I'm trying to make a precision topology map in QGIS 3.14 where my map's corners are defined by geographic coords: this means it should have the same range of degrees on top as on the bottom, and same on left as on the right side of map. For example:

enter image description here

I use the UTM coordinate system, U34 zone, EPSG: 32634.

Coords of my corners: Top-left: '549108, 5506822' Top-right: '553523, 5506822' Bottom-left: '549108, 5502204' Bottom-right: '553523, 5502204'

Actually I feel like my map in the print-composer is oriented in this way (red square is my map range):

enter image description here

And my desired output should look like this (along the parallels): enter image description here

  • Are you aware that the spatial extent of geographical degree in km varies with the latitude? Is there a reason you mix degree and an UTM-zone in your map? – Erik Sep 01 '20 at 12:53
  • @Erik should i care about km? if the U34 zone is from 21ºE to 27ºE there is always 6º of range. if my map got (i.g. 3º of length) there would be always 2 sheets per zone. Am i wrong?

    I use UTM to visualize some values on out-of-bounds description, like kilometers net etc. maybe i should use different coord system to visualize my map properly?

  • Okay, since you only "have a feeling", I suggest your actually have a look at the coordinates of your corners. Use this answer as a guide, and add the actual coordinates to your question. – Erik Sep 01 '20 at 13:13

    okay, i just updated coords. but how does it help me? – Daniel Sobolewski Sep 01 '20 at 13:38
  • This shows that a) your feeling is wrong, the map is perfectly aligned with the borders of the UTM zone/aligned north, b) your map extent is definitely not 2.3° wide both at top and bottom and c) you can't confirm that your corner coordinates are as you intend them to be. – Erik Sep 01 '20 at 13:50
  • b) it was just example, but... what should i do to have a map with 2'30" width and 3'45" length and scale 1:10000? and also i need to display coords of corners in DMS. it should look like: Top-left: '50°02' 30"N, 21°00' 00" E' Top-right: '50°02' 30"N, 21°03' 45" E' Bottom-left: '50°00' 00"N, 21°00' 00" E ' Bottom-right: '50°00' 00"N, 21°03' 45" E' – Daniel Sobolewski Sep 01 '20 at 14:10
  • If you want to align the map with EPSG4326, you need to set its CRS accordingly (properties of your map element in the composer) - but this will lead to distortion. In the same dialogue you may set the extent and scale of your map. – Erik Sep 01 '20 at 14:25
