ReSAC built GIS Modules to publish and visualize project results of two Biodiversity and Ecosystems projects

ReSAC is responsible for the development and implementation of GIS Modules to publish and visualize project results of two projects – GRASSLAND and FEMA, which are financed by Program BG03 “Biodiversity and Ecosystems” and co-financed by the Financial Mechanism of the European Economic Area (EEA FM 2009-2014).

This type of data is first published for the entire territory of an EU Member State outside NATURA 2000 Network. Project results can be used by different users for research, analysis and decision making. Mapping data for grassland and freshwater ecosystems condition and their services in Bulgaria are published in two separate, specialized WebGIS Modules.

Overview of web-GIS interface

GIS Modules realization is based on open source software. The web-based architecture is compliant with the OGC standard. Geographic (spatial) information is provided by GeoServer, which includes outputs such as dynamic geographic data representation (Web-based GIS maps), access to spatial object attributes and search for attribute information. The flexibility of the proposed architecture provides OGC services to access spatial information (WMS and WFS), export to PostgreSQL / PostGIS DB of vector data and metadata to them, export to ESRI Shapefile, GML, GeoJSON and / or raster.

Databases are structured in separate groups in terms of ecosystem types, condition indicators and indicators of ecosystem services.

Users can use different base maps for visualization, such as satellite imagery or different types of maps.

Users can also visualize each indicator individually, to making reference to different attributes for each layer, and check the characteristics of the different types of indicators.

For more specialized users, it is also possible to use data in their desktop software via WMS and WFS services.

GIS modules are available at the following web addresses:
