  1. Onward use of data from Digimap Collections Carol Blackwood Vivienne Carr

  2. Meeting content • Considerations in use of data • Unzip data • Data formats • Data conversion • Using data in ArcMap: adding data, amending symbology (Desktop sharing) • Resources • Q&A

  3. Meeting content • Considerations in use of data • Unzip data • Data formats • Data conversion • Using data inArcMap: adding data, amending symbology (Desktop sharing) • Resources

  4. Downloading data from Digimap Collections I’ll login to one of the Data Download services EDINA servers – hold data for 4 Digimap Collections 1. Search Returns a data.zip file Download data file

  5. Onward use of data: considerations Process the data Import data to software Analyse data / Create map Download data file • Unzip the Digimap data file • Convert the data to an appropriate format if necessary – consider formats and conversion options • E.g. ArcGIS or MapInfo, CAD or Image software • Your data will NOT look as it does in Digimap

  6. Meeting content • Considerations in use of data • Unzip data • Data formats • Data conversion • Using data inArcMap: adding data, amending symbology (Desktop sharing) • Resources • Q&A

  7. Unzip Digimap data.zip files Data download: 1. Data.zip 2. Unzip data.zip: Contents.txt, Conditions.txt, Data files

  8. Unzip OS MasterMap data files 2. Unzip data.zip: 1. Contents.txt 2. Conditions.txt 3. TOID list.txt 4. How to use the data .html 5.GZip data file 1. Data.zip 3. Unzip GZip data file: GML data file

  9. GZip files Windows standard unzip will not work – try: • Gzip • WinAce • Stuffit • PowerArchiver • WinRAR • WinZip • WinImp • 7-zip

  10. Meeting content • Considerations in use of data • Unzip data • Data formats • Data conversion • Using data inArcMap: adding data, amending symbology (Desktop sharing) • Resources • Q&A

  11. Data in Digimap – 2 types

  12. Raster data formats • Digimap raster data are supplied as TIFF files. • TFW files also supplied. • Most GIS or CAD software will accept TIFF image files, with no need for conversion. • Remember to keep the supplied TIFF files and the TFW files in the same folder! Otherwise your GIS software cannot locate the TIFF geographically.

  13. Vector data formats • DXF (Drawing Exchange Format) • NTF (National Transfer Format) • GML (Geography Mark-up Language) • SHP (ArcView Shapefile) • MIF/MID (MapInfo export format) • Not every product is available in every format • Some data formats may be incompatible with software e.g. NTF, GML, DXF

  14. Meeting content • Considerations in use of data • Unzip data • Data formats • Data conversion • Using data in ArcMap: adding data, amending symbology (Desktop sharing) • Resources • Q&A

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

  16. ArcGIS – common conversion requirements

  17. ArcGIS conversion tools • Available through CHEST: • ESRI Productivity Suite (ArcGIS V9.2 or later) – this must be requested from CHEST separately, via your institutional CHEST representative. • Map Manager (ArcGIS V9.1 or earlier) • InterpOse Digimap edition - free download for GML data: • http://www.dottedeyes.co.uk/spatial_data_loading/interpose/digimap.php

  18. MapInfo – common conversion requirements

  19. MapInfo conversion tools • NTF2MIF - free download for NTF data • OSM2MIF - free download for GML data • Both available from: http://www.bodley.ox.ac.uk/users/nnj/translat.htm • InterpOse Digimap edition - free download for GML data: http://www.dottedeyes.co.uk/spatial_data_loading/interpose/digimap.php

  20. CAD conversion tools • InterpOse Digimap edition - Converts GML to DXF format: • http://www.dottedeyes.co.uk/spatial_data_loading/interpose/digimap.php

  21. Meeting content • Considerations in use of data • Unzip data • Data formats • Data conversion • Using data in ArcMap: adding data, amending symbology (Desktop sharing) • Resources • Q&A

  23. Resources EDINA: • Help pages– Using data with GIS • Training guides: http://edina.ac.uk/digimap/support/training/

  24. Resources EDINA Symbology files: • OS data: • Strategi, Land-form Panorama, Meridian, Land-Line – in Help under Using data with ArcGIS 9.x • OS MasterMap – will be added to Help shortly • 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.
