Heinz Faßmann, Federal Minister for Education, Science and Research visited the iDEAS:lab established by the Department of Geoinformatics – Z_GIS at the Science City Itzling. 

During his working visit to Salzburg, including meetings with the Governor of Salzburg and the Rectorate of the University of Salzburg, Minister Faßmann used the opportunity for a short visit bringing him back to his academic roots – the discipline of Geography. The 'virtual sandbox' is an attraction within the iDEAS:lab combining learning and fun. Changes in the sand surface are digitally scanned in real time and translated into a Digital Elevation Model. Elevation visualisations or analysis and modeling results, then are projected onto the sand, making this an  interactive 'playground'.

Z_GIS' iDEAS:lab has been opened in 2016, aiming at bridging education, research and the general public. Hundreds of pupils already had the opportunity to learn about geospatial technologies like remote sensing, interactive cartography, 3D printing and smart environments - sensor webs, applied across domains like community planning, humanitarian action, soft mobility and environmental issues.

Willi Mann successfully defended his PhD

Willi Mann successfully defended his PhD Thesis “Efficient Techniques for Set Similarity Join Queries”. While being a student at the Department of Computer Science Willi was associated with the Doctoral College “GIScience” at Z_GIS. 

The DK GIScience has profited from this in-depth research in database science. In particular the focus is to efficiently store and query very large volumes of data. The combination of database research and Geoinformatics will provide  a deeper understanding of fundamental problems in bridging the gap between database systems and GIS software.

In his Thesis, Willi focused on techniques for set similarity join queries. The join is a fundamental operation in databases. A growing number of problems require joins with fuzzy predicates. A class of frequently applied fuzzy predicates is the similarity of two sets. Typical set similarity functions include Jaccard, Cosine, dice, and Overlap, and the Hamming distance. The set similarity join can be executed in offline settings where the input is known up front and online settings, like on streams of timestamped sets. 

Willi’s work resulted in three high level publications which correspond to the three chapters of his thesis:  Willi proposed a new filter, PEL, for offline set similarity join algorithms. Then he extensively compared offline set similarity algorithms and finally he proposed a new algorithm, SWOOP, for set similarity joins on streamed data sources.

We wish Willi all the best for his future career and endeavours!

How to improve water management by using space technology

This issue was addressed by the 4th International Conference on the Use of Space Technology for Water Management, which recently took place in Islamabad, Pakistan. More than 100 experts from all over the world discussed cutting-edge tools and findings to better understand, describe and quantify water-related issues using space technology. The conference was organised by the the United Nations Office for Outer Space Affairs, the National Space Agency of Pakistan SUPARCO on behalf of the Government of Pakistan, and the Prince Sultan Bin Abdulaziz International Prize for Water.

The range of applications covered the entire water cycle - extending from precipitation estimation from satellite data to glacier mapping, run-off estimation, erosion and water quality assessment, evapotranspiration calculation and beyond.

In his keynote presentation within the session on case-studies, Lorenz Wendt (Z_GIS) gave insight into the lessons learned by Z_GIS from developing water-related information products and services and providing those to humanitarian actors within the EO4HumEn+ project.

The key to success in many water-related applications of space technology is the integration of remote sensing data with information collected in situ, by experts or measurement systems on the ground, which is both a technical and an organisational challenge. No the less, space technology bears a great potential to tackle the many water-related challenges the world is facing.

Stefan Zimmer - winner of 2018 EDC "Student of the Year" Award

As an ESRI Development Center, Z_GIS every year has the opportunity to nominate one top student based on his or her software development competence. This year this special honour is awarded to Stefan Zimmer for work leading to his University of Salzburg "Applied Geoinformatics" MSc Thesis "An Efficient Algorithm for Computing Space-Time-Linguistics - Similarities and Labelling Social Media Posts" supervised by Dr Bernd Resch.

Stefan Zimmer has recently completed his master's thesis at Z_GIS. Through his exceptional software development skills, he was able to develop and implement a number of geospatial applications using a variety of software technologies, including the extensive use of Esri technology for spatial data analysis and visualisation.

Spatial distribution of Boston tweets indicating
anger/disgust (red), fear (blue), and sadness (yellow)
In his thesis, Stefan developed a machine learning-based algorithm called TwEmLab (Twitter Emotion Labeller) that assigns emotion categories to social media posts like tweets. The workflow comprises a self-designed, multi-dimensional, similarity-based graph creation algorithm and the Junto engine that implements a graph-based labelling algorithm called Label Propagation. In addition to the methodological developments, he was able to convert the complex algorithm in a high-performance implementation that is able to process about 1,000 more datasets than comparable systems in a parallelised algorithm, both for CPU- and GPU-based operations:


Apart from that, Stefan developed a web-based real-time visualisation using Mapbox technology for physiological sensor data and social media posts for use in urban planning and management. Finally, in one of his course projects, he conceived and implemented a location-based game, in which a spaceship can be controlled using a mobile EEG device and voice commands - just using "the power of thought" without manual interaction. The application combines a variety of technologies using Unity, the Emotive SDK, Mapbox, Google Cloud Search API and Open Street Map.

Stefan Zimmer was a member of the successful team winning the first Copernicus Hackathon with the ‘ShareCropper’ concept >https://gi-science.blogspot.com/2016/11/zgis-team-won-first-open-data.html

Congratulations to this distinction, and to continuing a tradition of excellence established by previous recipients of this award like Azmat Arif in 2017!

Cornelia Schneider's successful PhD defense within the DK GIScience


Cornelia Schneider successfully defended her PhD Thesis “Methods for recording, processing and evaluating human movement data in the context of Active and Assisted Living”. While working for the “Salzburg Research” (SR), a research institution owned by the provincial Government of Salzburg, Cornelia has been associated PhD to the Doctoral College “GIScience”. At SR, she is the head of the competence field e-Health.

In her PhD, she contributed to tackle a major problem Europe aging Western societies are facing: The aging population will lead to a growing number of older people suffering from various ailments and consequently will be in need of support. Thus, the development of information and communication technologies (ICT) based assistance systems is of increasing importance. These so-called “Active and Assisted Living (AAL) solutions support older people to live independently as long as possible by maintaining and improving their quality of life.

In particular, the Thesis is based on research projects dealing with the development of a mobility assistance system and addressed research questions such as where patients typically stay, where they have been or where they most likely are going. This is answered by means of movement analysis together with complex spatio-temporal analyses. Next to technical and methodological issues of recording, processing and evaluating human movement data, usability of systems and how to deal with privacy concerns were major foci in this work which builds a significant contribution to the future development of mobility assistance systems.

We wish Cornelia all the best for her future endeavours!
