Comparison between UAV and Terrestrial Photogrammetry

Particulars UAV Photogrammetry Terrestrial Photogrammetry
Data acquisition Manual/Automatic/Assisted Manual
Image resolution High High
Ground coverage m2 – km2 m2
Visibility Highly positioned elements, rooftops, walls, limited when it comes to hidden objects. Walls up to the rooftop, allows photographing hidden objects, no visibility of rooftops.
Flexibility Weather – dependent, cannot fly to close to the objects around, problematic with too much greenery. Applicable in hazardous areas, works in cloudy, drizzly weather.
Price and operating cost Moderate Low – moderate
Geo-registration possibility High quality Medium quality
