Capabilities & constraints
Drone imagery
▶ + Cost-effective (smaller projects) ▶ + (Frequent) acquisitions on demand ▶ + Very high spatial resolution (cm) ▶ + Unaffected by cloud coverage
▶ - Small single-flight coverage ▶ - Restrictions by drone legislation ▶ - Operations susceptible to bad weather ▶ - Human resources needed
![Page 25: Environmental mapping: drones, aerial or satellite images?](https://reader031.vdocument.in/reader031/viewer/2022022414/587163eb1a28ab58758b4eaf/html5/thumbnails/25.jpg)
Aerial imagery
Capabilities & constraints
▶ + Large single-flight coverage ▶ + High spatial resolution (>7cm) ▶ + Broad spectral capabilities
▶ - Typically extensive (not for smaller projects)
▶ - Image timing controlled by provider ▶ - Operations susceptible to bad weather ▶ - Flight approval required ▶ - Aircraft availability may be limited in
remote regions
