Thats not ludia’s fault but Google maps. Google maps is not accurate enough to implement such event features because a lot of parks are missing which google maps did not take in. Even submitting your own legitimate parks areas doesn’t work properly; tried to add 2 but both got declined.
I highly suggest ludia to take a look at openstreetmap. This is far more accurate and contains various amounts of terrain which can include special terrain dinosaurs, for example (forest, farm land,… You name it). Pogo also used to utilise google maps; but changed to openstreetmap afterwards which imo is stunning and far more detailed than before. Check out openstreetmap.org to see it for yourself. Now it isn’t always better; certain are are still not having enough parks (or other terrains) but thats where we and / or ludia can come in. Create your own ‘map tool’ so players can submit missing areas, for example. Exactly the concept of openstreet but just for this game.
In-game example; google maps -> opensteeetmap
