For the analysis of geospatial data, the statistical spatio-temporal aggregation (SSTA) is a frequently used functionality. Possible applications include infor- mation extraction (Andrienko & Andrienko 2006), data fusion (Wiemann & Ber- nard 2010), generalization and schema transformation (Foerster et al. 2010). On the basis of spatial and temporal references, SSTA transfers thematic attribute values into a coarser spatio-temporal resolution using descriptive statistical op- erations. Reusable processing functions are increasingly offered in Spatial Data Infra- structures (SDI) through standardized interfaces using...

The contribution presents the development and application of a script for bulk assessment and interpolation of data in R scripting language.
Geospatial modelling revolves around the structures of data and the semantics of these structures. This is enough in simple cases, but becomes insufficient when the best structure and semantics is hard to find or the solution is too heterogeneous to fix and reuse. Field-based and objects-based geospatial models often share com- mon GIS data structures interchangeably, but their all possible meanings are too many to define in an immutable manner. Less studied approach to geospatial mod- eling is using mutable...

This deegree service implements the OGC WMTS 1.0.0 specification and is going to be the OGC reference implementation for this specification. Both, the OGC WMTS test suite and deegree's candidate reference implementation have been developed within the OGC OWS-9 initiative.
Extremely fast, free and open-source OGC WMTS server for pre-rendered tiles running on any web server
This paper presents a novel open source toolbox for street network comparison based on the Sextante geoprocessing framework for the open source Geographic Information System Quantum GIS (QGIS). In the spirit of open science, the tool- box enables researchers worldwide to assess the quality of street networks such as OpenStreetMap (OSM) by calculating key performance indicators commonly used in street network comparison studies. Additionally, we suggest two new perfor- mance indicators for turn restriction and one-way street comparisons specifically aimed...
EarthServer introduces distributed real-time analytics on Big Earth Data
This presentation will describe the way to make a geoportal used and useful.
CKAN is the most widely used open source data portal software across the world, built on open standards to make data easily discoverable and reusable. This presentation will explore what features allow publishing geospatial metadata with CKAN, providing an alternative to traditional geospatial catalogs, and more particularly how it has been used to build the new version of geo.data.gov, the US Government official online data catalog.
An open source solution to flight planning for pilots.
The importance of understanding the quality of data used in any GIS operation has increased significantly as a result of the advent of Free and Open Source (FOSS) tools and Open Data, which in turn have encouraged non-specialists to make use of GIS. Metadata (data about data) traditionally provides a description of this quality information and permits data curation, but it is frequently deemed as complex to create and maintain. Additionally, it is generally stored separately from the data, leading...
Challenges and successes in implementing real-time, browser-based social media analysis & visualisation with open-source tools.
OSGeo Live provides a valuable "system in a box" for MSc teaching in GIS, particularly for creating & managing GIS web services
In this presentation I demonstrate the use of Spatial OLAP for better Asset Management of Provincial Waterways.
Visualization of large spatial data is a complex process and many GIS packages use their own assumptions or special storage formats to render quality data. Im- age pyramids and tile based rendering are used for raster data visualization but vector dataset uses feature limiting mechanism for progressive rendering. For vec- tor dataset these methods improve rendering but have very little visual appeal and make visual interpretation difficult. This paper proposes a method for rendering Vector data, called Vector Pyramids, that...
India’s coastline is under tremendous pressure. The current processes of development are becoming a threat to the ecology and livelihoods housed on the coast. If left unchecked, there will not be much of a coast left for our future generations. GIS provides tremendous opportunities to map spatial information for better decision making. Government agencies generate maps, but they are localized and inaccessible, preventing an actual assessment of the damage that is already happening to our coast. The Coastal Area Mapping...

CLEANWATER system combine various information in order to evaluate the present level of nutrient pollution in vulnerable areas and to assess the cost-efficiency of the measures that could be applied. Through a simple and intuitive web interface, CLEANWATER offers the decision makers a spatial aware tool to (1) create scenarios related to the human activities and climate changes, (2) send those scenarios to numerical models to model future evolution of water quality and (3) view, query and perform spatial analysis of the simulation results. The system is build entirely with standard compliant free and open source software applications like OpenLayers, ExtJS, PostGIS, GeoServer and GDAL.
This presentation will show the current status of Open Source implementations of WCS and particularly EO-WCS by comparing GeoServer and MapServer/EOxServer
Using OS OpenData, applying OGC standards & services and customising a number of open source GIS tools a WebGIS App was developed to provide a simple and intuitive online tool for generating hydrological catchments within the UK .  http://webgis1.lutraconsulting.co.uk/catchment_finder/
Driven by the rise of Web 2.0 and the non-stop spread of mobile device sensors, the concept of PGIS (Participatory GIS) is knowing a new, revolutionary era. This research investigates the opportunity to build up a prototype of Participatory GIS, with completely FOSS architecture, in which data directly comes from field surveys carried out by users. As a result, the system should increase public active participation in data creation and sharing, besides enlarging the knowledge up to the local level....
Developed to address limitations of existing hydrological desktop applications, OASIS-WS utilises the latest advancement in web technologies & data availability to inform key decision makers of the impacts of land management on water resources & flood risk through a robust and consistent web-based approach.
This presentation will talk about the recent positive change of Korean government's policy toward open source GIS and its background rationale by reviewing past investment on Korean GIS from 1995 to 2011 and related research reports on open source GIS adoptions in Korea.
