"The issue is there is so little research on water levels"
That's just not true. Here's one of many graphs on water levels on a global scale: https://commons.wikimedia.org/wiki/File:Post-Glacial_Sea_Lev... . By 7K years ago the major sea level rise was nearly finished. For example, the Persian Gulf was flooded about 8,000 years ago.
You imply there is insufficient information on global water rise. A quick search finds this a study on the "Late glacial to post glacial sea levels in the Western Indian Ocean" http://www.researchgate.net/publication/40702427_Late_glacia... . It describes some of the many other studies in sea level rise that were done in places other than the US coasts.
"Keep hoping that someone will build some drones that can just fly around and measure this stuff"
If you read the paper you'll see the aerial photography is not enough. The research also included drilling and submersible dives.

Extensive research has been done in part because of how it's coupled to projections of future sea level rise: https://en.wikipedia.org/wiki/Sea_level_rise .
