Conventions
Some conventions that have been implemented:
Attribute names are all lower case and word separated by ‘_’
All times are UTC, other time zones are supported but strongly discouraged.
Units should be in SI and when a name is required should be all lower case and spelled out, for example ‘nanotesla’ or ‘millivolts per kilometer’
All azimuth angles should be relative to geographic north and measured positive clockwise in a right-handed coordinate system with z positive downwards.
All angles should be in degrees
Locations are given in latitude and longitude in decimal degrees and should all use the same well known datum. Default is WGS84.
