FullCAM and High-Resolution Imagery: Maximising Carbon Project Outcomes

Summary

Australia’s carbon farming industry relies on FullCAM (Full Carbon Accounting Model) to estimate carbon sequestration and calculate Australian Carbon Credit Units (ACCUs). While FullCAM is the official methodology for national carbon accounting, its standard implementation using 25m resolution data leaves significant room for improvement. Here’s how high-resolution satellite imagery enhances FullCAM results:

• Detection Improvement: 30cm imagery reveals up to 23% more vegetation than standard 25m resolution, potentially increasing carbon credit yields
• Verification Efficiency: High-resolution imagery can reduce field verification requirements by up to 35%, lowering project costs
• Baseline Accuracy: 30cm and 50cm imagery provides more precise initial conditions, ensuring fair credit attribution
• Project Optimisation: Detailed vegetation mapping helps identify high-potential areas for interventions
• Best Resolution Options: Maxar WorldView-3 (30cm) and JILIN-1 (50cm) offer ideal resolution-to-cost ratios for carbon projects

Through Geopera’s Pera Portal, carbon project developers can access the optimal satellite imagery to enhance their FullCAM modeling and potentially increase ACCU yields.

What is FullCAM?

FullCAM (Full Carbon Accounting Model) is Australia’s official modeling tool for tracking greenhouse gas emissions and carbon stock changes associated with land use and management. Developed by CSIRO, this sophisticated system serves two critical functions:

1. National Carbon Accounting: FullCAM is the core model used to construct Australia’s National Greenhouse Gas Inventory for the land sector, tracking carbon changes across the continent since 1970.

2. Carbon Project Estimation: For project developers and landholders, FullCAM provides a standardised methodology to estimate carbon sequestration potential and calculate expected Australian Carbon Credit Units (ACCUs).

The model integrates several component systems:

• CAMFor – for modeling forest carbon systems
• CAMAg – for handling cropping and grazing systems
• RothC – for calculating agricultural soil carbon dynamics

FullCAM tracks all carbon and nitrogen flows through multiple pools including plants, debris, soil, products, and atmospheric exchanges. The system can model various scenarios including:

• Forest systems and wood products
• Agricultural cropping and grazing systems
• Afforestation and reforestation
• Deforestation processes
• Mixed systems such as agroforestry

For participants in Australia’s carbon market, FullCAM provides the critical link between land management practices and financial returns through carbon credits.

FullCAM’s Current Resolution Limitations

While FullCAM offers a robust framework for carbon accounting, its standard implementation faces significant limitations due to resolution constraints:

1. 25m Spatial Resolution

The current FullCAM implementation operates at a 25-meter spatial resolution, meaning each pixel represents 625 square meters on the ground. This coarse resolution creates several challenges:

• Missed Vegetation: Small tree clusters, scattered revegetation, and narrow vegetation corridors often remain “invisible” to standard analysis
• Boundary Imprecision: Ecosystem transitions and project boundaries lack definition
• Early Growth Blindness: Recently established vegetation may not register until it reaches substantial size
• Management Gap: Small-scale land management changes can go undetected

2. Conservative Carbon Estimates

These resolution limitations typically lead to conservative carbon estimates that may undervalue project outcomes:

• Small vegetation patches may be completely missed
• Mixed pixels containing both vegetation and non-vegetation are often classified based on the dominant cover type
• Early-stage carbon sequestration activities may be underrepresented
• Linear vegetation features like riparian corridors may be partially or completely overlooked

3. Verification Challenges

The resolution gap also creates inefficiencies in the verification process:

• Extensive field sampling is required to compensate for limited remote sensing detail
• Visual evidence for verifiers lacks sufficient detail
• Project boundaries may be imprecisely defined
• Small-scale management interventions are difficult to document

These limitations represent a significant opportunity for enhancement through higher-resolution imagery solutions.

The High-Resolution Advantage for FullCAM

Modern high-resolution satellite imagery offers a transformative upgrade to FullCAM modeling, addressing key limitations while maintaining compatibility with established methodologies.

Resolution Comparison

1. Superior Vegetation Detection with 30cm Imagery

Our premium 30cm satellite imagery from Maxar WorldView-3 provides approximately 6,944 times more detail than standard FullCAM resolution, revealing:

• Individual Trees: Clearly identify and count scattered trees across the landscape
• Small Vegetation Patches: Detect isolated vegetation clusters that contribute to carbon sequestration
• Early Regrowth: Identify and document revegetation in its early stages
• Precise Boundaries: Accurately delineate ecosystems and project areas

Carbon Impact: Field validation studies show that 30cm imagery typically detects 18-23% more vegetation than standard 25m resolution in mixed agricultural landscapes, potentially increasing carbon credit yields by similar margins.

2. Cost-Effective Enhancement with 50cm Imagery

For projects seeking significant improvements at a more accessible price point, our JILIN-1 50cm imagery delivers:

• 2,500× more detail than standard FullCAM resolution
• Clear identification of vegetation patches and corridors
• Excellent boundary definition
• Reliable detection of management activities

Carbon Impact: 50cm imagery typically identifies 15-20% more vegetation than standard 25m resolution in most Australian landscapes, offering an excellent balance of performance and cost.

3. Baseline Establishment Enhancement

Creating accurate baseline conditions is fundamental to carbon accounting. High-resolution imagery provides:

• Precise Pre-Project Documentation: Accurately record existing vegetation before project commencement
• Detailed Vegetation Structure: Document the size, density, and distribution of pre-existing vegetation
• Boundary Precision: Clearly define project boundaries based on actual landscape features
• Historical Context: When paired with our historical imagery archive, establish long-term vegetation trends

Carbon Impact: More accurate baselines ensure fair attribution of carbon gains, protecting projects from both over-claiming and under-claiming sequestration.

4. Verification Process Improvements

High-resolution imagery transforms the verification process by providing:

• Detailed Visual Evidence: Clear documentation of carbon sequestration activities
• Reduced Field Sampling: Less requirement for extensive ground-truthing
• Management Documentation: Visual evidence of interventions and practices
• Change Detection: Precise pixel-by-pixel tracking of vegetation development

Carbon Impact: Projects utilising high-resolution imagery typically report 25-35% reductions in verification costs while maintaining or improving compliance confidence.
