CROWDVAL: Using Crowdsourcing and Innovative Approaches to Evaluate and Validate ESA’s Land Cover Products

Prime company: INTERNATIONAL INSTITUTE FOR APPLIED (AT)

The CrowdVal project had five main objectives: Develop new innovative sampling schemes that allow a stratification and bias removal via road networks and that take other constraints into account for in-situ data collection; Enhance LACO-Wiki and LACO-Wiki Mobile with the new sampling strategies, functionality for opportunistic map evaluation on the ground, and the addition of …

InSAR Short-Time-Series for Land Cover Classification

Interferometric (InSAR) short-time-series of Sentinel-1 SAR data acquired over central Europe were exploited in a new approach for the generation of large-scale thematic maps. Temporal features, extracted from the evolution of the interferometric coherence, together with backscatter, were used as input for a machine learning-based classifier. Three land cover classes were extracted: artificial surfaces, forests, …

World soils user consultation meeting

July 2, 2019 - July 3, 2019
ESA-ESRIN, Largo Galileo Galilei, 1
Frascati, RM 00044 Italy

Soil, the mixture of organic matter, minerals, gases, liquids and organisms that constitute the upper layer of the Earth, is key for life. Climate change, industrialization and urbanization, intensive agriculture and livestock farming are exercising pressures that might lead to soil degradation. Consequently, as highlighted from several international treaties, such as the Sustainable Development Goals, …

Infrastructures planning and monitoring user consultation conference 2019

February 26, 2019 - February 27, 2019
ESA-ESRIN, Largo Galileo Galilei, 1
Frascati, RM 00044 Italy

During the past decades infrastructures had to meet rapidly increasing users’ needs in terms of construction of new buildings, transportation, energy, water supply, sewer system and information networks. In this context, Earth Observation (EO) represents an opportunity for innovative science, applications and information services to face some of the issues related to such increase as …

A new method for unsupervised update of land cover maps

The possibility to operationally monitor the Earth’s land cover (changes) at high temporal resolution is nowadays given by EO multispectral dense time series available at global level, in particular Sentinel-2 and Landsat 8 data. Nonetheless, keeping thematic maps regularly updated is a complex and time consuming task. Large efforts have been devoted to date in …
