Add estimated elevation field in sarvey_export output

[mahmud1]

It would be helpful to include an estimated elevation field in sarvey_export. This field would provide an estimate of the elevation based on dem+dem_error+offset. Offset is geoid height and can be incorporated as an additional argument.
What do you think @Andreas-Piter?

[Andreas-Piter]

Yes, sounds good. The correct elevation should be computed anyway (#16 ), and I agree, we could add offset as argument.

Dear @Andreas-Piter,

I hope you are doing well.

I was looking into the issue of elevation estimation and had a question: Is the DEM error generated by SARvey in the LOS direction? If so, would it be necessary to convert it to altitude in order to sum it with the other components (DEM and offset)?

Dear @yurioliveira-ctec,
The DEM correction estimated in SARvey is with respect to a reference point. In order to achieve the actual height of the scatterer, an offset w.r.t. the geoid and the DEM height needs to be added.
If you require the height in the output shapefile, you can manually compute the value as described above by Mahmud above. We will add this soon to the software.
