Coordinate Variable Metadata - Unidata/rosetta GitHub Wiki

In the wizard step for variable metadata selection, we ask the user:

"What type of coordinate variable?"

These options are currently controlled in src/main/webapp/frontEndResources/js/SlickGrid/custom/variableSpecification.js We need to make a few adjustments, as outlined below.

Coordinate Variable Types

value	description
timeOnly	Time only (hour, minute, second, and/or millisecond)
dateOnly	Date only (year, month, and/or day)
fullDateTime	Full date and time string
relativeTime	Relative time (e.g. hours since 1970-01-01)
latitude	Latitude
longitude	Longitude
vertical	Vertical coordinate (e.g. height, depth, pressure)

Notes:

1. relativeTime, latitude, longitude, and vertical used to be called reltime, lat, lon, and alt, respectively.

2. If vertical, user must specify the direction of positive (i.e., the direction in which the coordinate values are increasing). The name of this attribute is called "positive", and will have a value of "up" or "down". The prompt could look something like:

   Which direction do the values increase? [Up, Down] (html select)

metadataTypeStructure (from the MPS xml files) mapping:

This is how the value of the html selector (answer to "What type of coordinate variable?") relates to the metadataTypeStructure value found in the MPS xml files:

html selector value	metadataTypeStructure
timeOnly	time
dateOnly	time
fullDateTime	time
relativeTime	time
latitude	lat
longitude	lat
vertical	depth
