they need to resurvey Cozumel for Street View, since those images are getting pretty old
As I explained earlier, the Google street view of Cozumel is a mashup; a cut-and-paste job of many different runs they have made while taking pictures on the island. It s a time machine video that is a melange of images taken on different dates, sometimes years apart, on the same street. To see how this works, just look at the space where the Diamonds International building is on Melgar just south of Restaurante Palmersa. It is not there in this street view, proving it was photographed prior to construction a few years ago. Then, go to the front of Scotiabank on the corner of 2nd street and 5th avenue. The sign in the window states that the date is March 3, 2018. Then, if you go to the Covi on the corner of Av. 30 and 2nd street, you can "toggle" the view by advancing and retreating the viewpoint and it will show different views of Covi taken on different dates. I guess that marks a splice. I am attaching images:
Another time-machine splice of images taken years apart appears at Ave 30 and Rosado Salas, below:
Google was shooting more images a couple of months ago on Cozumel, but I can only assume they will do as they have always done; just splice in some of the new views and leave others as they are. This may have something to do with what one of the past presidentes of Cozumel told me (can't remember if it was Lito or Fredy); Google wants a subsidy from a city to keep the streetview current.
All this just goes to say, DON'T TRUST COZUMEL GOOGLE STREET VIEW! There is no way of telling whether the image you are looking at is ten years old or more and what parts are recent; they are all mash-ups.
And, you are 100% correct. ANYBODY can add anything to Google maps. Just like Wikipedia, Google makes no checks to see if the data added by a member of the public is correct or wildly incorrect. If enough people complain about a data point, they may change it. However, they also may just leave it incorrectly tagged and it is the viewer's tough luck.
