Based on the last year’s satisfying result, the project aimed to maintain and further improved the established systems and activities. The goals of this project included understanding the current costal waste in Taiwan, increasing the survey method of coastal waste and accumulating the data of the baseline. The core value of this project centered on the survey of monitoring coastal waste and the approaches to approximately calculating coastal waste. To find out the proper solutions, we analyzed the problems we were facing and referring to the literature of China, Japan and Korea. Through counselling and assessment, we went hand in hand with Environmental Protection Bureaus in cities and counties to improve the component analysis of coastal waste. The survey was conducted scientifically on coastal waste with remote sensing on Geographic Information System to analyze the change of objects along the coastlines. First, with the use of high-resolution images, aerial photography and the images of under clouds from Unmanned Aerial Vehicles (UAV), we analyzed the environmental information in multiple spatial dimensions and multispectral images. Next, through six areas demonstrating the image analysis and satellite or aerial photos captured by UAV to detect large areas of coastal waste, the recognition accuracy of coastal terrain reaches 70% and beach terrain 80%. Finally, to judge the source of coastal waste at different time and space, we imported the above-mentioned results to the GIS platform for image-overlapping display and took climate data from the Central Weather Bureau into consideration. To make the public aware of the seriousness of coastal pollution, we went to great lengths to provide environmental education of coastlines and to carry out the core value of coastal cleanup. We hoped the public realize that it was everyone’s duty to maintain the clean coastline. Three large-scale activities of coastal cleanup and six workshops for environmental education were held and the participants were up to 300. Reduction of waste from the source was our expectation. It was suggested that the public could join the coastal cleanup, simplify the ritual and reduce the waste. Concerning the system, emphases were placed on optimizing the system’s functions and boosting the usage frequency of the general public. Three main functions of the system included the notification of messy coast, the collection of coastal-cleanup information and the platform for displaying the layers of coastal waste. The above-mentioned functions, including maintaining the existing functions and establishing new ones, have successfully increased the user-friendliness of the system, the management effectiveness and monitoring the current coastal businesses.
