2D Drone Mapping: Techniques, Tools, and Key Applications
What is 2D Mapping?
2D mapping involves capturing a two-dimensional representation of an area, typically from a bird’s eye view, to provide comprehensive spatial information without distortion. Using photogrammetry and image stitching, 2D maps can be generated from a series of images, often captured by drones, to create an orthomosaic map that accurately represents the area. This mapping technique is crucial across various industries, from environmental monitoring to urban planning, agriculture, and construction. With advancements in AI technology and drone imaging systems, 2D mapping has become more accessible and reliable, paving the way for real-time data collection and informed decisions based on data insights​.
