Introduction

The o2a.GeoCSV Format extends the NRT Data Format with a geometry column. It creates the possibilty to describe both, simple and complex geometries for visualisation products.

o2a.GeoCSV Format version 1

Definition for Format version 1 is in progress and is not yet proofed. It is basically a GeoCSV using the WKT notation.

o2a.GeoCSV Example

datetime    vessel:polarstern:mins:latitude [deg]  vessel:polarstern:mins:longitude [deg]  vessel:polarstern:tsk1:salinity [psu]  vessel:polarstern:geometry [point]
2019-02-28 15:50:00.000  34.03449  -14.17956  34.1234  POINT(34.03449 -14.17956)
2019-02-28 15:50:01.000  34.03449  -14.17956  34.1345  POINT(34.03449 -14.17956)
2019-02-28 15:50:02.000  34.03449  -14.17956  34.1456  POINT(34.03449 -14.17956)

Format

A tab seperated file based on specifications of the NRT Data Format extended with a geometry column based on the WKT geometry specification. The coordinates in the geometry column must be in decimal degreee in EPSG:4326.

For complete description of the NRT Data Format see 'Format' in NRT Data Format Version 2.


Geometry Header - Units

The 'unit' in square brackets '[ ]' is used for describing the geometry type. If empty 'point' is the default. If no 'datetime' the row will be deleted.

datetime    type:dev:longitude [deg]    type:dev:latitude [deg] type:dev:parameter1 [°C] type:dev:geometry [point]

datetime    type:dev:parameter1 [°C]    type:dev:geometry [line]

datetime    type:dev:parameter1 [°C]    type:dev:geometry [polygon]
