2.3.2. Dataset

The dataset is divided into two parts: aerial images and satellite maps. The aerial images are collected by the self-built UAV platform mentioned above, with a total of 3960 images. The number of aerial images is then expanded to 10,000 by data enhancement processes including panning, zooming, blurring, and flipping, which cover categories such as mountains, forests, rivers, lakes, coastlines, urban intersections, playgrounds, factory buildings, single-family buildings, neighborhood buildings, viaducts, parks, roads without green belts, roads with green belts, etc. Satellite images corresponding to the aerial images are taken from publicly available satellite images.
