Ontology-driven map generalization
Different users of geospatial information have different requirements of that information. Matching information to users’ requirements demands an understanding of the ontological aspects of geospatial data. In this paper, we present an ontology-driven map generalization algorithm, called DMin, that can be tailored to particular users and users’ tasks. The level of detail in a generated map is a...
متن کاملMap Generalization by Skeleton Retraction
Much work has been done in the last few years on various aspects of automated map generalization. However, many of these efforts have been directed to the generalization of individual objects houses, roads, etc. while ignoring the spatial relationships between the objects themselves. This problem is particularly apparent where map generalization includes the simplification of contour lines (whi...
متن کاملOntology-aided annotation, visualization, and generalization of geological time-scale information from online geological map services
Geological maps are increasingly published and shared online, whereas tools and services supporting information retrieval and knowledge discovery are underdeveloped. In this study, we developed an ontology of geological time scale by using a RDF (Resource Description Framework) model to represent the ordinal hierarchical structure of the geological time scale and to encode collected annotations...
متن کاملMap Generalization of Road Networks
The present paper introduces a new algorithm for the elimination of arcs in road maps. The algorithm is based on information theory. A case study illustrates how the algorithm works. The perceptual properties of the map reader and the resolution of the display unit are brought into the algorithm by a similarity function.
متن کاملResearch on Spatial Data Line Generalization Algorithm in Map Generalization
Map Generalization is one of the hotspot issues in GIS. It is the most imperative field for intelligence in GIS. The uncertainty and data quality of map generalization should be attached importance to in map generalization. The conventional methods of process of line generalization in map generalization are be introduced in this paper, and analysis decline in the quality of integrated because o...
