Open AccessBuilding pattern recognition in topographic data: examples on collinear and curvilinear alignments
Building patterns are important features that should be preserved in the map generalization process. However, the patterns are not explicitly accessible to automated systems. This paper proposes a framework an...

Spatial object aggregation based on data structure, local triangulation and hierarchical analyzing method
This paper focuses on the methods and process of spatial aggregation based on semantic and geometric characteristics of spatial objects and relations among the objects with the help of spatial data structure (...

Frameworks for generalization constraints and operations based on object-oriented data structure in database generalization
The constraints and the operations play an important role in database generalization. They guide and govern database generalization. The constraints are translation of the required conditions that should take ...

Diachronic Analysis of Fuzzy Objects
This paper presents a method to monitor the behavior of fuzzy spatial objects through time. The method consists of two steps. Firstly the spatial extents of objects are determined at several sequential epochs....

Ontology-Based Geographic Data Set Integration
In order to develop a system to propagate updates we investigate the semantic and spatial relationships between independently produced geographic data sets of the same region (data set integration). The goal o...

Identification of fuzzy objects from field observation data
This paper introduces the concept of fuzzy objects for modeling natural phenomena measured by field observation data. The propagation of uncertainties resulting from stochastic data errors and classification f...

Discrete spatial models for fuzzy geographical objects
The representation of objects and their relationships in a geo-information system will be in the form of data that should be structured according to some data base concept The map** of an original terrain de...

Topological querying of multiple map layers
This paper first recaptures why multiple map layers are required in Geographic Information Systems. The two main motivations are: flexibility in data modeling, and efficient processing of data. In order to mak...

Formal Data Structures and Query Spaces
Geo-information systems (GIS) are a special class of information systems, they handle data referring to objects and processes at the earth surface. Geometry is the important aspect of these data, setting GIS a...
