Interpretation log
One row per feature you identify on the image, with how sure you are. Runs in your browser.
| Feature seen | Interpretation | Confidence | |
|---|---|---|---|
Summary
3 features logged. Low-confidence calls are the ones to verify on the ground or with better imagery before you rely on them.
How to use this calculator
- For each feature you pick out on the imagery, note what you saw and what you think it is.
- Rate your confidence High, Medium or Low.
- Read the tally and the high-confidence percentage to see how solid your interpretation is.
How it works
The log counts how many features you rated High, Medium and Low, and works out the share you were confident about.
It’s a habit-builder: photo interpretation is judgement, so recording confidence tells you which calls to verify before you trust them.
Worked example
A faint line in scrub. A clear dark linear feature → ‘sealed road’, High. A faint line in scrub → ‘old fence?’, Low. The Low ones are what you check on the ground or with better imagery.
Frequently asked questions
What should I do with the Low-confidence rows?
Treat them as unverified. Confirm them with ground truthing, higher-resolution imagery, or a second source before using them in a plan or dataset.
Is this official course material?
No. It is free study support mapped to surveying course levels — not official North Metropolitan TAFE content or advice. Always follow your lecturer and the official assessment brief, and check your own working.
