Additional Information
This is an expected behavior. The elevation value stored within the 'Altitude' GNSS metadata field represents the raw Height Above the Ellipsoid (HAE) value whereas the value displayed within the GPS Details displays 'Altitude' in MSL or orthometric height if this value is available from the receiver being used. Therefore, these altitude values would be different in this case. The value written into the Z-value coordinate of the feature geometry will reflect the orthometric height value. Please refer to -https://doc.arcgis.com/en/field-maps/android/help/high-accuracy-data-collection.htm#ESRI_SECTION1_C992B4FE465A4AFAB98A4972E336E808 under the section Supported GPS Metadata. It is stated the Altitude—Ellipsoidal height received from the GPS receiver (not orthometric height, as used for z-values).Steps to Reproduce
