Earth Observation Data
GIM GeoTrends Seminar EO – Vincent Tigny / Inge Melotte - June 2016
Provide evidences of the bombing of Kunduz hospital
▶ No clue WHAT data and HOW to procure
▶ DETAILED enough and high QUALITY!
▶ FAST!
Observe remote locations from your desk
Use case: International & NGOs
Select best route, locate and design the transmission towers ▶ ACCURATE and RECENT characterization of the TERRAIN
▶ PLS-CAD format
▶ ≠ project phases ≠ accuracy ≠ budgets
▶ Unreliable local surveyors and sometimes zones not accessible for geopolitical reasons
Plan high voltage overhead power lines
Use case: Utilities & Infrastructure

Drones and the law
THE SKY IS NOT THE LIMIT
▶ Specific obligations for drone operators and manufacturers ▶ Four categories: recreational & low/medium/high risk ▶ Safety inspired, based on prior risk analysis
Diversity in drone sensors

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
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
Satellite imagery
Capabilities & constraints
▶ + Extensive coverage ▶ + Broad spectral capabilities ▶ + Sensor stability
▶ - Relatively low spatial resolution (>30cm)
▶ - Image timing controlled by provider ▶ - Limited coverage in some regions ▶ - Imagery susceptible to cloud cover
Benefits of drones
