BIO_SOS working objectives
The development of pre-operational automatic HR and mainly VHR EO data processing and understanding techniques for: LCLU and LCLU change maps production as an improvement
of GMES core services.
The development of an ecological modelling framework at both habitat and landscape level to combine EO and in-situ data for:
Habitat and Habitat change mapping (GHC and Annex I) Biodiversity indicator extraction. Scenario analysis
as an extension of GMES downstream–services
BIO_SOS peculiarities The system adopts deductive learning schemes, i.e. it based
on expert knowledge elicitation to fill the gap between domains
Ontologies and semantic networks are used for LCLU and Habitat class description; LCLU to Habitats translation (domain ontologies)
The Food and Agriculture Organization Land Cover Classification System (FAO_LCCS) is adopted for LCLU classification since it provides the best description of natural vegetated classes compared to other taxonomies (e.g. CORINE) (Tomaselli et al. 2013).

BIO_SOS peculiarities
The proposed architecture is multi-modular. The modules have been developed independently to reduce the risk of a major project breakdown
Based on expert knowledge elicitation, validated LC/LU maps can be integrated with in-situ data to provide: General Habitat Category (GHCs) and Annex I maps LCLU and habitat change maps
Pre-existing LCLU maps produced by photo-interpretation and in-field campaigns (e.g. LCLU and in-situ data) can be exploited mainly in Mediterranean regions were habitat maps are often not available

WP 6: EODHaM modelling modules development
Task 6.4Ecological Niche Modelling (ENM)
Aim:To investigate the relationship between the GHCs, landscape features, pressures, and the abundance and composition of some
taxa, both animals and plants
D6.6 “Selected bioindicators”
D6.7 “ENM” Aim:Verify if GHCs can provide an useful link
between EO data and the species distributions (species of conservation interest or representing
biodiversity threats)

Ecosystem state assessment (Task6.3) Software generation (in R) to simulate spatially distributed
water connectivity: to relate slope gradient to upslope basin area to deal with roads as connectivity modificators
Impact of ecosystem fragmentation – metapopulation
Methodology to identify locally recognizable (Task 6.8) pressures and quantify their impact on habitats extract pressure growth

BIO_SOS achievements EODHaM System Designed and Implemented
1st stage: spectral rules 2nd stage: context-sensitive features and spectral rules 3rd stage: translation of LCLU to GHCs and Annex 1
Potential to include expert knowledge, ancillary data
Open source software with translation out of commercial software (Python)
Scalable: UAS, WV2, Landsat, MODIS
LCCS/GHC maps generated for primary BIO_SOS sites
Capacity for change detection: Change in class Change in indices (pixel/object-level).
New accuracy assessment tools, approaches and data
BIO_SOS contribution to GEO Task BI-01
Long-term baseline data (e.g., thematic maps at 1:5000 scale or finer) of land covers and habitats as well as new automatic, standardized, rapid and cost-effective monitoring techniques.
A modelling framework for evaluating the combined impact that different drivers affecting soils and/or vegetation may have on biodiversity.
BIO_SOS products will be more familiar to the End Users since they are built on their expertise and can be improved as they further engage with the process
BIO_SOS contribution to GEO Task BI-01
Continuity with EBONE and links with Ms.Monina for biodiversity monitoring at regional level: VHR GHC and Annex I.
FAO-LCCS taxonomy is used as brokering tools to combine different domains (e.g. LCLU and habitats)
The output products will be made available for policy decision making; to follow up impact of existing policies and meet the commitments related to European Directive obligations.
Conclusions and lessons learnt
Multi-spectral/temporal EO data are more effective and less costly than available single-date hyper-spectral data.
WorldView2 data and LIDAR seems very useful for habitat monitoring.
More research is still needed for biodiversity indicator extraction from VHR imagery
Protocols for in-situ data collection should be: harmonized based on ecological modeling (e.g. niche modeling) agreed with Management authorities who institutionally collect data
