Auto-select suitable UTM Zone based on Grid Intersection

There's the utm package, a bidirectional UTM-WGS84 converter for python. It's able to convert a (latitude, longitude) tuple into an UTM coordinate: import utm utm.from_latlon(51.2, 7.5) >>> (...

Why does the same UTM northing give different values when converted to latitude?

This is perfectly normal behaviour in a transverse Mercator projection. The fact that a specific northing does not match a specific latitude (except for the Equator itself) can be easily visualized. ...

Which projection is this data in?

Obviously the data is in UTM32 including the number of the zone. You can strip the 32 in front of your x-coord away as it is explicitely given by the provided CRS. However QGIS should be able to deal ...

Layer disappears when changing from CRS in degrees to CRS in meters in QGIS

Do not use "Set CRS" within layer properties. This does not reproject your data. You only define the CRS there. Means: you tell QGIS that the layer is in a different CRS than it actually is. ...

R: Return the UTM zone that a WGS84 point belongs to

Each UTM zone is 6 degrees wide, so you can get the zone number by looking at the longitude: floor((longitude + 180) / 6) + 1 This assumes that you have longitude within [-180.0, 180.0).

EPSG code for UTM zone

The latitude band is, strictly speaking, an MGRS thing, not a UTM thing. For UTM, all you need to know is which side of the equator you’re on, so for 29U, you can use EPSG:32629.
