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
