Calimate – start right.
Improve reliability in the field — regardless of who performs the estimation
Calimate is a web-based training tool that reduces variation in vegetation cover estimations and strengthens the quality of the data used for analysis and decision-making.
What is Calimate?
Calimate is a web-based training tool designed to help field inventory personnel systematically calibrate their vegetation cover estimations.
By working with realistic image material, comparing estimations with reference values and receiving immediate feedback, users improve both precision and consistency over time.
The method is based on scientifically validated principles and has been shown to reduce estimation error from up to 14% to around 3%.
- Web-based
- Scientifically grounded
- Improved consistency
- Instant feedback
- Scalable for teams
Why consistency matters
Small differences in individual estimations can lead to significant variations in data quality, analysis and decision-making.
Differences in interpretation
The same area may be estimated differently depending on experience and reference frames.
Reduced data reliability
Variation in field assessments makes comparisons and long-term monitoring more difficult.
Time-consuming calibration
Lack of a shared reference leads to discussions and adjustments.
How Calimate works
1. Practice using real images
Users estimate vegetation cover using images from a diverse dataset.
2. Get instant feedback
Each estimation is compared with a reference value and visualised.
3. Improve consistency over time
Users develop more reliable estimation skills while organisations gain more consistent data.
