Article
Full-text available
Studying the relationship between river water and shallow groundwater (SGW) during flood events is a research topic receiving increasing attention for many reasons. This phenomenon was studied with respect to Mohács Island of the Danube (Hungary) in an area protected by a levee. Floods only infiltrate into the island through the aquifer, where prod...
Article
Recent trends show that developers behind some of the most popular web mapping libraries put excessive work into creating custom hardware-accelerated rendering engines. Other libraries focus on functionality rather than visualization. From the perspective of the developer using these libraries an important question arises: is it necessary to use a...
Article
Full-text available
Companies and individual developers have recently put serious effort into improving web mapping libraries. A significant front in this development is hardware‐accelerated vector graphics. Owing to those efforts, and the continuously evolving World Wide Web, users can visualize large vector layers, and even animate them. On the other hand, this rapi...
Conference Paper
Full-text available
This paper presents a Web-based implementation of the coverage model, which was proposed to extend the traditional raster model. While the coverage model is able to overcome the most severe disadvantages of the raster model (e.g. reprojection, sampling bias), its vector-based display model needs more computational power. In order to create a proof...
Conference Paper
Full-text available
In this paper we present an alternative, vector based coverage model, which could extend the traditional raster model. As the coverage model only changes the representation model behind rasters, it needs minimal effort to implement, mitigates current raster limitations, and has minimal performance impact due to modern comput-ers' increased computin...

Full-text available
The increasing capabilities of web browsers and the growing spread of JavaScript have an impact on the development of web-based GIS systems. While in traditional Web GIS applications the client-side component is only responsible for creating representation models, modern geographically enabled JavaScript libraries have extended capabilities, making...

Az első multispektrális adatok megjelenése óta foglalkoztatja a kutatókat az ilyen adatok kiértékelése különböző módszerekkel. Igazán elterjedt módszer az automatikus, vagy felügyelt klasszifikáció, mely során különböző spektrális tartományokban készült képekből dimenziócsökkentő eljárásokkal osztályozott állományok készülnek. Egyik fontos célja a...
