Zoom earth1/13/2024 ![]() ![]() Volkerak dam, also part of the plan, is visible in the image at the eastern end of Haringvliet. The dam was constructed as part of the ‘Delta Plan’ – a number of dams, sluices, dikes and barriers to reinforce the coastline. Haringvliet dam is visible as a white and green bridge closing the mouth of the river. The large body of water south of Rotterdam is Haringvliet. Moving north along the coast lies the town of Noordwijk, which is home to ESTEC, ESA’s technical centre, where new missions are designed, their industrial development is managed and, in some cases, the spacecraft and instruments are tested. Other cities pictured include Utrecht northwest of Rotterdam and The Hague northeast of Rotterdam. Rotterdam is Europe’s largest port and the gateway to some 450 million customers. Rotterdam, the country’s second largest city after Amsterdam, can be seen as a grey area near the centre of the image, straddling the New Meuse River, visible as a black line. The white dots on the left are offshore wind farms. Their colours indicate when they were captured by the satellite, as noted above. ![]() The coloured dots in the black of the North Sea are ships. Water surfaces usually appear dark or black. Parts that appear grey or white depict little or no change. For example, the green means that the vegetation was particularly lush when the January image was acquired. The combined images, with their different colours, help identify changes that have occurred between the acquisitions. This multitemporal picture is a combination of three radar images, each assigned to a colour channel: red for the image acquired in August 2022, green for the second image taken in January 2023, and blue for the last image from June 2023.

The script will skip existing files during downloading and cropping.ImageJ is a useful tool for adjusting the crop defaults.Open geoSatView.R to edit further from defaults as needed.The script can also be run from an empty directory, as long as you set that directory as R's working directory. The script is also a useful reference for those looking to manipulate images in R and create videos.
