If my layer extent is > -360 and < 360 am I really crossing 360? I’m crossing 0 from negative values to positive values. Is that the same?
Also, regarding not being able to save the layer I created with densification, when I try to close QGIS it says I have a ’scratch’ layer that will be lost, which would be this layer created by densification. How do you save a scratch layer?
