    Analysis of GIS data to investigate natural resource impacts of high-voltage overhead lines in the examples in Lower Saxony and North Rhine-Westphalia
    (Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Thinh, Nguyen Xuan; Sander, Leon; Kopec, Jakob; Mühlnickel, Kai
    In this paper we describe shortly Lower Saxony and North Rhine-Westphalia as study areas and the legal framework, both in the context of natural resource impacts of high-voltage overhead lines. We then conduct the buffer analysis of a GIS dataset in order to investigate natural resource impacts of existing high-voltage overhead lines in the two mentioned study areas. The paper is based upon the first results of the interdisciplinary research and development project "Power Network Planning" funded as part of the 6th Energy research program "Research for an environmentally friendly, reliable and affordable energy supply" by the German Federal Ministry of Economics and Technology (BMWi).

    Investigation of Land Cover Change and Land Surface Temperature for the Megacity Ho Chi Minh City using Landsat Imagery
    (Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Thinh, Nguyen Xuan; Kopec, Jakob
    Rapid uncontrolled urban growth over last twenty years creates significant pressures for the environment and many challenges for urban planning in Ho Chi Minh City (HCMC). One of the big challenges is land management. The application of remote sensing can provide reliable and current geodata bases for land management and land use monitoring in HCMC. In this study we used Landsat Imagery to detect and analyse the land cover change HCMC for the periods 1989 2000, 2000 2002 and 2002 2005 in order to find out the extent of the urban growth in HCMC in these time periods. The next important task is to evaluate the urban growth regarding well known urban planning principles like the compact city or the city of short distances . This will be done by mean of urban density gradient , the jaggedness degree and the centre oriented entropy developed by Thinh (2004). Our results show the dimension of urban expansion in HCMC and the potential of the linkage between remote sensing techniques and urban form metrics as a powerful and useful tool for modern land use change monitoring. They are very useful for the investigation of growth patterns and land use planning in HCMC.
