Monitoring of conversion areas
02.08.2017
Dennis Roitsch – GIZ Internship Programme – February to July 2017
Task: Compile list of remote sensing systems for near real-time
monitoring of conversion areas in a future TLAS
1. Weak supply-chain control in the past
2. Logging often happened outside concession areas, causing forest
degradation
3. One focal point of the EU Lao-FLEGT negotiations
TWG Meeting
Remote sensing + on-the-ground inspections

Optical earth observation

Canopy openness is a
good indicator
Minimal seasonal
variation
Topography
complicates remote
sensing
Difficult climate
conditions: - Cloud coverage
- Atmospheric

• 143 Doves (micro-satellites) in orbit
• Weight 4kg (Sentinel 2: 1,140kg)
• Camera resolution between 3m and
5m per pixel depending on altitude
• Latest launch 14 February 2017
• Completely functional by end of 2017
• Automated time series analysis is
developed
• Requires annual renewal

• Developed by Joint Research Centre
(JRC)
• JRC shifts from Landsat 8 to Sentinel 2
(30m 10m resolution)
• FIPD/DOFI took part in trainings and field
missions already
• Shows logging & logging trails
• Free data and software

• Sentinel 2 and RapidEye (5m
resolution) compare well in detectable
detail
Challenges:
• Method requires bare soil Limited
time frame for detection
• Cloud-free images required
• No final accuracy assessment yet
• DeltaNBR also detects windbreaks,
dead bamboo, fire damage & vines

Discussion
02.08.2017
Technology:
• Phase I:
• Sentinel 2 data as long-term solution at the lowest cost for the
next 7 years
• Planet Labs is the easiest to handle & cloud based
• Phase II:
• With introduction of Sentinel and given the legal requirements,
there is no need for UAV utilisation
Organization:
• Define roles and procedures for verification in the TLAS
