Floods occur throughout the world and are becoming increasingly frequent and dangerous. This is due to different factors, among which climate change and land use stand out. In Mexico, they occur every year in different areas. Tabasco is a periodically flooded region, causing losses and negative consequences for the rural, urban, livestock, agricultural, and service industries. Consequently, it is necessary to create strategies to intervene effectively in the affected areas. Different strategies and techniques have been developed to mitigate the damage caused by this phenomenon. Satellite programs provide a large amount of data on the Earth’s surface and geospatial information processing tools useful for environmental and forest monitoring, climate change impacts, risk analysis, and natural disasters. This paper presents a strategy for the classification of flooded areas using satellite images obtained from synthetic aperture radar, as well as the U-Net neural network and ArcGIS platform. The study area is located in Los Rios, a region of Tabasco, Mexico. The results show that U-Net performs well despite the limited number of training samples. As the training data and epochs increase, its precision increases.
Logistics, an activity as old as foreign trade, arose from the need and desire to consume products from other geographical areas, where various factors had to be coordinated to satisfy those requirements. Logistics evolved from being a routine and operational activity to something strategic, capable of generating competitive advantages that allow companies to differentiate themselves. In the search to generate and promote competitive advantages to meet the needs of users of the port of Manzanillo, it is important to develop new and better services for the most important container location in Mexico, helping to diversify the services provided. Another important factor, within this search for different services in a fast and reliable way with which such services can be available, will be the use of information and communication technologies (ICT's), using computer applications (APPs) designed to be executed in smart phones, tablets and other mobile devices. From the above, we are interested in developing an investigation through the implementation of an application that allows to identify and find companies in a fast and safe way, offering it to foreign people who need to find services related to direct and indirect activities that are provided in the port of Manzanillo, Colima. In the supply chain, the customer has become the most important part, aiming at their full satisfaction, providing the product or service they want at the right time, quickly and efficiently, i.e. in the context of total service and under strict quality standards.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
