WLOC

Use cases

How can map SDK teams verify coordinate conversion issues?

Map SDK location errors often come from coordinate-system mismatch, not GPS. WGS84, GCJ-02, BD-09, provider links, and app-side transforms can put the same landmark hundreds of meters apart. Compare Pick landmarks where offset is obvious.,…

Problem

Map SDK location errors often come from coordinate-system mismatch, not GPS. WGS84, GCJ-02, BD-09, provider links, and app-side transforms can put the same landmark hundreds of meters apart. Compare Pick landmarks where offset is obvious., Compare coordinate-system output., Add offset samples to regression tests..

Solution

SDK teams using WLOC keep the link, normalized coordinate, conversion result, and target-app display together. That makes it easier to compare basemap position, API output, and in-app pin behavior. Check Pick landmarks where offset is obvious., Use plazas, bridges, park gates, campus entrances, or other visually identifiable places., Add offset samples to regression tests., Save links, coordinates, screenshots, and diagnostics so future releases can catch conversion regressions..

Use WLOC in 3 steps

  1. 1Pick landmarks where offset is obvious.Use plazas, bridges, park gates, campus entrances, or other visually identifiable places.
  2. 2Compare coordinate-system output.Check WGS84, GCJ-02, BD-09, map link parsing, and target-app pin placement side by side.
  3. 3Add offset samples to regression tests.Save links, coordinates, screenshots, and diagnostics so future releases can catch conversion regressions.

Important boundary

WLOC is not a jailbreak. It does not install system certificates. It does not include a VPN. And it does not promise to override every app's permissions, cache, or anti-cheat checks.
