Data Acquisition

Satellites capture-area imagery using passive sensors (np., optical, multispectral, hyperspectral) or active sensors (np., synthetic apertury radar, SAR). They provide regular revisit times, but their diffical resolution typically ranges from 30 m (Landsat) to 0.5 m (WorldView- 3). UAV, on thee division hund, carry compact sensors such as RGB cameras, multispectral images, thermal cameras, or units. They fly altexed of 500 m, requiints of 1m.

Data Synchronization

Integrating data from platforms with different spatilal, spectral, and temporal resolutions is complex. Satellite and UAV images must be closattely co- registered, which requires precise geolocation from both platforms. UAV often rely on GPS / IMU systems that can drift, especially in GPS- denied environments (e.g., forests or urban canyons). Misalignment of even a few meters can render fusion products unreliable.
