Datasource panel

Once a datasource is selected, its Datasource panel will open. In map view you can drag and resize the panel to optimise placement when there are several panels open.

The Datasource panel shows metadata associated with the datasource, and enables you to select, share and edit a datasource.

A unique ID that is the identifier used in most of the Datamesh APIs and tools. Click on the copy buton to copy the ID to the clipboard

Description

Each datasource has a human readable name and description. These can be edited without changing the underlying identity of the datasource. Datasource names are used in labels and should be concise but human readable. The datasource description can be loger but is limited to 500 characeters. FOr extended datasource descriptons use the Details link.

Keyword Tags

The keyword tags are a semi-structured set of terms and identifiers that can be attached to a datasources. To add a tag to a datasource, start to type in the box - you can select an existing tag or if none matches, a new tag will created.

Time extent

A time extent associated with the datasource. This can be one of three options:

  1. Fixed start and end time.

  2. Fixed start time, but continually updating.

  3. Fixed start and end time of the datasource, but still considered currently valid.

The last option is to allow datasources to be selected for a particular time range even though the data collection may be historical, but the data could still assumed to be valid. An example would be measured bathymetry.

Variables

The variables that the datasource contains. You can select specific variables using the select drop down, only these variable will be included in a filtered selection.

Additional metadata

Selecting data

  1. The current geofilter

  2. The current timefilter

  3. The selected variables
