St Albans 2008-2025 diff map on 2025

3D ModelNoAI

This is a difference map between two models of the St Albans – one shot in 2008 and the later model shot in 2025. The colors indicate graphically the distance between corresponding points in the two models. Green is where they coincide and the hotter colors and colder colors are where they differ based on the signed difference i.e. which side of the reference model the other model lies. You can see depending on which model you choose as the reference the colors shift hot to cold or cold to hot. This one has the difference values on the 2025 model so areas that are missing show up on the layers below the missing deck or bottom.
