Geo-Data Policy in Austria
"... Since several years efforts have been made in Austria to develop the E-Government and establish policies for the han-dling of public sector spatial data. Whereas the activities towards E-Government services were straightforward and mainly focused on technical issues, the geo-data policy developments ..."

Automating the Semantic Annotation of Geodata
"... Abstract. The ability to represent geospatial semantics is of great importance when building geospatial applications for the web. It will not only enhance discovery and retrieval of geographic information, but it will also enable its translation and reuse in contexts other than the original one. We ..."

propose a method for automating the semantic annotation of geodata based on spatial characteristics and suggest applying spatial analysis methods for extracting information useful for the annotation process. The approach is illustrated by a case study on annotating data sources containing representations
A Framework for Visualizing Multivariate Geodata
"... Abstract: In urban planning, sophisticated simulation models are key tools to estimate future population growth for measuring the impact of planning decisions on urban de-velopments and the environment. Simulated population projections usually result in bulky, large-scale, multivariate geospatial da ..."

data sets. Millions of records have to be processed, stored, and visualized to help planners explore and analyze complex popu-lation patterns. This paper introduces a database driven framework for visualizing geospatial multi-variate simulation data from UrbanSim, a software-based simulation model
The role of spatial relations in automating the semantic annotation of geodata
- In COSIT
, 2005
"... Abstract. How can the usability of distributed and heterogeneous geographic data sets be enhanced? Semantic interoperability is a prerequisite for effectively finding and accessing relevant data in different application contexts. By using geospatial domain ontologies and semantic annotations of geod ..."

of geodata based on these ontologies semantic interoperability can be achieved. However, since no automated methods for the semantic annotation of geodata exist this remains a laborious task, which data providers are neither willing nor capable to perform. In this paper we propose a method for automating
GeoTest: A Testing Environment for Swedish Geodata
"... GeoTest is a project initiated by Future Position X (a GIS cluster organization in Gävle, Sweden), the National Land Survey of Sweden (NLS) and the University of Gävle. The project aims to test Swedish geodata and make sure they comply with the INSPIRE specifications in Annex I–III. The purpose of t ..."

Constructing Gazetteers from Volunteered Big Geo-Data Based On Hadoop
, 2014
"... Traditional gazetteers are built and maintained by authoritative mapping agencies. In the age of Big Data, it is possible to construct gazetteers in a data-driven approach by mining rich volunteered geographic information (VGI) from the Web. In this research, we build a scalable distributed platfor ..."
