I wonder why some .csv files when imported (with long and lat) can not set a proper CRS system and other do (CRS undefined). For example:
- If I export my data in csv with Microsoft Excel it does not set the CRS and can not be fixed.
- when I export with Google Sheets it does work.
What is the problem in this case? I am trying to export data with pandas python but can not figure out this problem? I am using QGIS, 2.12.1-Lyon, on MAC.
