Why is replacing broad ZIP-code zones with pixel-level mapping more effective for delivery coverage?
Using pixel-perfect mapping dividing delivery areas into hexagonal grid “tiles” instead of broad ZIP zones gives Walmart much finer control over routes. Each hexagon is packed with real-time data (drive times, store capacity, demand), allowing smarter coverage. This method fills the gaps left by ZIP code-based mapping and lets stores tailor delivery zones accurately, expanding reach and improving customer service.
