Assign the correct UTM zone to a project in QGIS with one click

Anyone who regularly opens a GPS track in QGIS or works on a local map often wants to have the map displayed in the UTM system. To do this, you first had to find out the correct UTM zone and search for it in the corresponding dialogue box. The first plugin I wrote for QGIS does it all with a single click on the UTM button (in the plugin toolbar). It’s called ProjectUTM and is already in the QGIS Python Plugins Repository.
