One of the main challenges in spatial data mining is to automate the data preparation tasks, which consume more than 60% of the effort and time required for knowledge discovery in geographic databases. In this paper we present an extension of the classical open source data mining toolkit WEKA ...
Spatial data isany data with a location component. Databases with geographic references, suchas addresses, phone numbers and postal codes may now analyse this informationusing third party geocoding tools and services. The Oracle Spatial geocodingfeature matches these records with a latitude/longitude poi...
Data management is important because organizations are working with more geographic information system (GIS) data than ever before and need safe and efficient ways to gather, organize, and secure it. In today's digital economy, data is an asset that can be used to make better-informed decisions...
Database (dataset) composition The Database consists of a system library, character library, and attribute library; sub-databases related to tectonic facies zoning, magmatic rock belts, geographic base map and ore occurrences; six thematic map layers of the intrusives of the Precambrian, early Pale...
Knowledge discovery is a user-dependent process, but the user is usually neither an expert in geographic databases nor in spatial relationships. This paper presents an approach to reduce the number of spatial relationships for knowledge discovery, using a geo-ontology and semantic spatial integrity ...
Based on this model, a star schema SDW (Spatial Data Warehouse) is designed and a SOLAP (Spatial OLAP) is implemented to aid in making optimal decisions regarding geospatial database updating. 展开 关键词: geospatial data update GIS (geographic information system) SDW (spatial data warehouse) ...
