Aerial Surveying and Mapping is the process of collecting geospatial data from above the Earth’s surface, typically using unmanned aerial vehicles (UAVs), or manned aircraft, to capture aerial imagery and other data. This data can then be used to create detailed maps, 3D models, and other visualizations that provide critical information for a range of industries, including urban planning, construction, agriculture, and environmental management.
Understanding Aerial Surveying and Mapping
Aerial surveying and mapping involves the use of a variety of technologies, including digital cameras, LIDAR (Light Detection and Ranging), and other sensors. The data collected from these technologies is processed using specialized software to create detailed digital maps, 3D models, and other visualizations.
Aerial surveying and mapping is typically conducted using unmanned aerial vehicles (UAVs) or manned aircraft. UAVs are particularly useful for smaller-scale projects, as they are less expensive to operate and can be flown at lower altitudes to capture higher-resolution imagery. Manned aircraft are typically used for larger-scale projects, such as mapping entire cities or regions.
