What is the Axis Order in GeoTIFF?
The axis order of a coordinate system is used to interprete coordinates. For instance should (-5,45) in EPSG:4326 be interpreted as -5 degrees longitude, and 45 degrees latitude or -5 degrees latitude and 45 degrees longitude? The GeoTIFF specification does not appear to specifically address axis order. The EPSG dataset does define axis order for each coordinate system. Unfortunately for most (all?) geographic coordinate systems it defines a lat/long order that conflicts with common GIS practice and the examples and existing practice in GeoTIFF files. For that reason, it is suggested that geographic coordinate systems in GeoTIFF be assumed to be with longitude, latitude coordinate ordering in the GEOTIEPOINTS and related fields. For projected coordinate system the situation is less clear. Examples are all easting, northing but then most projected coordinate systems are defined this way in EPSG. However, a few coordinate system (such as Krovak – EPSG:2065) actually use other axis orient
