Boundary polygon with point labels.
Legend/layer panel showing the classification scheme.

Discussion

The workflow demonstrates that survey-coordinate data can be organized in a spreadsheet and converted into a clear digital map without manually placing every point. Separate layers improve readability and make control, boundary, and site features distinguishable. The coordinate source and reference system must always be documented because plotting coordinates does not itself establish their accuracy.

Conclusion

The nine-point dataset was organized, imported, classified, and mapped using Google Sheets and My Maps. The final digital map separates survey control, boundary geometry, site features, and access information into readable layers suitable for introductory GIS/mapping work.

Submission: Handwritten RW due on the next meeting with the required printed digital-map evidence.
