Following the successful 1st EARSeL Special Interest Group on Land Use and Land Cover (SIG LU/LC) and NASA Land-Cover/Land-Use Change (LCLUC) Program joint Workshop with more than 150 participants from 4 continents, the 2nd EARSeL SIG LU/LC and NASA LCLUC joint Workshop “Advancing horizons for land cover services entering the big data era” sets the questions towards and beyond the 2020 emerging challenges.
The workshop will take place on 6-7 May 2016.
New Earth Observation frontiers are being formed continuously by the dynamically changing expectations set by contemporary and expected developments in the geo- and bio-sphere as a counterbalance for pressures and demands emerging from a changing climate and the anthroposphere; driven in turn by the diverse and often volatile social, political and economic conditions around the globe. Environment, Food security, Energy, Health and Security require continuous, reliable and cost effective monitoring of the Earth’s surface and its resources. The 2nd EARSeL SIG LU/LC and NASA LCLUC joint Workshop is considered supportive to the objectives of the imminent following ESA Living Planet Symposium 2016 on 9–13 May 2016, as a brainstorming preparation and chance for specialists to formulate a common understanding and language prior to entering the wider discussions of the more diverse audience; in matters of background and expectations from land-cover products and the scientific community.
The Workshop is organized around four representative sessions, covering the latest advances; trending activities and future challenges in land-cover services in the big data era. The four sessions are:
- Harmonization of Sentinel-2 and Landsat products
- Mapping Land Cover and Land Use with cross-scale and cross-sensors approaches
- Challenges of Land Cover and Land Use Monitoring with Dense Time Series of EO Data
- EO benefits for ecosystem services and human wellbeing
Each session will open with presentations by distinguished keynote speakers who will trigger and set the floor for the discussion among all participants that will follow the keynotes. Each session will continue with poster presentation and conclude with discussion wrapping-up the key elements of the session and enhancing collaboration among the participants.
Sessions in detail:
SESSION 1: Harmonization of Sentinel-2 and Landsat products
Sentinel-2 and Landsat products represent the most widely accessible medium-to-high spatial resolution multispectral satellite data. Following the recent launch of the first out of two Sentinel-2 satellites, the potential for synergistic use of the two sources creates unprecedented opportunities for timely and accurate observation of Earth status and dynamics. Thus, harmonization of the distributed data products is of paramount importance for the scientific community. Activities to harmonize data products are on their way, yet more coordination is needed to allow the majority of users to easily and effectively include both data types into their work. The session discusses latest advancements and offers space for presenting new approaches and initiatives for products’ enhancement and distribution.
SESSION 2: Mapping Land Cover and Land Use with cross-scale and cross-sensors approaches
In the era of big data and pluralism of satellite sensors, fusion of data from multiple sources appears increasingly useful for Earth monitoring. However, difference in sensor types (e.g., optical vs. SAR), radiometric characteristics (e.g., Sentinel 2 vs. Landsat 8) and ground sampling distances cause challenges for synergistic use of available data products. This session gives room for presentation and discussion of approaches for multi-sensor analysis, including data and decision fusion approaches for mapping land cover and land use.
SESSION 3: Challenges of Land Cover and Land Use Monitoring with Dense Time Series of EO Data
The vast amount of data from Landsat-8 and Sentinel-2 a/b will lead to unprecedented density in time series of high resolution multi-spectral data. This valuable information is complemented by 30 years archived Landsat data at USGS. This creates new needs for the efficient handling of large volumes of optical images and approaches to translate temporal developments into land cover/use characteristics. This session is dedicated to aspects of dense and/or long time series with a focus on Landsat and Sentinel data.
SESSION 4: EO benefits for ecosystem services and human wellbeing
Terrestrial and marine ecosystems provide vital services for human kind. However, natural and anthropogenic pressures cause serious threats to ecosystems, leading to habitat degradation and loss of ecosystem services. Earth Observation (EO) data offer unprecedented capacity in timely and wide-extent monitoring of endangered areas, through the calculation of a variety of indicators and Essential Variables for fields including climate, biodiversity, and habitat monitoring. Open and harmonised data, e.g. following the principles of the Global Earth Observation System of Systems (GEOSS) and Copernicus program, offer new potential in ecosystem modeling, enhanced management and restoration, and capacity building. This session aims at presenting and discussing EO integration, applications, challenges and expected future work in the land-water-energy-climate nexus monitoring.
