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

Onward use of data: considerations Download data file 1.Unzip the Digimap data file 2.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 Process the data Import data to software Analyse data / Create map

Data in Digimap – 2 types

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.

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

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