Hydrological Services ML-1 – Transfer Data
Rainfall data downloaded from equipment in the field should ideally be transferred immediately from temporary media (e.g., USB key) to a folder on the laptop, and should be stored in the SiteMonthDayYear format (e.g., 066e072015).
Rainfall data downloaded via Bluetooth will not have site visit start/stop bucket tips to demarcate beginning and ending of data blocks, so those will have to be created for each site visit.
