OS MasterMap® Topography Layer
is available in a number of different formats:
File Geodatabase - this
is a proprietary GIS data format developed by ESRI but can be read
by other GIS applications including QGIS.
Geopackage - is an open,
non-proprietary, platform-independent and standards-based data format
for geographic information system implemented as a SQLite database
container.
GML - Ordnance Survey deliver
OS MasterMap® Topography Layer
in GML format. This format can be read by most GIS/CAD applications
although steps are usually required to convert it in to a more usable
format.
DWG - this is the native
drawing format for AutoCAD although it can be read by most CAD applications
including Vectorworks and ArchiCAD.
How you get this data in to your GIS/CAD system depends on the format
of the data you have downloaded and the tools available to convert the
data. The tables below list suggested and alternative methods for each
of the main GIS/CAD packages.
ArcGIS
Suggested
Method
Download the data in File Geodatabase
format and open in ArcGIS through the Add Data button. No conversion
is required.
Alternative
Methods
Download
the data in GML
format then:
ArcGIS Pro users: use UK Data Loader
to load the data in to an ArcGIS Pro workspace, the password
to install UK Data Loader is provided with the data downloaded
from Digimap;
ArcGIS Desktop users: use Productivity
Suite to convert the data to geodatabase format;
ArcGIS Desktop users: convert the data using ArcToolbox
> Data Interoperability Tools > Quick
Import;
use the Add Data button to display
the GML directly.
AutoCAD
Suggested
Method
Download
the data in DWG
format and then open in AutoCAD. No conversion is required.
Note this data has a default representation and attributes are
stored as extended object data, xdata
Alternative
Methods
If
you want more control over the imported data or want to view attributes,
you should download the data in GML
format then use one of the methods below:
Download the data in GML format
and then import in to MapInfo using the Table
> Import command.
Alternative
Methods
Download
the data in GML
format then:
use OSM2MIF to convert the data
to MIF/MID, then use the Table > Import command to convert
the MIF/MID to TAB format.
QGIS
Suggested
Method
Download the data in Geopackage format
and open in QGIS through the Add Vector Layer function. No conversion
is required.
Alternative
Methods
QGIS
is able to read a number of common GIS formats including GML,
File Geodatabase and Shape. Alternative methods are listed below:
Download the data in GML
or File Geodatabase
format and open through the Add Vector Layer
function. No conversion is required. Note: File Geodatabases
cannot be edited in QGIS.
OS MasterMap® Integrated Transport Network™ (ITN) Layer
OS MasterMap® Integrated Transport Network™ (ITN) Layer
is available in GML format. In order to build a topological network from
the data we recommend using the following tools:
other GIS and CAD packages may be able to read the raw GML data.
