[Qgis-user] adding a simple filled polygon

[Bernd Vogelgesang]

Hi,

from what I understand, you just need to make your new layer editable
(pencil symbol), then you can see the symbol for adding a polygon.

Besides that: Be aware that the original coordinate system of GPS points
is EPSG 4326 (unit degrees), and so is the default CRS for layers in
QGIS. In case you want to do more sophisticated operations later with
your data, you should reproject them to a local metric coordinate
system. Tricky topic for beginners. The toolbox is your friend.

Cheers,

Bernd

Now I read the handbook but it is not very clear. It starts with adding a new shape layer (ok). But then it gets very muddly for me. I tried a tutorial but this is for older versions of QGIS (just as the training manual on the QGIS website) and they talk about "click the add a polygon icon" which isn't to be found.
