, seamless MapInfo table. Text objects can be translated to a separate layer.True-type fonts can be used (to display cartographic symbology). Network data can be extracted from Meridian 2 and Strategi data. NTF2MIF is fast and easy to use and is the only free translator which translates all DIGIMAP data products. To download NTF2MIF, click here

Installing NTF2MIF

NOTE: If you have a previous version of NTF2MIF, uninstall it BEFORE installing the new version!

Download the .zip file to a temporary folder, unzip it, then run the file setup.exe to start installation. The program will by default create a folder in your program files folder and install itself. NTF2MIF has help which guides you through the simple steps to translate files. The installation files include a user guide in rtf format.

OSM2MIF - Ordnance Survey MASTERMAP to MapInfo MIF Translator

NEW Version 2.0 now available - download it now! This new version fixes errors occuring with polygons containing inner 'holes'. It also creates a new layer with topographic landforms (e.g: slopes). These are transparent so they can be overlaid on the topo layer. It is recommended that all users update their existing version.

Why do I need OSM2MIF?

Unlike Ordnance Survey Land-Line data (available from DIGIMAP) which is supplied in NTF format, MasterMap is in GML format. Versions of MapInfo prior to v 8.0 do not support the full import of OS gml. OSM2MIF translates MasterMap data files into MapInfo MIF (MapInfo Interchange Format). MIF files can then be imported and opened in MapInfo. Once the files have been imported, they are saved as MapInfo tables (.tab files).

Features:
OSM2MIF translates all three layers (topographic, address and ITN). Attribute data is maintained (currently not all routing data in the ITN layer is supported, but this may be improved in a later release). Update versions of MasterMap include Departed Members and a list of these can be extracted using OSM2MIF. Single or batch file processing is possible.

A free MapInfo tool (OSM Batch Import) is included - this will import all layers in a single operation.

Installing OSM2MIF

Download the .zip file to a temporary folder, unzip it, then run the file setup.exe to start installation. The program will by default create a folder in your program files folder and install itself. OSM2MIF has help which guides you through the simple steps to translate files.

LL2DXF - Ordnance Survey LAND-LINE to DXF Translator - New Nov. 2004

Version 1.3 now available - download it now!

Features:
LL2DXF translates OS Land-Line tiles in NTF format to DXF (AutoCAD release 12 compatible). Single tiles can be translated, or a batch of Land-Line NTF tiles can be converted in one go. DXF blocks (Land-Line features such as tree symbols, flow arrows etc) are created and colours are based on the OS specifications.

LL2DXF has been updated. The NEW Version 1.3 enables the output location to be changed when batch translating files and gives the choice of standard or descriptive layer names.. If you have downloaded the previous version, replace it with this updated version.

NOTE: If you have the previous version ofLL2DXF, uninstall it BEFORE installing the new version!

TOMS2XYZ - TOMS (Total Ozone Mapping Spectrometer) to delimited-text Translator - New 2004

Version 1.2 now available - download it now!

Features:
TOMS2XYZ converts data files downloaded from the Earth Probe TOMS (Total Ozone Mapping Spectrometer). Data is converted into tab-delimited ascii text format for easy use with spreadsheets, databases and GIS.

Features include setting bounds and ignoring '999'(missing or bad data) values. It handles all data types available.
