Description
I will never know if changing the CRS will work or not in QGIS, for over 2 years, each time that i got a project where i have to change the CRS, i know that i will have a headache.
It either works, or it will never work. this are the only 2 versions that i found
I had made a video illustrating such a case http://youtu.be/4DGwXTQStNU
Please tell me what i don`t do right.
Maps and mostly electronic maps should be like 0 and 1
Logic things, if i do this that will happen.
With changing the projection of the map, in QGIS, this is a mystery.

- Status changed from Open to Closed
The numbers in your coordinate status bar don't look like to be EPSG:4326.
You are assigning a wrong CRS to your layer.

I know, and i want to change the CRS of my layer to be 4326
From what i remember QGIS have this function , but i am not able to find it / use it ... ?

Updated by baditaflorin - about 9 years ago
From what i understand from you, the file is in different projection from the start. If that is the case, and QGIS does not recognize the initial projection, me, as the user, i should be noticed about this. If not this leads to awkward situation when i do something, QGIS says that it did what i wanted, but nothing is working , and this is not the expected behavior

- Priority changed from Normal to Low
- Status changed from Reopened to Rejected
- File unkown_projection.jpg added
There is already an option in QGIS which prompts users to define the layers with unkown projections. You need to activate that as your default (Settings > Options > CRS ...see attached).
For poejection on-the-fly transformation to work (and hence the openlayers plugin), it is essential to have all layers make their correct CRS known to QGIS.
If you still have problems with that, please refer to QGIS manual and user mailing list.
