The privacy of source code makes, in many situations, commercial application software unable to academic purposes. Such applicative programs are like “black-boxes”, allowing only data input and results output, as a function of the graphical user interface manipulation. It strongly hinders their application to education, since users remains alienated of what exactly is performed in the applicati...

Flooding is a major problem for many countries causing damage to the environment and pressures on human activity. Engineers use Manning’s coefficient of roughness to determine water flow over floodplains which is a vital parameter in hydrodynamic studies. The coefficient is mainly a property of the ground surface texture and the changes in water surface elevation. The traditional method of dete...

Three dimensional architectural models are more and more important for a large number of applications. Specialists look for faster and more precise ways to generate them. This paper discusses methods to combine methodologies for handling data acquired from multiple sources: maps, terrestrial laser and additional measurements, together with digital images for the purpose of generating the 3D vis...

The lack of detailed life history (LH) information (e.g. age, growth, size at maturity, sex composition etc.) for many species of conservation importance limits the implementation of appropriate conservation measures. Typically, LH information is acquired using lethal sampling techniques, which undermines the goal of conservation. This is particularly problematic for many shark species that hav...

Introduction: Immobilization in a hip spica cast is required in surgical and nonsurgical treatments for children aged three months to four years diagnosed with developmental dysplasia of the hip. Skin complications are associated with the use of the spica cast in 30% of the cases. This research explores the use of photogrammetry and rapid prototyping for the production of a lighter, shower frie...

Morphological features correlate with many life history traits and are therefore of high interest to behavioral and evolutionary biologists. Photogrammetry provides a useful tool to collect morphological data from species for which measurements are otherwise difficult to obtain. This method reduces disturbance and avoids capture stress. Using the Galapagos sea lion (Zalophus wollebaeki) as a mo...

In Aerial Photogrammetry some tools are available to simplify the aerial mapping planning and make it faster. In particular, once defined the scale of the map, witch is related to the Spatial Resolution (SR), diagrams are available to provide the average scale of photogram and the flying height for different focal length values. Terrestrial Photogrammetry is deficient in this kind of tools, pro...

The Haghia Sophia in Istanbul belongs with its unique dome construction to the outstanding and extraordinary architectural structures in the whole world. Built between 532 and 537 during the Byzantine Emperor Justinian (527565), it reflects the sum of all experiences and knowledge of the classical antiquity and it is one of the important monuments of the world heritage. Nowadays the building is...

This paper describes the project of the Close Range Photogrammetry and Remote Sensing Group, University of Vigo, Spain, involving historic arch bridges in Galicia, Spain. The first aim of this Project consists on building a database of the historic arch bridges in Galicia, documenting location, surroundings, geometry, singular characteristics, structural faults, building material and state of c...

The high complexity of modern large scale construction projects leads their schedules to be sensitive to delays. At underground construction sites the earthwork processes are vital, as most of the following tasks depend on them. This paper presents a method for estimating the productivity of soil removal by combining two technologies based on computer vision: photogrammetry and video analysis. ...
