Planning Tools I’ve Used and Tools I Wish We Used Earlier

Land use planning is often perceived as a purely technical or regulatory exercise. In reality, it is a data-heavy, coordination-intensive, and communication-driven discipline. The quality of a plan is not just shaped by policy but also by the tools planners choose and how well they understand them.

1. GIS & Spatial Analysis Tools

In my earlier planning work, QGIS was our primary mapping tool. We used it for:

• Existing land use maps
• Zoning maps
• Suitability and constraint analysis
• Overlaying hazard, infrastructure, and demographic layers

What I didn’t know then — and only realized later — is that QGIS supports Python (PyQGIS).

That means repetitive tasks like:

• Re-classifying land use layers
• Updating maps when barangay boundaries change
• Batch-exporting maps per sector
  could have been automated instead of done manually.

At the time, every update meant redoing steps by hand which is slow, error-prone, and exhausting for the whole mapping team.

Lesson learned: GIS is not just a mapping tool. It can be a data processing engine if…
