The filters are grouped in 3 layers:
- A profile: this is the top level grouping - options are Default; Species Distribution Modelling (CSDM); and Data licensed for all uses. The profiles bring together sets of filters that have been validated as useful by our reference groups.
- A category: these are a set of filters that are generally addressing the same area of interest, for example, Scientific name.
- A filter: the individual fields or assertions used to filter records, for example, "habitatMismatch" appearing in the assertions field. This happens when an occurrence records a marine species in a terrestrial location.
To find information on the filter profile, there is an (i) icon next to the profile name. This will pop up a box with a general description of the profile, a section for each category and a table of the filters in each category.
The category descriptions and individual filter details can also be viewed by clicking on the the information (i) icon next to a category of filters on the search results page.
In addition to displaying the filter descriptions, the filter category dialogue allows you to:
- View excluded record
- Expand and edit filters
View excluded records
To help decide whether a filter category is relevant, the records excluded by a filter category can be seen in a new tab by clicking on the View excluded records option on the filter category dialogue.
Note: these records will display on a new browser tab, the data profile will be disabled on this tab and will have an additional section called User selected filters listing the filters used to include records. This is the reverse of how the filters are used in the filter profiles.
Clicking on the View record option next to a record takes you to the record in question so you can get further detail to decide if the record is relevant.
Expand and edit filters
Clicking this option removes the tick next to the filter category and opens a section with the individual filters displayed. You can then toggle the filters on and off separately.
