Data source

OS Street View is generated from a point and line (or vector) dataset nominally created at 1:10 000 scale, and this was first produced in November 2002. The OS Street View product has no paper published map origins.

The product is produced from an automated generalisation process using Ordnance Survey large‑scale datasets, which the production area then edit and edge-match the resulting data. A further automated process is applied that generates the finished product in a range of transfer formats.

Data Structure

Raster

Scale

The nominal scale of OS Street View is 1:10 000.

Recommended minimum to maximum scale range for viewing is 1:5 000 to 1:15 000 scale.

It is best viewed between 1:7000 and 1:10 000 scale.

Transfer format

• JPEG
• TIFF 8 bit LZW compressed
• TIFF packbit compressed

Colour options

OS Street View is supplied in colour and has the additional feature of an editable colour palette that enables users to be able to change the colours of features to match their own specific requirements.

Colour is used for line and polygons to help with the cartographic interpretation of features with:

• Settlements – brown stipple infill.
• Water features and sea areas, including text – blue.
• Vegetation – green.
• Roads – blue, red, yellow, grey according to their road classification.
• All other features – black.

The product is not available in black and white but a high-quality alternative to black and white raster data is to use a geographical information system to convert the colour data to a greyscale format.
