Is there any indicator of https://legacy.iho.int/mtg_docs/com_wg/NCWG/NCWG2/NCWG2-08.9A%20seagrass.pdf image being freely licensed? Mateusz Konieczny (talk) 03:35, 22 March 2024 (UTC)

Thanks for the careful remark. Effectively the https://wiki.openstreetmap.org/wiki/File%3ASEAGRA18.svg symbol is a new svg symbol creation by myself as OSM contributer. It is following the idea of a Spanish proposal for use and benefit of a seagrass symbol provided with the suggestion for its international use in seamaps by following text: "Spain recommends the adoption of a new symbol for Seagrass, different to Seaweed, ... , and its inclusion in S4/INT-1. This new distribution of vegetation in INT1 and S-4 could be:" This is followed by a more detailed example for a seagrass symbol. So while the symbol used in OSM and reference here ( https://wiki.openstreetmap.org/wiki/File%3ASEAGRA18.svg ) is not the same, I additionally see a clear endorsement by the Spanish delegation of their idea recommanding the international use of their or similar symbols for seagrass in nautical charts.

Nevertheless, in the wiki explanation on seagrass I also placed more close b/w representations of the detailed symbol from https://legacy.iho.int/mtg_docs/com_wg/NCWG/NCWG2/NCWG2-08.9A%20seagrass.pdf. Following your questions here, it makes sense to remove the two detailed b/w symbols from the OSM wiki and only stay with the link to the pdf document, which contains a detailed raster symbol for seagrass provided by Spainish delegates. I will do so shortly.

All remaining seagrass symbols (the green ones in the wiki) were created by myself and by a contributor of the opennauticalchart from the new svg symbol, intended for use in the OSM context.
