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.
