Isochrone vs Radius: Which Catchment Fits?
Compare travel-time isochrones and distance-radius maps, including when each catchment is useful and where each can mislead.

How Accurate Is a Drive-Time Map?
Understand what shapes a drive-time map, why it is not a live-traffic forecast, and how to validate a catchment before using it in a decision.

How Population Inside a Polygon Is Estimated
See how Horizon Mapper combines a selected polygon with population and demographic rasters, and why resolution and precision still matter.

Why it matters
A good map should show why, not only where.
Start from the field decision, then choose the geography and scoring inputs.
Read demand, supply, access friction, and confidence together before acting.
