Why monitor ?
• Land use management
• Protected area management
• Forest resource management
• Forest Carbon assessment
3
Platforms – UAV
• User can own the system
– Coverage of large areas difficult
– Operational expenses; vehicles, staff, spare
parts
– Need to train and manage skilled staff
4
Platforms – VHR Satellite Imagery
• Very High Resolution Satellite Imagery
– Very effective, but high cost
– Some expertise required to process
6
Platforms- Mid resolution satellite
• Good trade off between cost and coverage
• Can detect changes in canopy,
construction of roads, skid trails
• May not identify individual tree loss
7
Platforms – Low and Mid-res
• Often free or very low cost
• Mainly useful for land conversion mapping
or mapping very large areas
