How to create a line from CSV coordinates?

The first step is to open the data in a text editor (like Notepad) and replace the semicolons with commas (edit>replace, or ctrl-h). That gives you a group of items (with internal spaces), separated by commas, as below: Note that I am only using points that you have listed as “Row 1” for this example.

What kind of shapefile is compatible with QGIS?

For the same reason, if you create a new shapefile with QGIS, two different projection files are created: a .prj file with limited projection parameters, compatible with ESRI software, and a .qpj file, providing the complete parameters of the used CRS. Whenever QGIS finds a .qpj file, it will be used instead of the .prj.

What kind of encoding does QGIS use for CSV?

Currently QGIS imports CSV as UTF-8 Encoding. If you are using ANY OTHER encoding, create TWO tables: one for the LAT LONG import, and one to join the other character set attributes to the resulting points layer (see JOINS for details on how to accomplish the second JOIN process). 6.

How to convert tabular data to points in QGIS?

With the correct CRS selected, hit Okay, and the points should appear as a new data layer in the QGIS Layer List and the Map View. 1. The imported x, y values will now be converted to point features (in WGS84 coordinate system) 2. Right-click on the layer to Open the Attribute Table, and make sure the tabular data was imported 3.
