For QGIS 3.14 I was following the tutorials, and I got stuck in adding my very first new vector layer.

Every time I tried to do the option new Vector Layer, no map appears and the the attribute table is empty. I tried using other shapefiles, the same thing happens, no map and no attributes. I have also tried using older versions but none works.

What do I do wrong?

    In that case, it will of course be empty because you haven't created any spatial or attribute data. If you were trying to add an existing layer that contains spatial and attribute to QGIS, you have likely overwritten it and destroyed the existing data. Like saving an blank new Word document over an existing Word doc.

  • i wanted to open this shapefile exercise_data/epsg4326/roads.shp like in the tutorials. And it says I should be able to see a lot of lines, symbolizing roads. But its empty.

  • Thank you @user2856. I think that might be the case because when I opened a shapefile it says "The layer already exists, Are you sure you want to overwrite the existing file?". I must have skipped a step. I'll go over it again.

You have created a new (empty) layer instead of opening an existing layer.

As a file with the same name as the new empty layer already existed, you would have seen a message "The layer already exists, Are you sure you want to overwrite the existing file?". Since you clicked "yes"/"ok", you have saved your newly created empty layer over the existing layer that contained data and destroyed it.

Next time use

  • Layer -> Add Layer -> Add Vector Layer (or various other ways including drag and drop onto the map)

instead of

  • Layer -> Create Layer -> Create New Shapefile Layer

    Or, you may simply drag & drop any file QGIS can read onto the map canvas (e.g. .shp, .gpkg, .json)
