Monitoring coastal environment, particularly landscape and vegetation on coasts and beaches, is considered to be important because they change rapidly and drastically due to the natural cycle and artificial pressures. Several monitoring tools for the coastal zone environment have been developed to date. However, most of them require heavy instrument and are often lacks cost effectiveness. In order to achieve cheaper and handy spatial monitoring, we developed video and camera recoding devices attached to a motor-powered paraglider. It can provide clear and sharp photographic data from very low to relatively high altitude. The resolution of the data is down to 5cm depending on its altitude and recording device. The experiment and development of monitoring equipment were carried out in 1999 and 2000 to test its efficiency and effectiveness. The results showed that the photographic data could be utilized for image analysis, for example measuring changes in coastal vegetation, monitoring artificial alternation on foreshore and counting litters on beaches. It also demonstrates cost effectiveness because motor-powered paraglider flights do not cost very much in comparison to ordinary aerial photograph by helicopters and airplanes. This monitoring method can be used for NPO and NGO to track changes in coastal environment regularly with relatively lower cost. Furthermore, the photos taken by this device can be amalgamated and attached to the map by using Arc view GIS software based on the positioning data obtained from a camera or VTR that is equipped with DGPS (differential global positioning system).

监测沿海环境，尤其是沿海和海滩上的景观和植被被认为很重要，因为它们由于自然循环和人造压力而迅速而急剧变化。迄今为止，已经开发了几种针对沿海地区环境的监测工具。但是，其中大多数需要重型仪器，并且通常缺乏成本效益。为了实现更便宜，方便的空间监控，我们开发了连接到电动机滑翔伞的视频和摄像头设备。它可以从非常低到相对较高的高度提供清晰而尖锐的摄影数据。数据的分辨率取决于其高度和记录设备。监测设备的实验和开发是在1999年和2000年进行的，以测试其效率和有效性。结果表明，可以将摄影数据用于图像分析，例如测量沿海植被的变化，监测前岸上的人工交替并在海滩上计数垃圾。它也表明了成本效益，因为与直升机和飞机的普通航行照片相比，电动驱动的滑翔伞航班的成本不高。这种监视方法可用于NPO和NGO，以定期跟踪沿海环境的变化，成本相对较低。此外，该设备拍摄的照片可以通过基于从配备DGPS（差分全局定位系统）的相机或VTR获得的位置数据来合并并连接到地图上。
