Gulf of Mannar Islands need names. Here is Indian Govt. data and under GODL license should be usable on OSM

https://www.forests.tn.gov.in/tnforest/app/webroot/img/document/DATABASE-ON-GULF-OF-MANNAR.pdf

Beripeta should be placed here and Sriharikota should be the name of whole island instead of as a village. The wrong data is sourced from 'Automotive Navigation Data'
