I'm currently working on a project in QGIS 3.10 . So far, I had somewhat ignored matters pertaining to projections, because things seemed to be going fine. However, I am now beginning to experience some issues. I am not entirely sure how to resolve them, because I suspect I don't fully understand projections in QGIS yet.
The project's CRS is set to EPSG 3857. I have a map with six layers. They are as follows:
The CRS of these layers are:
- Output: EPSG 4326
- Mean coordinates: EPSG 4326
- randstadstedeninfo: EPSG 4326
- studstedeninfo: EPSG 4326
- GADM36_NLD1: EPSG 4326
- Esri Gray (light): EPSG 3857
Apart from the “Output” (the green oval), it looks like I want it to look. I'm not really sure why it looks the way it does though.
How can I change the CRS of these layers in such a way that the Output (the vertical oval green polygon) becomes a nice circle?
When I change the CRS of the Output to EPSG 3857, it (again) goes somewhere else entirely. I'd like the depiction of layers 2 through 6 to remain the same, and change layer 1 in such a way that it fits neatly within the rest of them (as a circle).
