Geospatial 2025 May Session

[weilu]

TODOs:

• Add ppt slides to repo
• Fix convex hall pictures
• Add solutions to repo

Suggestions:

• Consider instead of gadm, using WB approved boundaries (if available)
• Consider adding content on using S2 Geometry
• Consider adding the convex hall plot overlay school points with an alpha < 1

# prompt: make the convex hall area plot semitransparent, include the original points

import matplotlib.pyplot as plt

fig, ax = plt.subplots(figsize=(10, 10))

# Plot the convex hull with transparency
schools_diss_gdf['c_hull'].plot(ax=ax, alpha=0.5, color='skyblue')

# Plot the original points on top of the convex hull
schools_gdf.plot(ax=ax, color='red', markersize=10)

plt.show()
