Data set

A data set is a collection of data related to each other. Data in Pangaea are grouped in predefined data sets equal the file uploaded to the system and provided by PangaVista (or other clients or web services) for download. The granularity of a data set depends on the type of data, the number of data points and is primarily in the decision of the data provider. A data set may contain one to many data series, one to many data sets may be grouped to a parent set. Access rights can be defined for a complete set only. Each data set consists of the data accompanied by metadata according to ISO standard fields for describing geodata.

Opening a data set will show four tabs named Config, Basics, Details and Web with metadata fields as described below:

Config tab
 * Parameter window shows parameters with unit and short name, used in the data set. The buttons Add, Clear and PreSelect are used to compose new data sets.
 * Geocodes window lists all geocodes available; those used in the data set are highlighted and can be added to the Configuration.
 * Related metainformation window contains fields from the event table which can be added to the Configuration.
 * Configuration window lists geocodes, related metainformation and all parameters used in the order of the available data set. The Load and Save button can be used to save a configuration and load the same configuration to other similar data sets.
 * Format will show the number of digits before and after the decimal point of a numeric parameter if selected in the configuration window by a mouse click. Different formats can be selected from the pop-up menue or changed by hand. If the geocode Date/Time is selected, different types of ISO formats can be selected, depending on the required precision.
 * Split by event should not be used anymore.
 * Split by versions must be checked if a parameter occurs more than once.
 * Aggregate function may be used to internaly calculate statistic values - do not use.
