Keynote Speakers

Elif Sertel

Elif Sertel is a Professor (since 2016) at the Geomatics Engineering Department of Istanbul Technical University. She conducted her PhD dissertation work at Rutgers University, the USA, as a Fulbright Scholar and investigated the impacts of land cover change on regional climate. She was a post-doctoral researcher at Rutgers University in 2008 and explored the effects of water table dynamics on the regional climate.
She held the Director position at Istanbul Technical University – Center for Satellite Communications and Remote Sensing (ITU-CSCRS) between 2012 and 2021, where she was the Vice-Director between 2009 and 2012.
Her research focuses on the application of geospatial technologies, namely Remote Sensing and Geographic Information Systems (GIS), to solve environmental issues, generate decision support systems, understand the interactions between the land surface and climate and the impacts of humans on climate, primarily due to the land cover change caused by urbanization. For the last five years, she has mostly worked on deep learning, geospatial data analytics, and environmental problems such as soil salinity and droughts. She has extensively used geostatistical and spatial methods for the quantitative impact analyses of multidisciplinary applications, specifically in agriculture, forestry, and urban planning. Recently, she has also been researching the application of GeoAI to spatial challenges in the Digital Humanities.
Prof. Sertel received the Outstanding Young Scientist Award from the Turkish Academy of Sciences in 2017 (TÜBA-GEBİP) and the TUBITAK Incentive Award in Engineering from TUBITAK (The Scientific & Research Council of Turkey) in 2021; the first scientist in Turkey to receive both awards in her field.
She is in the Editorial Board of “Geocarto International” and “International Journal of Digital Earth” journals. She is acting as a Guest Editor for the special issue “Advances in Large-Scale Computer Vision for Earth Observation Data Analytics” in the “International Journal of Applied Earth Observation and Geoinformation”

Title: Earth Observation Data for Geospatial Artificial Intelligence
The number of Earth Observation (EO) satellites in orbit has grown significantly with the contribution of the NASA and ESA Earth Observation programs and numerous commercial initiatives. As a result, there is a substantial increase in satellite image data volume and variety. Cloud-based data provision and processing platforms have facilitated access to an enormous amount of high-resolution Remote Sensing (RS) images and opened a new era in Geospatial Artificial Intelligence (GeoAI)-based RS research.

This talk will provide different GeoAI methods implemented to EO data to support geospatial analytics processes. The first application will be on RS image super-resolution (SR). The spatial and spectral resolution of EO satellites are generally not at the desired high level due to the limitations on optic and sensor technology and high costs; therefore, it is crucial to develop software-based algorithms to improve the spatial and spectral quality of the satellite images, which emphasize the importance of SR. Different deep learning (DL) based methods for Single-frame and Multi-frame RS image resolution will be comprehensively explained. The second application will be geospatial object detection, in which airplane detection will be focused on by providing results of various YOLO architectures. The third GeoAI application will be on geospatial object segmentation, in which a new building detection data set will be presented and results of the comparison of different DL architectures for the accurate extraction of buildings for this new data set and widely used Massachusetts and INRIA data sets will be discussed. The last application will be on Land Use/Land Cover segmentation from high-resolution multi-sensor data, in which results of multi-modal and multi-task segmentation to reliably map extensive LULCC classes will be presented. Finally, future directions and insights on GeoAI data sets and methods for different applications will be discussed.

She has been guest editor of the special issue “Advanced Remote Sensing Data Analysis for Sustainable Development” of the IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing. She is a member of the scientific and programme committee of the IEEE International Geoscience and Remote Sensing Symposium (IGARSS) and the SPIE International Symposium on Remote Conferences, respectively, and is also a referee for several international journals. Dr Paris won the prestigious Symposium Prize Paper Award (SPPA) at the International Symposium on Geoscience and Remote Sensing 2016 (Beijing, China, 2016) and the International Symposium on Geoscience and Remote Sensing 2017 (Fort Worth, Texas, USA, 2017).

Title: The scarcity of labels for satellite images: opportunity and challenges of multi-source geo-tagged data
Recent advances in Earth observation data and artificial intelligence are paving the way for extremely detailed, near-daily environmental monitoring at very high spatial resolution. This possibility, however, is limited by the need for huge, constantly updated annotated data sets, collected on a large scale and customized for the environmental analyses under investigation. However, the recent abundance of real-time geospatial data continuously collected by social sensors (e.g. social media platforms), crowdsourced data (e.g. openstreetmaps) and the increasing production of global thematic maps are changing the paradigm of reference data collection. Although extremely valuable, these data are not 100% reliable, thus introducing in the reference database a degree of uncertainty that must be taken into account. This talk will provide an overview of the limitations, challenges and opportunities offered by all these multi-source geo-tagged datasets that can relieve the labeled data scarcity bottleneck.
