The SAFER Geodatabase for the Kathmandu Valley: Geotechnical and Geological Variability [PDF]
Earthquake Spectra, 2020 The Kathmandu Valley is within a seismically active region with only few recorded strong‐motion data. Geophysical information in the Valley is also sparse. In addition, the absence of an open database which compiles in situ geophysical tests, borehole records, and geotechnical laboratory data is affecting the advancement of ...

Leveraging Cloud Computing in Geodatabase Management
2010 IEEE International Conference on Granular Computing, 2010In this work, we leverage Cloud computing technologies in scaling out data management in geographical databases. In particular, we tackle the issue of data indexing in parallel. First, spatial data is partitioned and indexed in a Hadoop MapReduce cluster.

Improving Geodatabase Semantic Querying Exploiting Ontologies
2011Geospatial semantic querying to geographical databases has been recognized as an hot topic in GIS research. Most approaches propose to adopt an ontology as a knowledge representation structure on top of the database, representing the concepts the user can query. These concepts are typically directly mapped to database tables. In this paper we propose a

Pedestrian Navigation - Creating a tailored geodatabase for routing
2007 4th Workshop on Positioning, Navigation and Communication, 2007In this paper, we present an approach to generate a geodatabase accustomed to the specific needs of pedestrians for navigation applications. One of our goals is to use different existing geodatasets like topographic, cadastral and indoor vector map data and develop methods for deriving automatically an area-wide available geodata set adapted to the ...
