The high resolution and span diversity of colored Google Earth images are the main reasons for developing a vegetation extraction mechanism based on BPNN (Back Propagation Neural Networks) that can work efficiently with poor color images. This paper introduces a method based on neural networks that can efficiently recognize vegetation and discriminate its zone from the desert, urban, and roadst...

Visibility analysis or Viewshed is a common function of almost all GIS systems. The aim of this project is to find out the best solution, to compute viewshed for the Olomouc region and ensure the best way of visualisation of the results. The first step to analyze the visibility is making a high quality Digital Terrain Model, choice of the best interpolation method and subsequent addition of veg...

With Google Earth being widely used by the general public and professionals, Virtual Globes are revolutionizing the way in which scientists conduct their research and the general public uses geospatial-related data and information. NASA Goddard Earth Science Data and Information Service Center (GES DISC) developed a service-oriented online scientific data analysis system to provide customable o...

We developed a software tool for runners and other sportsmen that is capable of visualizing recorded Global Position System (GPS) data of sports activity. If available, heart rate (HR) as well as other meta data can be visualized along with the position. The goal of the work was to create public domain software under the general public license (GPL) for post-training-analysis of running session...

Geographic Information Systems (GIS) handle a wide range of problems that involve spatial distribution data from fields as diverse as housing, healthcare, transportation, cartography, criminology, and many others. Selecting the right GIS is determined by the task the user wishes to perform. Some considerations may include the availability of analytical functions, performance, ease of use, inter...

This paper covers the use of depth sensors such as Microsoft Kinect and ASUS Xtion to provide a natural user interface (NUI) for controlling 3-D (three-dimensional) virtual globes such as Google Earth (including its Street View mode), Bing Maps 3D, and NASA World Wind. The paper introduces the Microsoft Kinect device, briefly describing how it works (the underlying technology by PrimeSense), as...

Background Advances in the field of virtual microscopy are continuously growing. Many companies have introduced equipments with very good image quality levels, and increased speed in the scanning processes. However also a wide variety of image formats, software viewers and servers have appeared, with lack of compatibility in the managements of virtual slides. Commercial solutions for virtual mi...
