Data uncertainty in a hybrid GIS
Data Uncertainty Data Quality Hybrid GIS Raster-Vector-Conversion Polygon Overlay
2016/5/20
The paper presents a new approach for integrating data uncertainty into a hybrid GIS environment. Such a hybrid system can process raster data as well as vector data in an integrated manner taking unc...
UNCERTAINTY IN ENVIRONMENTAL DATA INTEGRATION INTO 3D URBAN INFORMATION SYSTEM
Environmental data urban data data integration uncertainty 3D GIS
2015/9/28
This paper introduces a 3D environmental urban information system which is to help urban designers and developers to analysing and evaluating the environmental impacts of their urban projects. Where u...
In flood modeling, awareness has grown that models may not be reliable and may be uncertain and that performances should be evaluated more critically. Models may be uncertain due to many reasons that ...

WebGIS River Sediments Basin Management Plans Environmental Communication Geospatial Data Uncertainty Quality Assessment
2015/9/21
This paper describes a WebGIS prototype developed for the Walloon administration to improve the communication and the management of sediments dredging actions carried out in rivers and lakes. In Wallo...
The fuzziness-based uncertainty of GIS products is studied from objective and subjective aspects respectively in this paper. From the
point of view of objective aspect, the fuzziness-based uncertaint...
Introducing an Accuracy Indicator Based on Uncertainty Related Measures
Analysis Accuracy Classification
2015/7/9
Traditionally accuracy assessment of the classification results uses some collected reference data (ground truth). Ground truth
collection is a time-consuming and money-swallowing activity and usuall...
