Research on GIS applications in the real world context has to be strengthened besides developing GIS application software itself. An ecologically important field of applications is the integration of ...
Triangulated Irregular Network (TIN) is a high-effect means expressing the terrain surface in the computer, compared with GRID model, TIN model can use less sampling to approach the terrain surface pr...
MODELLING QUALITATIVE AND QUANTITATIVE UNCERTAINTIES OF OBJECTS EXTRACTED FROM HIGHRESOLUTION MULTI-SPECTRAL IMAGES AND LASER SCANNING DATA

2015/6/1
Local coordinates based on the Voronoi diagram are used in natural neighbour interpolation to quantify the “neighbourliness” of
data sites. In an earlier paper, we have extended the natural neighbour...
PARALLEL PROJECTION MODELLING FOR LINEAR ARRAY SCANNER SCENES

2015/6/1
Digital frame cameras with resolution and ground coverage comparable to those associated with analogue aerial cameras are not yet
available. Therefore, linear array scanners have been introduced on ...
