Success Stories

Landslides

Siriu area, in the central part of Romania, presents a long history of landslides processes. During recent years, several landslides affecting the water dam and the surroundings have been reported in the area. The water dam construction triggered slopes instability that led to one major landslide blocking the lake in 2006 and other similar phenomena...

Wetlands

The anthropic changes that occurred in Danube Delta between 1950 and 1990 due to the need to exploit natural resources and increased navigation had a negative effect on the hydrological regime. The new water channels led to modifications of the water flow. The efforts to protect this area are correlated with international politics and strategies...

Mining Zones

In Ocnele Mari (Romania) and the surrounding area, mining has caused numerous environmental and related social problems. In 2009, TERRASIGNA developed a monitoring service to accurately detect the starting of the ground subsidence conditions before the actual catastrophic event to take place, thus contributing to the mitigation of the damages caused...

Critical Infrastructure

The nuclear power plant at Cernavoda is unique in Romania. Due to its strategic profile, one of the main concerns of the authorities is the nuclear safety and security. Special standard are to be followed in order to insure the long term (60 years) functionality in safe conditions. TERRASIGNA used EO techniques based on satellite imagery...

Land deformation monitoring in urban areas

Different natural phenomena (earthquakes, landslides) or urban human activities (such as the construction of urban infrastructure like metro lines) can have as consequence ground deformations that can affect the buildings and the urban infrastructure. Therefore, monitoring the areas susceptible to be affected can bring valuable information...

Urban area evolution

The development of the urban areas in time can be monitored using space imagery in a reliable and efficient manner. Having the World Bank as client, TERRASIGNA provided maps showing the evolution of the most important and biggest urban areas in Romania, offering information like the constructed areas evolution within the last 2 decades or the...

Agriculture

Agriculture is one of the domains that successfully use the space technologies in order to achieve better results. Applications and services can be built to support farmers in a better management of their lands, more efficient and less costly production, together with a relevant crop monitoring. There are a series of legal, meteorological or...

Thematic Exploitation Platforms

Earth Science Data Access and Processing Service for Black Sea (ESPOSS) ESPOSS is a Black Sea dedicated web application (client and server technology) for Earth Science (ES) data access and processing, based on Open Geospatial Consortium (OGC) standards for data retrieval (WCS, WFS) and server-side processing (WPS). The application is...

Satellite Image Time Series

Satellite data proved to be of high importance in understanding and monitoring the environment. The images recorded using sensors on-board satellites represent important resources not yet exploited to their full potential. Due to significant technological improvements, every new EO mission brings a boost of information due to the available high...

Content Based Image Retrieval

The latest investments and developments in the space technologies have as result the increase of satellite data amount available for the different applications and services to be developed. In order to easy the access to the imagery most appropriate for the user’s need, several methods for image retrieval have been developed, using image...

Visual data mining

VDM is a generic term to refer to visual data exploration tools, which allows interactive data presentation in order to increase users' capabilities to understand the information content of large data sets of images and extract meaningful, relevant semantic clusters, together with quantitative measurements presented in a suggestive, visual...

Ground Based Radar

Radar imagery provides solutions in measuring the deformations of the Earth surface, either produced by natural phenomena (earthquakes, subsidence), or by extensive mining, deforestation and other human activities. In providing the needed input data, spaceborne systems are inefficient for a number of situations: the revisit time for a typical...
