“…In the present study, the elevation data was based on the EU-DEM database available as a free download from the European Environment Agency (EEA) website. This was created using the latest versions of the ASTER-GDEM and SRTM (Shuttle Radar Topography Mission) surface models (Hensley et al, 2000;Hennig et al, 2001;Farr et al, 2007) with additional edits to improve the water surfaces. The final model is a 30-metre-resolution, medium scale raster surface, which is very usable for researches based on water-shed basins (Tøttrup, 2014).…”

Simulating Environmental Impacts Based On The Example Of Roşia Montană

One of the challenges of modern terrain modelling methods is to incorporate non-existing, planned features in the output. Remote sensing based solutions can only detect structures and shapes that are already present in the environment. In order to assess the impacts of a planned development on the surrounding landscape properly it is inevitable to solve this issue. In addition to the environmental, social and economic consequences, mining activities, especially open cast mining will also leave significant scars on the landscape. These can not only have a visual effect but also impact local weather conditions by changing winds, precipitation patterns. The current paper demonstrates a collection of methods and techniques able to cope with the various challenges that arise when modelling the landscape impacts of such developments. The experiments were performed in the area of Roşia Montană, where a Canadian company plans to create the largest open cast gold mine in Europe. The results of the terrain modelling process allow for the quantification of the estimated impacts on the terrain and the land cover of the area caused by the mining project. The presented methodology and visualisation tools can also facilitate the decision support mechanisms making the communication 'more understandable' amongst stakeholders; information meetings and public hearings involving organizing groups at any level. Obtaining the results required the development of several unconventional techniques especially in terrain modelling and visual landscape simulation, involving the combination of sometimes very different base methods.

“…To prepare a SRTM-based (Shuttle Radar Topography Mission) Pan-European river-and water catchment database, with basic resolution of 100 metres, an adaptive process was used, based on relief model analysis (Hensley et al, 2000;Hennig et al, 2001;Rodriguez et al, 2005Rodriguez et al, , 2006Vogt et al, 2007;Reuter et al, 2007a, b;).…”

In term of floods the current area of Hungary has extensively been endangered. Modelling of flood processes -mainly following the hydrological events in the riverbed -has recently been developed. As far as protection dykes provide protection of the inhabited and agricultural areas, the flood models can run with acceptable preciseness. However, when dykes cannot withstand against the increasing load and a dyke burst occurs, fast and efficient protection measures shall be taken in the protected areas.The dynamic 4D Flood model presented in this paper makes possible a fast modelling of dyke burst occurring in the protected side and spreading of water mass, based on real parameters. For this reason the features of protected area shall be recognised, for example topology of creeks, features of agricultural and inhabited areas, parameters of roads, railways, rainwater drainage, buildings, natural conditions (soil parameters, meteorological characteristics, etc.). The results satisfy the comprehensive demands of the Directorate General for Disaster Prevention of Borsod-Abaúj-Zemplén County. In case of dyke burst, the completed Flood Model can run the expected events of the next hour in a few minutes. This time is enough for the specialists to bring operative decisions to protect the inhabitants and avoid material losses.

The three-dimensional imaging microware altimeter is a new type of altimeter, which combines with traditional altimeter height tracking measurement technology, SAR synthetic aperture technology and SAR interference measurement technology. The direct geolocation technology is a little different from traditional SAR geolocation technology. In this paper, a geometric positioning algorithm based on the RangeDoppler equations has been proposed for the three-dimensional imaging microware altimeter, and the main positioning error sources, including elevation error and atmosphere transmission delay, are analyzed and corrected. The positioning precision is validated by corner reflectors. The result shows that the direct positioning accuracy improved by 3 pixels.
