🎯 Learning Intention

Today, I will explore how accuracy and precision impact GIS work and practice habits that reduce errors in data collection.

✅ Success Criteria

I can explain the difference between accuracy and precision and identify at least two strategies to improve both in GIS projects.

🌍 Why Are We Learning This?

In GIS, even a small mistake in coordinates, labels, or data entry can throw off an entire analysis. Professionals build credibility by producing data that is both accurate and precise.

💡 Prompt:

Think of a time when a small mistake changed the outcome of something you were working on. What happened, and how could accuracy or precision have helped?

📚 Word(s) of the Day

Accuracy

• Definition: How close a measured value is to the true value.
• Used in a sentence: “The GPS unit had high accuracy, placing the location within 2 meters of its true position.”
• Why it matters: Ensures data reflects reality.
