“Created using the latest Photogrammetric 3D technology and the highest resolution aerial imagery available our models are unparalleled in their accuracy. We have created a single block of imagery that covers over 45sq km of central London at up to 2.5cm/pixel resolution. Within this block we have used over 50,000 tie points and 251 ground control points, this ensures that any measurement taken is within 150mm of its real world location. In fact measurements taken by us have come in at an average tolerance of 40mm compared to a full measured survey. However please do not assume that we are limited to capturing models in London only, we can use the same principles for any UK, European or World Wide city. Our models are supplied geo-referenced and ready to be used within any CAD or GIS platform.”
