What is ground-based remote sensing?

Ground-based remote sensing is a measurement technology, which aims to obtain the information of the earth's surface by using remote sensors such as satellites and aviation platforms. It can provide useful information support for civil engineering, architectural design, urban planning and other fields. Compared with traditional aerial photography or ground survey methods, this technology is more cost-effective, and can cover a larger area and provide more accurate and comprehensive data.

Ground-based remote sensing usually uses lidar, panorama camera, high-resolution satellite images and other equipment to obtain data of specific positions on the earth's surface. These data can be used to generate digital elevation model, three-dimensional terrain model, ground object classification, deformation monitoring and other products. In civil engineering, ground-based remote sensing can help engineers understand the influence of natural factors such as geological conditions, topographic characteristics, glacier melting and sea level rise on land use; In urban planning, it can help to determine the best location and layout of roads, parks, buildings and other infrastructure.

In a word, ground-based remote sensing is a fast, efficient and accurate measurement technology, which can provide important geographic information and data support for various fields.
