Abstract. During the last years, various methods and techniques have been used to estimate the seafloor topography with high accuracy. The topography is considered an important component for marine applications since several activities and infrastructures are being carried out at the bottom, column and surface of the sea. In this, study, freely and open distributed optical satellite images were used to obtain bathymetric data for shallow waters, (until 30 m below sea level) based on timeseries analysis of multispectral Sentinel-2 datasets. The ratio transform algorithm was implemented for twelve (12) monthly images covering thus a whole year. The different generated Digital Terrain Models (DTMs) were compared with high resolution LIDAR measurements. The results showed that bathymetry can be obtained from satellite data within a Root Mean Square Error (RMSE) ranging from 1.39 up to 2.56 m while more accurate results were generated during the summer period.

Natural and physical hazards accelerate the deterioration of asphalted surfaces. Climatic factors are unavoidable and can affect the properties of asphalt mixtures, making them weaker and less durable. Thus, continuous monitoring of bituminous surfaces is something that can reduce the risks of public health. Remote sensing techniques have become an effective, noninvasive method for early detection of damaged asphalt pavements. This paper outlines a range of different remote sensing methodologies that can be used to monitor asphalt road pavements. This is complemented by the use of field spectroscopy for the examination of asphalt pavements of varying age and conditions. The results of the study found spectral differences regarding asphalt defects, such as physical cracking, patched cracking and polishing. These spectral changes were examined through ''in-band'' simulation analysis of the Landsat 7 ETM? sensor, using appropriate relative spectral response filters, concluding that the ratio band 5/band 1 can be used to distinguish asphalt pavements of different date of construction and condition.

Marine Spatial Planning (MSP), which is in concept similar to land-use planning, is a public process by which the relevant Member State’s authorities analyse and organise human activities in marine areas to achieve ecological, economic and social objectives. MSP aims to promote sustainable growth of maritime economies, sustainable development of marine areas and sustainable use of marine resources. This paper highlights the importance of MSP and provides basic outcomes of the main European marine development. The already successful MSP plans can provide useful feedback and guidelines for other countries that are in the process of implementation of an integrated MSP, such as Cyprus. This paper presents part of the MSP project, of which 80% funded by the European Regional Development Fund (ERDF) and 20% from national contribution. An overview of the project is presented, including data acquisition, methodology and preliminary results for the implementation of MSP in Cyprus

Spatial Planning is a critical tool for land management and is extensively used in all developed nations. The Marine Spatial Planning (MSP), at the European Union (EU) level, is based on Directive 2014/89/EU of the European Parliament and Council of 23 rd July 2014 which establishes a common framework for MSP in the EU, which each Member State is called to apply in relation to the maritime space under its jurisdiction (marine waters). In this paper the overall results from the "Cross-Border Cooperation for the development of Marine Spatial Planning" project are presented for the area of Cyprus. A variety of activities fall within the MSP such as maritime transport routes and traffic flows, exploration, exploitation and extraction of energy resources, tourism, underwater cultural heritage etc. In addition, the legal framework, activities maps are also shown. The variety of conflicts maps for the area of Limassol are illustrated both in 2D and 3D. A hypothetical scenario of Limassol town in Cyprus as an energy center is presented based on the overall results. The paper ends with some conclusions regarding the framework of MSP in Cyprus.
