WESM.gpkg coordinate ordering changed! #29

Open scottyhq opened 4 days ago

scottyhq commented 4 days ago

Very strange, but sometime recently, the coordinate ordering in the USGS WESM.gpkg changed, causing our search and tests to fail 🤦 : 

ogrinfo -so -al /vsicurl/https://prd-tnm.s3.amazonaws.com/StagedProducts/Elevation/metadata/WESM.gpkg | grep Extent
#Extent: (13.232000, -179.250067) - (71.507000, 179.854651)
ogrinfo -so -al WESM.gpkg | grep Extent            
#Extent: (-179.250067, 13.232000) - (179.854651, 71.507000)

(maybe last update on 2024-11-24T06:33:34.000Z according to https://prd-tnm.s3.amazonaws.com/index.html?prefix=StagedProducts/Elevation/metadata/)

I'll setup a workflow to run tests nightly to keep track better track of these sorts of changes... Also sent an email to USGS.

Good catch! Did the crs and axis order definition change? Are we loading that directly, or assuming 4326?

No, unchanged from https://epsg.io/4269 (with Data axis to CRS axis mapping: 2,1). But the coordinates themselves have all changed from (lon, lat) to (lat, lon). So opening WESM.gpkg in QGIS now looks like this :)
