1 What OS data is available in Digimap? How do I unzip and convert the data for ArcGIS? What is ArcGIS? Styling options Digimap OpenStream Other resources Using data from Digimap in ArcGIS

2 Data in Digimap – whats available? MasterMap vector data, GML format Administrative boundaries and postcode data Range of OS map data: Backdrop maps Land & height data Vector data Place name and road name databases

3 Data in Digimap – 2 types

4 Data Download - raster data

5 Data Download – Land and height data

6 Data Download - Vector data

7 Data Download - Location data

8 MasterMap Download Most detailed mapping available of GB Scale 1:1250 to 1:10000 Widely used by architects and planners NOTE: MasterMap Download provides vector format MasterMap. Raster format MasterMap is available in Data Download.

9 MasterMap Download 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

10 Boundary Download products Code-Point – postcode listings or postcode polygons Boundary lines – e.g. counties, unitary authorities, electoral areas National GB boundaries

11 Code-Point Code-point data, on 1:10000 Scale Raster background

12 Code-Point Polygons Code-Point data and Code-Point Polygons, on 1:10000 Scale Raster background

13 Boundary lines sample Raster map of Edinburgh Scotland constituency boundary lines overlaid

14 What OS data is available in Digimap? How do I unzip and convert the data for ArcGIS? What is ArcGIS? Styling options Digimap OpenStream Other resources Using data from Digimap in ArcGIS

15 How do I use this data in ArcGIS? 1. Download data from Digimap (zip file) 2. Process the data 3. Import data to ArcGIS 4. Analyse data / Create map a.Unzip data file b.Convert the data to a format compatible with your software - if necessary

16 Unzipping standard Digimap zip files Use the standard Windows unzip facility:

17 Unzip standard Digimap zip files

18 Unzip MasterMap zip files Data is delivered in GZip file - GML data within the Gzip Can extract the GML file from the Gzip file…not always necessary to do this

19 Data in Digimap - what formats? GML SHP, NTF, CSV, MIF/MID TIFF, SHP, NTF, GML, MIF/MID, DXF, CSV, ASC

20 Data in Digimap – what formats? Some products are available in more than one format, e.g. Strategi is available in NTF, DXF, SHP and MID/MIF

21 What formats are compatible with ArcGIS? Raster data products are available in TIFF format Compatible with ArcGIS

22 What formats are compatible with ArcGIS? TIFF World files - contain the location, scale, and rotation of a map that is stored as a TIFF image. Remember to keep the supplied TIFF files and the TFW files in the same folder! Otherwise your GIS software cannot locate the TIFF geographically.

23 What formats are compatible with ArcGIS? Shape files do not require any conversion prior to use in ArcGIS. Remember to keep all constituent parts together - SHP, DBF, SHX:

24 What formats are incompatible with ArcGIS? –NTF: OS Land-Form Profile – convert to ESRI Geodatabase OS Land-Form Panorama – convert to ESRI Geodatabase OS Meridian 2 – SHP files available OS Strategi – SHP files available OS Code-Point – CSV files available OS Boundary Line – SHP files available –GML: OS MasterMap, OS VectorMap Local

25 NTF data Convert to ESRI Personal Geodatabase format (.MDB suffix), using Productivity Suite or Map Manager (ESRI tools). Original file from Digimap Converted file for use in ArcGIS

26 Productivity Suite, NTF Convertor Available through Eduserv CHEST:Eduserv CHEST –ESRI Productivity Suite (ArcGIS V9.2 or later) –Map Manager (ArcGIS V9.1 or earlier)

27 GML data 2 data products are in GML format: 1.OS MasterMap data 2.OS VectorMap Local data It is possible to import GML/GZ files to ArcMap 10. However, 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.

28 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

29 Productivity Suite, OS MasterMap Data Convertor Available through Eduserv CHEST:Eduserv CHEST –ESRI Productivity Suite (ArcGIS V9.2 or later) –Map Manager (ArcGIS V9.1 or earlier)

30 OS MasterMap Convertor Converts OS MasterMap data to ESRI Personal Geodatabase format Accepts GZip files for conversion

31 InterpOse Digimap edition Free download, which converts MasterMap GML data to SHP file format (and various other formats) InterpOse accepts GZip files for conversion

32 OS VectorMap Local conversion Free download: Converts OS VectorMap Local to Shape file format Accepts GZip files

33 Gazetteer data – available in Data Download Delivered in CSV file Saved as DBF IV, using Excel 2003 N.B. DBF IV option not available in Office 2010 – try Open Office spreadsheet

35 What is ArcGIS? Desktop Geographic Information System 3 levels of license Applications within license: –ArcMap explore/analyse data and make maps. – ArcCatalog data management –ArcToolbox tools for data/spatial analysis

36 ArcMap Map display panel Table of contents – view data layers Toolbar – open ArcCatalog and ArcToolbox here

38 Appearance of vector data 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 MasterMap data viewed in ArcMap

39 Appearance of vector data Possible to apply style (or symbology) files to the data, to replicate the Digimap style

40 Symbology, or style, files InterpOse – provide style files for use with ArcGIS and MapInfo, which can be installed to your computer on setup of InterpOse Rolta - provide style files with the installation Productivity Suite, Map Manager – style files supplied EDINA supply style files for several data products – find these in the Help pages.

41 EDINA Symbology, or style, files OS data: –MasterMap, Strategi, Land-form Panorama, Meridian, Land-Line – in Help under Using data with ArcGIS 9.x Geology Digimap – bundled with data download file. 1 avl file for each Shape file. Marine Digimap – download Fonts files and Style file from Marine Digimap Help pages and copy into relevant folders in C:/Program Files.

43 Digimap OpenStream

44 Free service to anyone with.ac.uk address Must register to use the service Allows users to stream certain OS data sets directly to their software without downloading and storing large quantities of data Digimap OpenStream provides access to the following OS OpenData products: –MiniScale® –1:250,000 Scale Colour Raster –OS Vector Map District (Raster) –OS Street View®
