Recently, with InSAR data provided by the German TanDEM-X mission, a new global, high-resolution Digital Elevation Model (DEM) has been produced by the German Aerospace Center (DLR) with unprecedented...
GlobeLand30, the world’s first 30m-resolution global land cover data set, has recently been issued for research on global change at a fine resolution. Given the accuracy of GlobeLand30 data may show s...
Laser scanners are used more and more in mobile mapping systems. They provide 3D point clouds that are used for object reconstruction and registration of the system. For both of those applications, un...
It is inevitable to bring about uncertainty during the process of data acquisition. The traditional method to evaluate the geometric positioning accuracy is usually by the statistical method and repre...
Since the launch of high-resolution sensors, the use of satellite images as a major source of spatial information has been the subject of extensive research in a broad range of applications. In partic...
Thematic mapping is one of the major application fields of remote sensing techniques. Data quality of the thematic data was concerned about. At present, there are a lot of researches that focus on the...
We present in this paper an algorithm for the detection of changes based on terrestrial laser scanning data. Detection of changes has been a subject for research for many years, seeing applications s...
Countryside agencies in the UK are interested in how to generate a range of Boolean maps whilst controlling uncertainties in ways that are appropriate to different landscape questions. This work illus...
In analogy to spatial and temporal reference systems, semantic reference systems have been proposed to support interoperation between information communities. Such reference systems provide the struct...
Gis and uncertainty management     Spatial information sciences  GIS  contextual modelling       font style='font-size:12px;'> 2015/8/21
The contribution deals with issues that are very closely connected: Web services model, Dynamic GIS and the problem of uncertainty of spatial data and discusses the possibilities of the context use a...
This contribution concentrates on the determination of thematic uncertainty after the classification process. It is shown that in this context – in particular when evaluating remotely sensed scenes sh...
Hydrological and erosion studies in Way Besai watershed in Sumberjaya, West-Lampung, Sumatera, Indonesia, require assessment of slope and flow pathways. A Digital Elevation Model (DEM) was generated ...
Although uncertainties exist in spatial knowledge discovery, they have not been paid much attention to. In the past years, the most researches of spatial knowledge discovery focused on the methods of ...
