Climate change – analysis of indicators
(11th International Conference “Environmental Engineering” (ICEE-2020), 2020)Progressing climate change poses a major threat to the Earth. According to a UN report, reducing global warming to below 1.5 °C offers hope for maintaining the current quality of human lives and for protecting the environment. ... -
Opportunities and barriers to the development of Poland in the field of renewable energy sources as compared to the European Union
(11th International Conference “Environmental Engineering” (ICEE-2020), 2020)Today, almost all of civilisation is based on energy. To a large extent, energy is being continuously acquired from non-renewable raw materials deposited in the Earth’s crust. Renewable sources provide alternative, infinite ... -
SLR and GNSS test field for global geodetic network assessment in Riga
(11th International Conference “Environmental Engineering” (ICEE-2020), 2020)The basic aim is to contribute to the world geodetic space in line with today’s scientific achievements. Riga geodynamic site is a thankful place for this, as it has long-term SLR observations and the longest GNSS records ... -
Investigation of forest area change in the 19th–21st century using military topographic maps
(11th International Conference “Environmental Engineering” (ICEE-2020), 2020)Long-term changes of the Earth’s cover are imperceptible. Several generations change, people do not see what had been there before they were born, they do not see what happens after they are gone, meanwhile, maps preserve ... -
Different approaches to coordinate transformation parameters determination of nonhomogeneous coordinate systems
(11th International Conference “Environmental Engineering” (ICEE-2020), 2020)During reconstruction and restoration of city geodetic networks, there is quite a common problem that is related to the nonhomogeneity of existing geodetic networks. In any city, local authorities operate with their ... -
