Just started using seeyou for the first time. I created some waypoints in seeyou and noticed the altitude shown for some of the waypoints are way off. I double checked the exact same point in Google earth and the difference is about 1000'. This isn't the case for all custom waypoints I made, but it is true for most of them. How are you guys creating accurate waypoints and waypoint altitudes. Kind of crazy that seeyou is so off!

Describing exactly wha you are doing and providing sample data will help you get useful help.

Are you using SeeYou Windows app, SeeYou Mobile or SeeYou cloud?

How exactly are you creating a waypoint and how exactly are you looking at its elevation? If say you are looking at stuff in SeeYou Mobile then it may be you are getting confused with waypoint elevation, arrival height, etc.

Assuming you are using SeeYou Windows app as you move the cursor around you should see the elevation shown in the lower window border next to the cursor latitude and longitude, that changing display gives you an idea of the elevation data resolution. Elevation data is only useful within that resolution, if you are trying to pick super fine resolution elevation features it's not going to work. And pragmatically for anything important people usually hand-edit waypoint files, including elevation if needed.

If your SeeYou is not or has not been connected online I imagine it's possible that SeeYou has not downloaded the elevation data (I assume it's still downloading NASA elevation data, even that is a bit more hidden than it used to be).
