If you display or use vertical mapping imagery of any kind, you ll probably have started to hear rumblings about the use of oblique imagery. The oblique image, which is an aerial photograph taken from an oblique angle (often from multiple oblique angles, to capture a full 3D dataset), makes the 2D aerial image come alive and makes it much more meaningful for a user.

2D images convey a great deal of information about the placement of buildings, objects, geological strata and other topographic features, in relation to each other. The oblique image adds a whole new level of meaning to that information. By gaining access to reliable oblique imagery, users are able to gain a clear picture of the buildings, objects and features they are examining in relation to their immediate environment.

This is particularly useful in planning applications, where a planning authority is able to determine not only the proximity of a proposed building to other civic amenities and existing infrastructure, but also to see how the existing buildings and amenities in the proposed area look. Seeing how they already look enables the authority to work out what visual effect a proposed new building may have on an area.

Oblique imagery can even eliminate the need for a site visit. Where measurements need to be taken, planners traditionally have to visit their sites to take proper measurements high quality oblique images make it possible to take the data directly from the pictures. Measurements can be made to ascertain the actual height of buildings, vegetative cover and street furniture.

When you lock your oblique image data into an existing software tool, you can start to make multiple comparisons of a single area by viewing it from different angles all at once. The software is able to automatically synchronise the positioning of up to five different angles, so you can get an extremely accurate overall picture of the area you are measuring and studying.

Oblique imagery can also directly power the creation of 3D building models. Using the software, a company or individual is able to render models of buildings from real life and export them for use in multiple applications.

Ultimately the advantages of using oblique images are best described by a comparison of the datasets. 2D aerial imagery is invaluable but gives a single plane of measurement. Oblique images are theoretically capable of allowing you to measure any elevation or angle of an existing object a virtually infinite number of datasets, which mean you can build up a hugely detailed picture of a place or a space.

The technology is new, but already quite familiar. You will, for example, have seen it on the real world street view type interactive maps promoted by major online information providers. With oblique imagery still in its infancy the application potential for the technology can only grow leaving one to look forward enthusiastically to the next step.
