Most professional users are aware of the uses of vertical photography, Oblique imagery is aerial photography taken with an inclination of approx. 45º, allowing the users to visualise the facades of the buildings. The oblique images are easier to interpret by a regular user with no previous experience with aerial photography. Georeferenced oblique imagery extends the benefits of traditional vertical aerial imagery providing a unique perspective view of a locality, allowing users:
- To see sides of a feature, exposing blind spots, exits and entrances previously impossible to locate on vertical aerial imagery.
- The ability to measure the height, length & area of features directly from imagery.
- Improve the identification of hard to see assets and facilities (e.g. lamp-posts) which are difficult to distinguish on traditional vertical photography.
- View GIS data in 3D by draping it on the oblique imagery, extending the traditional and more familiar 2D view afforded by most GIS applications
Oblique imagery has been developed to complement the existing vertical ortho-photography, rather than replace it. Blom has captured every urban centre in Western Europe with a population of 50,000 inhabitants or more. This is the most comprehensive and detailed image database available worldwide.
