INTERSECTION DETECTION BASED ON QUALITATIVE SPATIAL REASONING ON STOPPING POINT CLUSTERS
clustering spatial reasoning relational reasoning
2016/7/8
The purpose of this research is to propose and test a method for detecting intersections by analysing collectively acquired trajectories of moving vehicles. Instead of solely relying on the geometric ...
Analysis of the addition of qualitative ancillary data on parcel-based image classification
Database updating object-oriented classification trees high resolution imagery
2016/1/25
Parcel-based classification of high-resolution images is one of the most reliable alternatives for the automatic updating of land
cover/land use geospatial databases. Each parcel can be characterize...
Qualitative Detailed Description for Spatial Direction Relations
Spatial Information Sciences GIS Analysis Model Reasoning Spatial Direction Relations
2015/12/2
Direction relation is an important spatial relation. Descriptions and representations for direction relations have different levels of detail because of different dimensions of spatial objects and dif...
QUALITATIVE AND QUANTITATIVE ASSESSMENT OF HIGH RESOLUTION MULTISPECTRAL IMAGE USING FUSION TECHNIQUE BY MEASURING ENTROPY– A CASE STUDY USING QUICKBIRD DATASET
Information Fusion Entropy
2015/8/31
This paper presents the qualitative as well as quantitative assessment of high resolution image generated by fusion technique. The
information contained in fused image measured and compared with diff...
QUALITATIVE SPATIAL REASONING ABOUT INTERNAL CARDINAL DIRECTION RELATIONS
Qualitative Spatial Reasoning Internal Cardinal Direction Relation External Cardinal Direction Relation Distance Relation Topological Relation Composition Table
2015/8/10
A class of novel spatial relation, internal cardinal direction (ICD) relation, is introduced and discussed. Applying ICD-9 model, the characteristics and the simplification rule of ICD relations are d...
AN INTEGRATED MODEL FOR FUZZY TOPOLOGY AND QUALITATIVE DISTANCE FOR DISCRETE SPACE
topologic relation model discrete space fuzzy region
2015/8/10
The topological relationship of disjoint is ubiquitous in physical world, while the traditional topological relationship models do not take more considerations about it. Point set topology is exhausti...
MODELLING QUALITATIVE AND QUANTITATIVE UNCERTAINTIES OF OBJECTS EXTRACTED FROM HIGHRESOLUTION MULTI-SPECTRAL IMAGES AND LASER SCANNING DATA
Quality Uncertainty Object Extraction
2015/6/1
An object-based approach is applied in land-cover feature extraction from high-resolution multi-spectral images and laser scanning
data in this research. Objects extracted from high-resolution spect...

Quantitative versus Qualitative Geospatial Data in Spatial Modelling and Decision Making
Quantitative and Qualitative Geospatial Data Spatial Modelling and Decision Making
2012/6/8
In general, geospatial data can be divided into two formats, raster and vector formats. A raster consists of a matrix of cells where each cell contains a value representing quantitative information, s...
