Topic: Raster vs Vector, Spatial Resolution, Metadata, and Common GIS Errors**

Essential Question:

How do different types of spatial data work, and what errors can occur when GIS layers do not align correctly?

🎯 Learning Intention

I will distinguish raster and vector data, interpret spatial resolution, and identify common GIS errors such as misalignment, projection mismatch, and incorrect metadata.

✅ Success Criteria

• I can explain the difference between raster and vector data.
• I can define spatial resolution and how it affects image quality.
• I can read metadata to understand how a dataset should be used.
• I can diagnose common GIS layer alignment problems.

📚 Vocabulary (Students Copy)

Raster Data — Pixel-based data (imagery, elevation).

Vector Data — Points, lines, and polygons representing discrete features.

Spatial Resolution — Size of each raster pixel; controls detail level.

Attribute Table — Stored information about vector features.

Metadata — Documentation describing how, when, and why a dataset was created.

Datum — Reference model of Earth used for coordinates.
