Z_GIS at International Cartography Conference, Chandigarh

The Department of Geoinformatics - Z_GIS was invited to contribute to the 41st INCA International Conference hosted by Panjab University, Chandigarh, India from October 27 to 29, 2021. 

Dr. Shahnawaz represented Z_GIS at this event and presented a plenary lecture on 'Remote Sensing Based Mapping and Monitoring of Atmospheric Pollution in India'. During the lecture, he showed spatial-temporal patterns of aerosols globally in general and in India specifically using TERRA-MODIS monthly datasets from 2001 to 2020. In addition, Dr. Shahnawaz also was honoured with chairing a technical session at this conference. 

Z_GIS will again be welcome at the 42nd INCA International Conference in Dehradun, India next year!

Soil Sealing Identification and Monitoring System – project kick off

On 24 September 2021, the SIMS (Soil Sealing Identification and Monitoring System) project held its kick-off meeting at the University of Salzburg with participants from the academic partner (University of Salzburg, Department of Geoinformatics - Z_GIS), industry partner, Spatial Services GmbH, and Austrian research promotion agency, FFG. The project is funded through the FFG’s Austrian Space Application Programme (ASAP) and runs until 2023.


The SIMS project builds upon the semantic EO data cube for Austria, called It aims to engage users in incorporating information derived from free and open Copernicus EO data towards a proof-of-concept implementation to detect and monitor soil sealing in Austria.

The project will implement a prototypical service in close collaboration with users from local and national authorities involved in regional planning and the environment.

 SIMS aims to:

  • Supplement very high resolution satellite images available to public authorities that are updated once every couple of years with dynamic information from Sentinel-2 images, which have alower spatial resolution, but much more frequent acquisitions every 3-5 days.
  • Detect and monitor sealed soils using prototypical reproducible and transferable ad-hoc semantic queries of enriched EO data. 
  •  Enable Austrian regional and national public authorities to begin using free and open multi-temporal Copernicus Sentinel-2 imagery as analysis-ready-data in daily workflows

This approach aims to meet pressing needs for monitoring, reporting, decision making spatial planning tools. SIMS will provide Web-browser-based access to a graphical user interface for interested users to monitor land cover changes without requiring programming skills, focusing first on soil sealing. Non-EO-experts will be able to develop and conduct custom multi-temporal (inter-and intra-annual) analyses using user-friendly interfaces. Core users will be included from the beginning and trained to use the SIMS prototype. The results will include condensed hot-spot map information products and the project will provide additional tools for seamless GIS integration, giving non-EO experts access to thousands of Copernicus data sets to  better inform reporting and decision making.
