Sea level mapping
I recommend https://www.floodmap.net/pro/ for a global mapping site with adjustable sea level. This is incredibly helpful to me, writing stories set in the future or past when the sea levels were quite a bit higher or lower. One note: my bank debit card flagged this site as suspicious when I tried to pay using the debit card (because it's based in India), so I used a low limit credit card and it went through fine. I've never had anything hinky in the billing. It's only $9/mth and you can download maps you've created. You can also use it for free but you can't access all the functions. It's still quite interesting though! My one complaint is they don't have Antarctica mapped very well and one of the novels in my ICE FREE EARTH series is set there. Fortunately, the location of the current novel-in-progress in the series is covered in exceptional detail. Have fun! (Well, it might not be "fun" if you live too close to current sea level, it might be disturbing. Maybe even enough for you to consider making changes while you still can?) The map is the eastern coastline of North America with 50 meters of sea level rise (Greenland + West Antarctica + some of East Antarctica melted).
