Monitoring of surface water bodies by Sentinel and Open data

The main purpose of this research is interoperability of data from different sources and creation of innovative models with high value data such as satellite information and Earth data and solutions for public administrations, business and citizens. Building base data to inform and train stakeholders and promote the adoption of good practices and innovations in environmental monitoring is also a leading goal. An assessment was made of several surface water bodies that have acquired personal types of permits for use and construction. The methodology contains a model of Open data processing steps, which are published in the Open Data Portal of the State Agency "E-Government" in Bulgaria, satellite data from Sentune1-1 and Sentune-2 and terrestrial data from many different monitoring devices. Different formats are integrated, and for this there must be transdisciplinary knowledge and a complex approach. Composite images of optical and SAR data, TCT and terrestrial data from Environmental assessments and data from Basin Directorates in Bulgaria are combined. The model is further verified by the spectral characteristics of the objects, transformed images into dB (decibels) and statistical data. The interoperability of the data in this model will be a tool for restoring cooperation, coordination and communication between central and local administration, supply of services from the public sector, academia, business, NGOs and IT companies, development of solutions or information processing, in case of geospatial information and Environmental monitoring.
