It is not always easy to obtain 3D data on some of the city’s sites. Furthermore, these sites can be extremely difficult to reach. If overflight is permitted in the area, a drone survey is an interesting solution.
In this case, we are in the Grand Bay area of Mauritius. Because of the dense urbanization and the importance of vegetation cover, surveying from the ground is nearly impossible. Continuer la lecture de Photogrammetry from Drone→

The Quadracci Pavilion is the iconic sculptural addition to the Milwaukee Art Museum designed by the Spanish architect Santiago Calatrava. Highlights of the building, completed in 2001, are the magnificent cathedral-like space of Windhover Hall, with a vaulted a 90-foot-high glass ceiling; the Burke Brise Soleil, a moveable sunscreen with a 217-foot wingspan that unfolds and folds twice daily; and the Reiman Bridge, a pedestrian suspension bridge that connects the Museum to the city.

Photogrammetric surveying of ships is a complex exercise due to the nature of the objects to be recorded. The advantage of a complete survey, as opposed to a half-hull survey, is that it allows the deformations of the structures to be identified, evaluated and diagnosed.
In the example below, the demonstration is made on a model. The principles and difficulties are identical to a 1:1 scale model, but with much better accessibility. For examples of real boats, see the following pages
