What exactly is my X5's altitude?

I posed this question on the DJI forum as well…

I spot checked the elevation today and compare to satellite acquired lidar data. I’m way off.

My .jpg data has “Altitude” of 325.034. Image was captured on the ground btw.

Compare that to satellite captured lidar data which is 1334’ ASL.

Using the meters to feet converison of 325.034 x 3.28084 = 1066.384514.

What am I missing here? This has apparently been happening since I’ve had the camera.
