This question came up on the page at the link https://docs.qgis.org/3.16/en/docs/training_manual/vector_analysis/basic_analysis.html.
6.2.5 Try Yourself: Convert Layers’ CRS Item 6. Change the [CRS] to WGS 84 / UTM zone 34S
In the Save Vector Layer as … dialog box, the fourth text box down shows
CRS EPSG:32734 - WGS 84 / UTM zone 34S
This doesn’t match any of the three choices in the dropdown menu. The second choice is
EPSG:32700 - WGS 84 / UTM (southern hemisphere)
This CRS also appears in the list of Predefined Coordinate Reference Systems displayed in another dialog box obtained by clicking on the little ?globe icon to the right of the CRS menu. EPSG:32734 - WGS 84 / UTM zone 34S does not appear in the list.
Why does the instruction not match the choices? Will the choice of EPSG:32700 lead to error, or is this just a simplification of the reference labels?
