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].
