Article
Unmanned Aerial Systems (UAS) have been recently used as a close-range remote sensing tool, providing high spatial and temporal resolutions compared to other remote sensing methods. Their abilities have constantly increased their use in many environmental studies with very satisfactory results. However, the acquisition of reliable information for a...

Marine conservation and management require detailed and accurate habitat mapping, which is usually produced by collecting data using remote sensing methods. In recent years, unmanned aerial systems (UAS) are used for marine data acquisition, as they provide detailed and reliable information through very high-resolution orthophoto-maps. However, as...

Full-text available
Marine habitat mapping is essential for updating existing information, preserving, and protecting the marine environment. Unmanned Aerial Systems (UAS) are an important tool for monitoring and mapping coastal and marine environment because of their ability to provide very high-resolution aerial imagery.Environmental conditions have a critical role...
Chapter
Coastline change and human activities in shoreline zones are two factors indicating the vulnerability and the quality of a coastal environment. In this article, coastline evolution and spatiotemporal differences on coastal touristic infrastructure are presented as two case studies. Both case studies have increasing interest among scientists monitor...
Article
Full-text available
Aerial surveys in coastal areas using Unmanned Aerial Vehicles (UAVs) present many limitations. However, the need for detailed and accurate information in a marine environment has made UAVs very popular. The aim of this paper is to present a protocol which summarizes the parameters that affect the reliability of the data acquisition process over th...

In the last year, the Greek islands of the eastern Aegean Sea were the main entrance points used by refugees arriving in the EU. The crossing between Turkey and the eastern Aegean islands is carried out using mostly small inflatable boats. Additionally, wooden and plastic vessels of various sizes are abandoned at the beaches upon arrival together w...

Conference Paper
The collection of detailed and accurate information about marine habitats and flora species is crucial for mapping, monitoring and management of marine and coastal environments. Remote sensing is widely used to collect information at marine environments, while in recent years the potential use of UAS for mapping is examined. The aim of this paper i...
Conference Paper
Abstract Last years the role of Unmanned Aerial Systems becoming more and more crucial in a wide variety of scientific aspects that need fast and reliable geodata. Nowadays UAS have a prominent role in post-earthquake damage assessment as they are capable of collecting high in resolution data for mapping the results of a catastrophic event. The imp...
Conference Paper
Seagrass meadows play a vital role in coastal ecosystems health as constitute an important pillar of the coastal environment. So far, regional scale habitat mapping was implemented with the use of freely available medium scale satellite images (Sentinel-2 or Landsat-8). The Unmanned Aerial Systems (UAS) have increase the spatial resolution of the o...
Conference Paper
The significance of coastal habitat mapping lies in the need to prevent from anthropogenic interventions and other factors. Until 2015, Landsat-8 (30m) imagery were used as medium spatial resolution satellite imagery. So far, Sentinel-2 satellite imagery is very useful for more detailed regional scale mapping. However, the use of high resolution or...
Conference Paper
Coastline change and marine litter concentration in shoreline zones are two different emerging problems indicating the vulnerability as well as the quality of a coastal environment. Both problems present spatiotemporal changes due to weather and anthropogenic factors. Traditionally spatiotemporal changes in coastal environments are monitored using...
Article
Full-text available
One of the most important linear features on the monitoring of coastline is critical. The study of coastal system processes and coastal zone environmental management requires the information about coastlines and their changes. In this study, a methodology that extracts coastline efficiently by processing high-resolution orthophotos derived by UAV i...
Conference Paper
Full-text available
Coastal environments and their topographic changes have increasing interest among scientists that monitoring degradation in sensitive coastal areas. Topographic changes in beach zones are observed mainly after severe events due to the action of the sea and sea waves. Additionally, human interaction can be a cause of the coastal environment material...

The subject of this proposal is based on a business idea of developing two different types of Unmanned Aircraft Systems (UAS). - The first UAS will be suitably equipped with sensors and other recording instruments and an integrated processing system for the purpose of reviewing - recording, processing data and identifying various unknown "targets" in marine areas to prevent piracy in commercial ships. - The second UAS system to be developed at this proposal will be a little flexible and easy to use by non-specialist operators. In particular, it will be developed by its handlers in case that the ship is occupied by pirates, so to follow the vessel at a suitable height and distance for the first significant period of the ongoing piracy by relaying to appropriate frequencies an S.O.S. signal, and critical information. http://www.arsx2.com/en
