# Spectralmeter data overview
- .sig: The data spectralmeter collects, including reflectance
- .jpg: just a RGB image help us recognize which target we were collecting
- field document: We record some information for each observation
- Spectralmeter record ref as 1st observation, so the real target measurement starts from 2
- When downloading the data, the .sig file starts from 00000, ref measurement is not included. i.e. The first target measurement is 0 although it is 2 when using spectralmeter.
