Hi Marwan,

you can find several traces as datasets in my publications list. I have several papers on a mixed indoor-outdoor environment with associated datasets. Feel free to contact me for more information. As an example, see publications attached to this post. Critical can be the fact that we never recorded the elevation/altitude since we are doing 2D localization. However, you can simply add the altitude as 2 m yourself to the traces since the UAV, we used to sense and record data, was keeping the altitude constant at  2m. Good luck.
