Hi, there is no need for any personal attacks here. Edits to remove vandalism from the map are not "rude". As your edits are unverifiable and are consistent with common vandalism from Pokémon Go players the previous changeset was reverted. 

A beach has different features/requirements which define it, specifically "stretches of sand at the coast formed by wave action from the ocean", compared to a patch of mud/pebbles/sand the bank of a pond/lake or a certain type of surface. 

I understand you would like some beaches to appear in Wigan, so the next time Niantic update their map you might get access to a specific Pokémon; however, these are not beaches. They are either mistagged or are better defined by either mud or shingle. Please fully educate yourself on the following wiki pages to avoid further reverts on these edits by myself and other mappers who are upholding the integrity of the data in the map.
