Managing Uncertainty in the Detection of Changes from Terrestrial Laser Scanning Data
Terrestrial laser scanning Change detection Point clouds
2015/12/16
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...

This paper takes the cloud model into land price information inquiry, using cloud model to express the spatial concept and the attributes of spatial entity described with qualitative language, it inte...
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 ...
UNCERTAINTY,VAGUENESS AND INDISCERNIBILITY:THE IMPACT OF SPATIAL SCALE IN RELATION TO THE LANDSCAPE ELEMENTS
uncertainty scale grain habitats
2015/9/28
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...
OVERALL UNCERTAINTY OF GEOREFERENCING AND CLASSIFICATION
