Old and new, good and better with Image comparison

In many cases it is useful to be able to compare situations quickly and easily. This can be geographic maps on which existing and new situations have been drawn or photos of an old and new situation. This can also concern existing and future situations where the future situations are projected on a photo. The future situation then comes from a 3D model, for example.

In the example below, an aerial photograph of an earlier situation in Sochi is compared with the situation after the realization of the infrastructure, stadiums and buildings for the Olympic Games in Sochi in 2014.

Sochi before the Olympic games

Sochi after the Olympic games

The use of images to compare situations can be of value in all kinds of reports. Consider, for example, environmental impact reports that provide insight into the effect of, for example, the placement of wind turbines on the landscape. This naturally places demands on the visual assemblies.

The purpose of verified visual montages, or sometimes referred to as Accurate Visual Representations, is often used in planning and environmental impact assessment and is intended to impartially represent the proposed development as it would actually be expected.
