Geometry Updating for Geospatial Data Integration
Lots of geospatial data has been collected within the last decades due to advances in digital spatial data capturing technologies and this has brought in different versions of the same data sets. Although various spatial and mapping organizations are updating and revising geospatial databases with new data/information about our rapidly changing environment; there are challenges of how to effect...
متن کاملGeospatial Data Sharing Based on Geospatial Semantic Web Technologies
Geospatial data sharing is a concern in geospatial science because of the heterogeneity of existing geographical information systems. This study aims to examine the use of Geospatial Semantic Web technologies such as ontology, web services and the service-oriented architecture for enabling disparate heterogeneous legacy GIS to share and integrate information in a cost effective way to reduce sp...
متن کاملActive on-demand service method based on event-driven architecture for geospatial data retrieval
Timely on-demand access to geospatial data is necessary for environmental observation and disaster response. However, traditional service methods for acquiring geospatial data are inefficient and cumbersome, which is not beneficial for timely data acquisition. In these service methods, data are obtained and published by managers and are then left to users to discover and to retrieve them. To so...
متن کاملEvent-based Incremental Updating of Cadastral Database
Incremental updating of cadastral database means that master spatial data set is updated when any change (geometric or semantic) occurs, the change can be recorded, updated and provided successively to users. During this process, a set of editing operations is needed to add, delete or amend cadastral spatial objects (intermediate points, boundary points, boundary segment, and parcels). An event...
متن کاملEvent-Driven Ontology Updating
Ontologies, as reliable resources in decision making processes, need to be accurate and up-to-date. For this purpose, ontologies have to be maintained regularly. Manual updating is tedious and time consuming, therefore we propose an event-driven automated ontology updating approach. The Ontology Update Language (OUL) and our proposed extensions are inspired by the existing SQL-triggers mechanis...
