Photogrammetric systems are important sources for GIS databases. Currently, the trend towards the integration of photogrammetric systems and spatial databases is increased significantly. Integration o...
Generic Framework and Key Issues for Updates Propagation between Heterogeneous Spatial Databases
GIS Database Updates Propagation Schema Matching Updates Retrieval Semantic Transformation Update Integration Consistency Maintenance
2015/10/12
Data updating is a significant stage in the life of a geographical information system (GIS). When geodata producers have finished
updating their own database (named Master Database, MDB), the proble...
Data Harmonisation and Optimisation for Development of Multi-scale Vector Databases
Multi-source multi-resolution vector database data Kits imagery requirements and constraints
2015/10/12
The increasing number of Earth observation sensors on the market is making the choice of optimized data sources to serve
operational needs more complex than ever before. Applying a geographic perspe...

An algorithm for building detection in aerial images is presented. The algorithm is based on a combination of unsupervised segmentation and selection of a training set based on existing building regis...
INTEGRATING EARTH OBSERVATIONS DATA INTO GEOSPATIAL DATABASES THAT SUPPORT PUBLIC HEALTH DECISIONS
Earth observation System integration Internet GIS
2015/8/31
There are several reasons why public health communities do not use information from Earth observations routinely. Most notable
among them are: (1) they need science results that verify, validate, and...
Modern geographical information systems make it possible to integrate information from multiple sources in different forms for
querying and analysing information. So the importance of geospatial data...
In this paper an approach to the automatic quality assessment of existing geo-spatial data is presented. The necessary reference
information is derived automatically from up-to-date digital remotely ...
