Abstract Characterization of oil palm plantation is a crucial step toward many geographical based management strategies, ranging from determining regional planting and appropriate species to irrigation and logistics planning. Accurate and most updated plantation identification enables well informed and effective measures for such schemes. This paper proposes a computerized method for detecting oil-palm plantation from remotely sensed imagery. Unlike other existing approaches, where...

Abstract Digital watermarking is increasingly being used in the copyright authentication of vector maps to prevent misuse and illegal distribution. However, it is difficult to avoid influences on watermarks when undergoing spacial projection transformations, vector data compression, and other common geographic information system (GIS) operations. In this paper, a highly robust copyright-authentication method is proposed for digital vector maps. First, we discuss the descriptive...

Abstract Exploring hydrological and ecological processes plays a key role in understanding ecosystem developments. In this respect, the constructed catchment, Chicken Creek, has been established for fundamental and interdisciplinary scientific research. Since 2005, an ongoing monitoring program has been launched to measure hydrological, biological, meteorological, and pedological parameters during the ecological development of the site. This comprehensive and multidisciplinary...
