I have world oceans vector layer in .shp format.
It looks like this.
This vector has only one feature, which represents world ocean.
I need to create raster mask with 1 - ocean, and 0 - land.
When I try Rasterize, as output I have fully black raster image.
Then I have tried to create new numeric field
and use this field for rasterizing, but QGIS doesn`t see this new field.
How can I solve my problem?
