    Photogrammetric monitoring of an artificially generated shallow landslide
    (Wiley-Blackwell, 2013-06) Akça, Mehmet Devrim
    An artificial rainfall event was applied to a forested slope in Ruedlingen, northern Switzerland. The experiment triggered a landslide which resulted in mobilising about 130m3 of debris. The event was monitored by a photogrammetric network of four cameras, operating at 5 to 8 frames per second, in order to quantify spatial and temporal changes by tracking tennis balls pegged into the ground. Image measurements were performed using automated image matching methods, implemented through a software package developed in-house. Three-dimensional coordinates of the target points were estimated by running a customised type of bundle adjustment, achieving a positioning precision of +/- 1 center dot 8cm.

The goal of the system is to assign daily tasks, receive completed tasks and in formations, inform workers about task changes, and send new tasks to the workers. Mobile Workers send their completed/updated tasks, and GPS positions, which is received from Bluetooth GPS receiver, to Server-Side application, which is stored in company center by using Client-Side Mobile Application on PDA devices at predefined times over GPRS Connection.
