I have completed the OCEAN01 tutorial using the Gulf_of_Trieste_seamaks_UTM33.shp file. I have replaced this shapefile with a world_shorelines.shp file since I need to process other areas of the world. I had to invert the shape file since it was originally masking the water. I noticed that the mask was close to the edge of land so I used “Extend shoreline by Pixels” and this did not affect my results.
Question: Should the “Use Vector as Mask” and “Extend Shoreline by Pixels” both work together without problems? I did a very large pixel offset set of 100,000,000 and I did not see any change in my results compared with pixel offset of 10 when I had to use invert vector. Any suggestions?
