84. Formats and conversion guidance
http://digimap.edina.ac.uk/webhelp/os/data_information/data_formats/new_data_tran
slators.htm

85. Data Download
• Data Download
has 5 categories of
data
• Click + or on
Category name to
open

86. 1. OS MasterMap
• Most detailed mapping available of GB
• Ordnance Survey have 4 layers of
MasterMap data (Topography,
Imagery, ITN and Address Layer)
• Digimap offers two of these layers:
• Topography layer
• Integrated Transport Network (ITN) layer

esurvey.co.uk/osweb
site/products/os-
mastermap/index.ht
ml

89. Using OS MasterMap in ArcGIS
• OS MasterMap supplied in GML format (within a Gzip file)
• Can import this directly to ArcMap…but In our experience it is trickier to
isolate features, analyse the data, change the style when using this
method. We recommend that you convert the data if possible.
• Conversion options?

90. OS MasterMap conversion
Possibilities:
1. Convert to ESRI
Geodatabase format using
Productivity Suite (ArcGIS
V9.2 or later) or Map
Manager (ArcGIS V9.1 or
earlier)
2. Convert to Shapefile
format using InterpOse

91. OS MasterMap Convertor
• Available through Eduserv CHEST:
• ESRI Productivity Suite (ArcGIS V9.2 or later)
• Map Manager (ArcGIS V9.1 or earlier)
• Converts OS MasterMap data to ESRI Personal Geodatabase format
• Accepts GZip files for conversion

92. InterpOse Digimap edition
http://www.dottedeyes.co.uk/spatial_data_loading/interpose/digimap.php
• Free download, which converts MasterMap GML data to SHP file format (and
various other formats)
• InterpOse accepts GZip files for conversion

93. 2. Backdrop mapping
•Largest scale at top
•Raster data all supplied in TIFF
image format, with a TFW file
•TIFF World Files contains location,
scale and rotation of TIFF map. Keep
in same folder as TIFF
•All compatible with ArcGIS, no
conversion requirements

94. 2. Backdrop mapping
• Information boxes
indicate:
– Scale
– Format availability
– Version
– Data Allowance
– Terms of use
• Version and format can
be changed in order
Basket, under options

95. 3. Land and Height data
•PROFILE 1:10000, created
2009. Contours at 5m intervals
with spot heights.
•PANORAMA 1:50000, created
1996. Contours at 10m
intervals with spot heights.
•DTM – Digital terrain model –
3D representation of terrain
surface.

96. 3. Land and Height data
• Contours, Panorama
available in DXF, NTF
formats
• DTMs available in DXF,
NTF, ASC, TIFF
• DXF AutoCAD format,
can import to ArcGIS
but…
• NTF can be converted to
ESRI Geodatabase, with
Productivity Suite

97. Productivity Suite, NTF Convertor
• Converts NTF data to ESRI Personal Geodatabase

98. 4. Vector Data
• Formats available for products not
consistent, e.g.:
– VectorMapLocal – GML
– Strategi – SHP, DXF, TAB, NTF, MIFMID
• SHP available for all vector maps,
except VectorMapLocal and
Meridian 2 Tiles (NTF, DXF)

99. Vector data formats
Format Compatibility
SHP Shape file, ArcGIS format
MIF/MID MapInfo format
NTF National Transfer format, non-proprietary
GML Geography Markup Language
DXF Drawing Exchange Format, AutoCAD

100. Shape files
• Shape files do not require any conversion prior to use in
ArcGIS.
• Remember to keep all constituent parts together - SHP, DBF,
SHX:

101. OS VectorMapLocal
• Free convertor
– GML to SHP –
from Rolta
• http://www.rolta-
europe.com/osvecto
r.html
• Digimap will
start to supply
VML in SHP in
near future

102. 5. Boundary and Location Data
• Boundary-Line - administrative
boundaries e.g. counties, unitary
authorities, electoral areas
• Code-Point – coordinates for
postcodes, boundaries for
postcodes
• OS Locator – gazetteer of road
names
• Entire 1:50000 Scale Gazetteer,
260,000 entries

105. Code-Point with Polygons
• Code-Point polygons are digital post-code boundaries
• Image shows Code-Point data and Code-Point Polygons, on 1:10000 Scale Raster
background

120. Sub-folder contents
• This example is a raster map data product. Note TIFF file and
TFW files.

by the Digimap licence OR the OS OpenData licence. So each
data folder has a conditions document that specifies which
conditions apply.

121. Unzip MasterMap zip files

• Vector data (e.g. OS MasterMap, OS VectorMap Local) will not
have the same appearance as it does in Digimap, when initially
added to ArcMap

123. Styling options
