Depression filling and direction assignment over flat areas are critical issues in hydrologic analysis. This paper proposes an efficient approach for the treatment of depressions and flat areas, based on gridded digital elevation models. Being different from the traditional raster neighborhood process which is time consuming, a hybrid method of vector and raster manipulation is designed for dep...

Context: Glenohumeral and scapular upward rotation are important factors in functional upper extremity motion. Objectives: To determine how different amounts of glenohumeral rotation (internal, external, and neutral) affect scapular upward rotation. Design: Controlled laboratory study. Independent variables were the amounts of internal, external, and neutral glenohumeral rotation. The dependent...

According to the perception that subjects have about geographic objects, people can evaluate their proximity. The answers to the question if a geographic object is near other will be different according to the environment that the objects belong to. Also, when we consider geographic objects that do not have well defined boundaries, the perceptions of people with respect to the distance will be ...

Accuracy assessment of a global digital elevation model (DEM) is an important and challenging task primarily because of the difficulties and costs associated with securing a reliable and representative reference dataset. In this article, we report on the vertical accuracy assessment of the WorldDEMTM, the latest global DEM using the synthetic aperture radar interferometry (InSAR) method, based ...

In the analysis of terrestrial laser scanning (TLS) data the digital terrain model (DTM) is one of important elements. To evaluate the DTM or to find the DTM by way of optimization it is necessary to formulate the measure of DTM quality. Three parameterized measures are proposed and tested against a comparative model for a series of TLS data. The measure equal to the number of points inside a l...

E-Learning beginnt, von der euphorischen Phase in die alltägliche Praxis überzugehen. Hierfür sind Kriterien zur Nutzung der neuen Medien zu präzisieren und in Veranstaltungseinheiten einzufügen. Solche Bedingungen und Forderungen aus dem Projekt SIMBA werden in diesem Artikel vorgestellt, wobei als Zielgruppe Studentinnen der Informatik gewählt wurden. Die konkrete Umsetzung wird anhand eines ...
