| Low resolution? |
Original source is from a paper and is a low resolution version of some unknown original graph, as shown by this extract of the unseen original copyrighted graph; this is the same low resolution as the original in the source paper. |
| Article | |
|---|---|
| Purpose of use |
Used to show and explain the Draupner wave. The Draupner incident was a historically significant incident and as such the canonical "rogue wave". It was the first verified measurement of a freak wave by a scientific instrument. It is used in the article both to accompany the description of the Draupner incident and to illustrate the phenomenon in a scientifically accurate manner. |
| Replaceable? |
Not replaceable. The Draupner wave occurred once and only one reading of its data exists (that taken at the time). All illustrations showing the wave form are equally going to be copies or reproductions of that same original data. Additionally as a very clear representation of a genuine rare incident there are exceedingly few equivalent graphs from other incidents available for educational purposes or to illustrate the event for an article on the phenomenon, and those would be very likely to be based upon a copyright representation as well. |
| Article | |
|---|---|
| Purpose of use |
Used to show and explain the first ever verified freak wave by a scientific instrument. In a wider sense it is also used to show and illustrate the topic of the article which (due to extreme rarity) has exceedingly few other illustrative sources of any scientific reliability. |
| Replaceable? |
Not likely to be replaceable. The Draupner wave as the canonical rogue wave occurred once and only one reading of its data exists (that taken at the time). All illustrations showing the wave form are equally going to be copies or reproductions of that same original data. Additionally as a very clear representation of a genuine rare incident there are exceedingly few equivalent graphs from other incidents available for educational purposes or to illustrate the phenomenon to which the article relates, and those would be very likely to be based upon a copyright representation as well. |

Used to show and explain the Draupner wave. The Draupner incident was a historically significant incident and as such the canonical "rogue wave". It was the first verified measurement of a freak wave by a scientific instrument. It is used in the article to illustrate the Draupner wave. Because the article is on the wave itself, neither a close-up of the wave (in isolation from its wave train nor the wave train without a close-up of the specific wave, are sufficient to explain the phenomenon and event, or allow full educational understanding. The image is therefore not redundant to the close-up also provided. |
