Description | ||||||||
The EO data enables the financial management sector to regularly track changes in port activity patterns including cargo volumes, vessel traffic, and infrastructure development. By analysing these changes, financial managers can make informed investment decisions, assess the financial health of companies engaged in port operations, and identify emerging market trends. | ||||||||

Main processing steps | Monitoring changes in port activities over time is applicable by using VHR images with suitable temporal frequency. Then we can perform change detection analysis on the acquired satellite images to identify and quantify changes in the port's infrastructure, cargo volume, vessel traffic, and other relevant parameters. This analysis involves comparing two or more images taken at different times and highlighting the differences between them. The change detection analysis becomes more informative when we possess labelled data of the port. In addition to conventional change detection techniques, automated change detection methods using machine learning algorithms can be advantageous in this context. | |||||||
