Unveiling a new London

Promap is pleased to provide instant access to an alternative source of mapping for London provided by The GeoInformation Group.

What is UKMap®?

How has UKMap® been created?

UKMap®’s topographic features have been digitised at 1:250 scale using high resolution aerial photography.

The aerial photos were orthorectified using a GPS and a detailed terrain model from Cities Revealed® LiDAR database. This gave an accurate basis from which the mapping could be digitised.

All features within the photo were then digitised, such as fences, buildings, road markings, trees, bridges etc. using the most up to date digitising tools to ensure parallel lines, right angled corners and splines for curves were created accurately. This all makes for a neater, accurate and cartographically sound map base.

The maps were then sent out to a team of dedicated field workers who walked every street, park and industrial estate; in fact everywhere with public access, in order to collect the content of the mapping. This content included the collation of house numbers, street names, shop names, locality information, office names etc. The data was then added to the digitised map layer of UKMap®.

Over 30 people were involved in collecting fieldwork data in London during the 15 months it took to complete a street by street survey and completed some 60,000 pieces of paper.
