Successful PhD defense of Pablo Cabrera-Barona within the Doctoral College "GIScience"

Pablo Cabrera-Barona, PhD researcher at Z_GIS successfully defended his PhD Thesis “A Multidisciplinary Spatial Framework for Health Inequalities Analysis with Emphasis on Deprivation and Healthcare Accessibility”.

In his research, Pablo focused on the analysis of deprivation and healthcare accessibility, understanding them as integral concepts that incorporate objective and subjective measures, the integration of which enables the representation of multidimensional health-related phenomena. Pablo provided a multidisciplinary spatial framework that uses different mixed-methods approaches to understand health inequalities.

The results showed that the created deprivation indices facilitate the identification of social disadvantages and can support the explanation of health outcomes. It was also shown that the combination of objective measures and perceptions can represent inequalities of multidimensional healthcare accessibility and healthcare satisfaction and that these multidimensional measures can be explained by social factors of human health-related behavior. It could also be demonstrated that area-level features of deprivation and spatial accessibility to healthcare influence individual-level healthcare satisfaction.

Around 30 attendees from 14 different nations listened to Pablo’s impressive presentation which was followed by a fruitful discussion between the evaluators, Dr. Alexis Comber from the University of Leeds and Dr. Stefan Lang from Z_GIS. Dr. Thomas Blaschke as the main supervisor acted as the chair.

We wish Pablo all the best for his future endeavors and career!

MAPATHON goes AGIT / GI-Forum

Z_GIS lädt gemeinsam mit Ärzte ohne Grenzen (MSF) und dem Österreichischen Roten Kreuz  zu einem Mapathon in Salzburg ein.

Mapathons sind eingebettet in das Missing Maps Projekt von MSF, dem Roten Kreuz und dem Humanitären Open Street Map Team (HOT OSM) und bieten engagierten Freiwilligen überall auf der Welt eine Plattform, humanitäre Hilfe mit online mapping in Krisenregionen zu unterstützen. Geografische Details, wie Dörfer, Straßen und Infrastruktur werden basierend auf Satellitenbildaufnahmen interpretiert und kartiert, und bieten somit für die Arbeit von Hilfsorganisationen eine wichtige Informationsgrundlage, damit diese im Krisenfall schneller und gezielter reagieren können. Bei diesem Mapathon, der zum ersten Mal im Rahmen der AGIT in Salzburg stattfindet, wird ein Gebiet bearbeitet, das aktuell von Naturkatastrophen, Krankheiten oder Konflikten betroffen ist und in dem sowohl MSF wie auch das Österreichische Rote Kreuz aktive Hilfe leisten.

Wer kann mitmachen?
Jede/r kann mitmachen, egal ob Anfänger/in oder erfahrene Mapper. Mitzubringen ist lediglich ein eigener Laptop (inkl. Maus).

Wann & wo findet der Mapathon statt?
Dienstag,  4. Juli 2017
17 bis 19 Uhr
im Rahmen der AGIT / GI-FORUM 

Achtung: für die Teilnahme am Mapathon muss keine Konferenzgebühr bezahlt werden! Es genügt eine Registrierung im AGIT Tagungsbüro.

Project X3D4Pop kicked off: Population estimation in urban areas from experimental 3D remote sensing data

How many people live in a city? This seemingly simple question very often arises in the daily work of MSF (Doctors without Borders) or SOS Children’s Villages. Activities like a vaccination campaign or the preparation for natural disasters require up-to-date population figures. With more and more people moving into cities, the sprawling urban areas move more and more into the focus of aid and relief organisations.

Population numbers can be estimated from the number of buildings mapped in remote sensing data, but in urban areas, 3D data is required to account for the building heights. The research project X3D4Pop, which was kicked off in Salzburg in May, aims at exploring the potential of 3D data derived from satellite image pairs initially not acquired for stereo data production, as dedicated stereo image pairs are often missing. Can image pairs from different satellites, acquired at different times, be used to derive building heights?

X3D4Pop brings together experts in photogrammetry from the German Aerospace Center DLR and dasymetric mapping from the Austrian Institute of Technology AIT and the Swiss UNEP/GRID-Geneva, and is led by Z_GIS to further enlarge the portfolio of remote sensing services for humanitarian organisations. X3D4Pop is funded by the Austrian FFG, the Swiss Space Office SSO, and the DLR.

New Z_GIS project MorphoSAT: Automated geomorphological mapping based on satellite data

The MorphoSAT project started at the beginning of May and is funded for a total lifetime of 24 months by the FFG within the ASAP 13 programme.
The main objective of the project team is to implement, test and validate an innovative system for operational production of objective GIS-ready, semantically-rich geomorphological maps/information. Therefore recent (near-)global consistent satellite data and products (WorldDEM, ERS-2/ENVISAT, Sentinel-2, Copernicus land services, etc.) as well as LiDAR data will be exploited and integrated. A maximized integration of experts and potential customers is envisaged in the specification and validation phases of the project.

Land@Slide team received valuable user feedback on web service

A user/validation workshop, organised by the Land@Slide project team, was successfully held at our department on May 24. The workshop aimed to bring together experts from regional and national authorities from Austria and Germany such as the Geological Survey of Austria (GBA), the Austrian Service for Torrent
and Avalanche Control (WLV) or the Bavarian Environment Agency (LfU). The experts require information on landslides for rapid mapping, documentation and monitoring purposes for managing related damages and risks.

A major objective of the workshop was to present, demonstrate and evaluate the pre-operational landslide platform and web mapping service which is developed within the Land@Slide project. The users had the opportunity to test the web service during interactive sessions. Their provided feedback on its functionality, usability and performance is of high value for improving the service. Participants also had a fruitful discussion on the potential of Earth Observation data and methods for landslide mapping. The workshop concluded with an investigation of the opportunities for developing the project outcome into an operational landslide web service.
