In the national water resource management, the data is the basis for the calculation of water reserves. In a large scale and wide, searching the data will require substantial funding, as well as with the updates. Data colecting becomes a problem and not useful if not managed with the system efficiently and effectively. Technology occupies an important role in accelerating the work, such as remote sensing technology using a satellite to determine the condition of forests and water, or a weather that can see the concentration of clouds and wind movement. Determination of catchment areas of water and protected areas, may of them using remote sensing technology. Water treatment technologies for drinking water and the development of efficient recycling technology of waste water, is very supportive in increasing water use efficiency. Technological developments also influence government policy and the implementation of water resource management. National Policy of Water Resource Management is influenced by economic factors, environmental sustainability and socio-cultural conditions. The role of technology are  facilitate, accelerate and improve the efficiency of the process, so that the process can be more economical and environmental impact is reduced, and does not conflict with the socio-cultural conditions. Keywords : Kebijakan nasional sumber daya air, potensi sda, teknologi pengolahan air

This paper proposes a ground-based videometric method and system for measuring the glide track of landing aircraft in real time. The proposed method is applicable for large-scale measurement via regional relays with multiple cameras. Its measurement ranges from kilometers away to the landing point, and it simultaneously fulfills the real-time measurement of the position and trajectory of aircraft. The real-time measurement result of the actual aircraft landing process shows a deviation from DGPS(Difference Global Positioning System) as small as 20 cm in the measuring region of 1 km. The proposed measurement method for aircraft landing track based on videometrics can establish a new type of landing aid system removed from radar and GPS.

UAV aerial remote sensing system has the characteristics of strong real-time, flexible, high image resolution and low cost, which can be applied to map mapping tasks under various terrain. In this paper, the key technology of UAV Remote Sensing Surveying and mapping, the process of image processing, the research of mosaic method and the field application of remote sensing technology are studied. Aiming at the characteristics of UAV image with high resolution and small image frame, three methods of image map making are proposed, namely, single image geometric correction method, mosaic correction method and aerial triangulation method. This paper focuses on the key technical problems of the three methods, and makes a comprehensive analysis and experimental verification of each method from the aspects of mapping effect, accuracy and efficiency. The experimental results show that the UAV remote sensing technology can meet the real-time basic surveying and mapping data requirements of urban mapping. This method can meet the needs of 1:500 high-precision mapping. The system can reduce the cost and improve the usability when it is used to update the basic data of Urban Surveying and mapping.

In conducting mine detection experiments using our prototype robot COMET-1, we developed end effectors on the robot’s working legs. When detecting a mine, a robot must step safely and stably without hitting it. For this study, we created a simulation model to test the movement of a robot having an optical proximity sensor on each foot and used a walking algorithm having compliance control. We verified its efficiency in walking experiments. We also studied the use of remote sensing technology with an IR camera combined with other sensors. Tests with trial mines were used to study the detection of an IR camera and studied technologies for collecting and processing image data in real time for optimum mine detection.
