Group 1 - The Resource No. 04 satellite, developed by the Ministry of Natural Resources, enhances China's three-dimensional earth observation capabilities by forming a satellite constellation with Resource No. 02 and 03 satellites [1][3] - The satellite is equipped with three cameras that capture images from different angles, allowing for the creation of 3D images similar to 3D movies, thus improving the accuracy of land space planning and disaster assessment [1] - The satellite's three-dimensional imaging capability allows for direct land space planning and precise measurement of terrain features, which is beneficial for assessing geological disaster impacts [1] Group 2 - The successful launch of Resource No. 04 will complete the observation network of China's civilian high-resolution optical mapping satellites, further enhancing the country's earth observation system [3] - The satellite constellation enables quicker emergency response capabilities, allowing for timely imaging of disaster areas, such as flood zones, by providing daily satellite passes instead of every three days with a dual-satellite network [5]

Core Viewpoint - The successful launch of the Resource 3-04 satellite enhances China's three-dimensional earth observation capabilities, contributing to improved natural resource management and disaster response [2][6]. Group 1: Satellite Launch and Capabilities - The Resource 3-04 satellite was launched successfully using the Long March 4B rocket, marking the 617th flight of the Long March series [1]. - This satellite is part of a constellation that includes Resource 3-02 and 3-03, aimed at obtaining high-resolution three-dimensional and multispectral images [2][6]. - Equipped with advanced three-line array cameras and high-precision laser altimetry, the satellite can perform high-accuracy three-dimensional mapping of ground targets [2][4]. Group 2: Applications and Benefits - The satellite enhances the ability to conduct land space planning in a more intuitive and realistic manner, allowing for slope calculations and geological disaster assessments [6]. - The three-satellite network significantly improves emergency response capabilities, enabling timely imaging of disaster areas, such as flood-affected regions [8]. - The Resource 3 series satellites serve various sectors, including ecological monitoring, urban planning, and low-altitude airspace management, thereby supporting scientific decision-making across industries [10][15]. Group 3: Efficiency Improvements - The use of satellite remote sensing has drastically increased the efficiency of ecological monitoring, allowing personnel to check up to 50 points daily compared to just 3-5 points previously [13]. - The technology facilitates rapid acquisition of extensive terrain and topographic information, which is crucial for construction project planning and management [15].
