The most common error I've seen in this area is that most GIS systems use (Lat, Lng) but most systems written by non-GIS people use (Lng, Lat), which they think of as (x, y).
- iudqnolq 6y agoI think you have that backwards? In my very limited experience most GIS systems use ENU ordering (east, north up), and easting corresponds to longitude.
- hurrrrrrrr 6y agoI think he has that correct. Ime it's split on east/north vs. north/east but wgs84 is very dominant with lat/lon.
- iudqnolq 6y agoHuh, thanks. Researching this more, I think you're right. I thought the Open Geospatial Consortium's standards would reflect dominant practice, that turns out to have been the wrong assumption [1] The only geospatial software I've used is Proj4J, which normalizes with a function called toENU. I guess I've only encountered weird stuff then. [1]: https://lists.opengeospatial.org/pipermail/coordtran.wg/2006-December/001877.html https://lists.opengeospatial.org/pipermail/coordtran.wg/2006...
