1 Digimap Training Workshops Ordnance Survey Products Aim: to provide support staff with a basic knowledge of Ordnance Survey digital mapping products

2 Digimap Training Workshops Objectives By the end of this session you will: –be familiar with types of Ordnance Survey data products –be able to identify the best product for a particular project –Know which products must be converted to a different format before being used in a GIS

3 Digimap Training Workshops Introduction Ordnance Survey map products can be downloaded from Digimap in a number of different formats for use in various geographical information systems (GIS), drawing, graphics and spreadsheet software Digimap's Data Download Service provides data in numerous formats. Information on each format is given in this presentation

4 Digimap Training Workshops Types of Ordnance Survey data Vector Data –MasterMap - Topography, buildings, land, roads, water features –MasterMap – Integrated Transport Network (ITN), roads, routing info –Land-Line.Plus ®, buildings, land, roads, water features –Meridian™2, roads, railways, administrative areas, water, woodland –Strategi ®, road-atlas type data, roads, railways, settlements –Land-Form PROFILE ™, detailed height data –Land-Form PANORAMA™ contours from the Landranger ® maps Raster Data –1:10000 Colour Raster, digital version of OS Landplan ® maps –1:25000 Colour Raster, digital version of OS Explorer ® maps –1:50000 Colour Raster, digital version of OS Landranger ® maps Gazetteer (place names) – names ( national coverage ) Code Point –National Grid references for each unit postcode in Great Britain Boundary Line –Administrative and voting boundaries in Great Britain

5 Digimap Training Workshops Vector Data A record of the coordinate positions of points and lines which when linked together in a computer provide a representation of the landscape. All points and lines are feature coded Software is required to display, manipulate, customise and plot map images from the data
