column type/group | column order | column header | value is mandatory | description | example values |
---|---|---|---|---|---|
spatio-temporal location | 1 | date_time_start | yes | Date and time of measurement in ISO 8601 format notation, using UTC time zone, without fractions of seconds. Or start of time range. | valid: |
2 | date_time_end | no | End of time range of measurement in ISO 8601 format notation, using UTC time zone, without fractions of seconds. | see above | |
3 | elevation [m] | no | Elevation in meter. A negative value means below sea level, while positive value means above sea level. See Pangaea Geocode definition. Note: This is not the height/depth of the measurement (unless it's taken on earth's surface) but the topographical elevation at the lat/lon position. | ||
4 | z_value [m] | no | Vertical position of the measurement, in meter (third spatial dimension). | ||
5 | z_type | yes, ifz_value is given | Pangaea Geocode to describe the type of z_value [m] . | valid: "DEPTH, water" | |
metadata reference | 6 | event_name | yes | Name of event. Reference key for metadata. event_name must match one event name in metadata file (if metadata file is used). | PS1010-1 |
data | <parameter> [<unit>] | no | Arbitrary amount of columns (at least one) with (measurement) data. Each column name has to start with the parameter/phenomenon name followed by a unit in square brackets. Reference key for metadata. | ||
spatio-temporal location | last | geometry | yes | Geometry in WKT notation without third spatial dimension. The reference system needs to be EPSG:4326 and the unit is decimal degrees. Longitude comes first, latitude second. The geometry type can be chosen freely. However, a simple POINT is usually the best choice. |
