Upgrading to 2.12 only consists of stopping all services, installing the new version, running the install_jobs script and restarting the services as described in Deploying.
No change in METAMID configuration is required for existing sites. However, to enable the new features in 2.12 some additional metadata are required. Also, FIMEX 0.41 or later must be installed, and the executable path set in master_config:
FIMEX_PROGRAM = /usr/bin/fimex
METAMOD 2.12 includes a JavaScript-based timeseries plotting library in the browser.
To enable plotting of timeseries, add the following elements to the XML files (or use the metadata editor):
A list of variables to be plotted for all files, eg:
<metadata name="timeseries">time,sea_ice_extent</metadata>
The first variable will be used as the X axis. The others (up to two) will be plotted on the Y axis.
The OPeNDAP URL to the file:
<metadata name="dataref_OPENDAP">http://thredds.met.no/thredds/dodsC/cryoclim/met.no/sie-mar/sie-mar_osisaf_monthly_mean_sie_mar.nc</metadata>
Optionally plotting can be performed by an external server. To enable this, add the following directive to master_config:
TIMESERIES_URL=http://ts.example.com/jtimeseries-webservices/thredds/diagram?parameters=[TIMESERIES]&url=[OPENDAP]
The placeholders [TIMESERIES]
and [OPENDAP]
will be replaced with the variables timeseries
and dataref_OPENDAP
respectively.
For transformation, dataref_OPENDAP must be set as in the previous section.
The following parameters are available for subsetting:
Note that in some cases the form fields cannot be populated (or may be incorrect) due to lack of metadata. Transformation is still available, although the user must figure out the values by him/herself.
If Projection info has been set up for the dataset, reprojection should be available. A list of available projections (as specified in fimexProjections XML) will be displayed in the form. This feature is currently experimental.
This is a planned feature for a later release. To enable this your map server will need to support background maps in EPSG:93995 and EPSG:93031 projections. Further projections may be supported in later versions.
