Description

So 2.9682203345000744 would become 2.97. OSM data precision (~1 cm) does not require nanometer imagery positioning.

Summary: Round imagery offset numbers to 2 decimal digits → [patch] Round imagery offset numbers to 2 decimal digits

Patch is in #5787

There may be problems with non-metric projections such as EPSG:4326. However, 1m precision is still good, I'll probably commit it tomorrow.

Fair point, I've fixed the patch to support it. But Bing layer (and, probably, any other TMS) do not support EPSG:4326. And precision is not 1 m, but around 1 cm.

Strange, for me Bing works well with EPSG:4326.

  1. Add Bing layer in Mercator projection
  2. Zoom to 10 m or less
  3. Apply any offset to Bing layer (just drag it a bit, or type "1;1")
  4. Change projection to WGS84
  5. FAIL

Although it works with no offset or on large zooms.
