What is ASCII Table data?
Table data in Metview is a generic term for row or column oriented ASCII data. Metview's Geopoints format and the CSV (Column Separated Value) can be both regarded as Table data The detailed description of the format can be found on the ASCII Table overview page.
The Table icon
Table files are represented by this icon in the user interface:
Examining Table files contents
The contents of a Table file can be inspected with the Code editor which can be started up from the user interface (right-click examine on the icon). But basically any text editor would be fine for that purpose.
Visualisation
Direct visualisation of ASCII tables is not available in Metview but it is implemented via the Table Visualiser icon. With this icon we can specify the view type and the columns (or rows) to generate the actual plot. Visualisation is supported both on maps and xy-charts for scalar and vector data, as well.
Conversion between Geopoints and GRIB
A GRIB fields can be directly exported into Geopoints using the Grib To Geopoints icon. The other direction is also possible with the Geopoints To Grib icon, which offers various interpolation techniques to compute the grid point values from the values available at scattered locations.
Script language support
Metview provides full support for ASCII Tables from its Macro and Python interfaces.
The list of available functions for ASCII Tables can be found on theTable Functions page.
