A Generic Web Service for ad-hoc Statistical Spatio-Temporal Aggregation
Mario Hartwig, Matthias Müller : Analysis SDI Standards Academic Track
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...

Bytecode unification of geospatial computable models
Jan Kolar : Standards Analysis Academic Track
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...

Evaluating open source GIS techniques for addressing database, analysis and visualization aspects of spatiotemporal information
Lynnae Sutton : Fish Passage Center (with Jackie Olsen (2nd author)) Development JavaScript OpenLayers Qgis Under the Hood
Most GIS were not specifically designed to manage dynamic spatiotemporal data. Spatiotemporal mapping is the representation of changes in geographical phenomena over time. By identifying the characteristics of the spatial, temporal and attributional dimensions, we evaluate, compare and contrast OSGIS techniques for data storage, retrieval, pattern analysis and visualization of spatiotemporal data. Some of the open source software evaluated includes: Weave, timemap.js, Dojo.js, QGIS temporal extension, OpenLayers Tracking, D3 and i2maps.

This modelisation allows to encapsulate all machine learning algorithms from OpenCV in addition to libSVM. A factory pattern allows to save trained algorithms parameters and automatically load the file into the appropriate algorithm. This extends greatly the set of available algorithms and allows for joint training of multiple algorithms for instance.

Semantically Enriching an Open Source SOS Implementation for Accessing Heterogeneous Environmental Data Sources
Desiree Hilbring, Anastasia Moumtzidou, Jürgen Mossgraber, Stefanos Vrochidis : Sensor Web Standards Portal Academic Track
Many kinds of environmental data are nowadays publicly available, but spread over the web. This paper discusses using the Sensor Observation Service (SOS) standard of the Open Geospatial Consortium (OGC) as a common interface for providing data from heterogeneous sources which can be integrated to a user tailored environmental information system. In order to allow for providing user-tailored and problem-specific information the adjusted SOS is augmented by a semantic layer which maps the environmental information to ontology concepts. The necessary...

Taarifa: Improving Public Service Provision in the Developing World Through a Crowd-sourced Location Based Reporting Application
Mark Iliffe, Giuseppe Sollazzo, Jeremy Morley, Robert Houghton : Humanitarian Project Mobile Academic Track
Public service provision in the developing world is challenged by a lack of coherence and consistency in the amount of resources local authorities have in their endowment. Especially where non-planned urban settlements (e.g. slums) are present, the frequent and constant change of the urban environ- ment poses big challenges to the effective delivery of services. In this paper we report on our experiences with Taarifa: a location-based application built through community development that allows community reporting and man- aging of local issues.

Taming rich GML with stETL, a lightweight Python-framework for geospatial ETL
Just van den Broecke : Just Objects B.V. Catalog PostGIS Project Showcase
stETL, Streaming ETL and pronounced "Stetl", is a lightweight, geospatial ETL-framework written in Python, that tightly integrates and combines existing transformation tools like GDAL/OGR, XSLT and PostGIS. stETL targets ETL-cases that involve complex XML and GML data, like INSPIRE Data Harmonization but any other transformation, even non-geospatial, can be applied as well. stETL applies declarative programming: a configuration file specifies an ETL chain of input/filter/output modules. Standard modules are available or can be user-defined. stETL is speed-optimized, by using native calls to for example GDAL/OGR, libxml and libxslt.

Using Free and Open Source GIS to Automatically Create Standards-Based Spatial Metadata in Academia - First Investigations
Claire Ellul, Nart Tamash, Feng Xian, John Stuiver, Patrick Rickles : Catalog Portal Standards Academic Track
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...

Vector Pyramids: A Multi-scale vector rendering and processing algorithm
Mohammed Rashad, Krishnan Rajan : Visualisation Under the Hood Big Data Academic Track
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...
Virtual Coast Guard - An Open and Crowdsourced GIS Portal for Stewardship of India’s Coast
Alpesh Gajbe, Adya Shankar, Sudarshan Rodriguez : Project Portal Academic Track
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...
