[api.met.no] Changes to MetAlerts and other news

[api.met.no mailing list]

Dear API users,

some minor changes to existing products, mainly of interest to Norwegian users.


MetAlerts
---------

You might notice some changes in the CAP XML format for the warnings.
Up to now, all the CAP files have contained only one area per info block,
and only one polygon per area element. We have now done some changes in how
we produce the CAP files, and some warnings may contain several polygons
per area element.

This has always been allowed according to the CAP standard, but since it
has not been used in the CAP warnings from  MET Norway up to now, you might
have to do some adjustments to your system.

Note that in case of overlapping polygons, the are covered is the total of 
all the polygons, with not holes. According to the CAP standard, "if 
multiple <polygon>, <circle> or <geocode>  elements are included,
the area described by this <area> block is represented by the union of all
the included elements".


Textforecast 3.0 beta
---------------------

We have also been busy making a new version of the Textforecast product, 
this time in GeoJSON format which many of you have asked for. This means 
that the coordinates are now included in the JSON file, instead of having to 
be looked up separately. You can test it here:

Currently only the land and coast forecasts are included in the beta, sea 
forecasts may follow at a later date.


Other products
--------------

A new version of the Turbulence charts are expected to be released in beta 
on Feb 1 2023. We are also working on a new version of Sunrise, this time in 
native JSON which many of you have asked for. Stay tuned for more updates.


That's all for now, have a merry xmas and a happy new year!
