 mwrepjson ( python ) wrepjson (   magjson/magjson )


For the needs of ecCharts and the epsgraph module, Magics   allows the use of Metview Geopoints files.

Geopoints is the format used by Metview to handle spatially irregular data (e.g. observations) in a non-BUFR format.

The Format is an ascii format.

can load input data  formatted in a specific WrepJSon format.

In future releases, Magics will accept more generic format.

 Magics only lets you display Geopoints values as symbols or vectors. If you are interested in contouring irrregular grid values such as Geopoints are, you should first interpolate these values into a regular grid before plotting with Magics. More information can be found in the Metview documentation.
