About the Product Navigator
The EUMETSAT Product Navigator is used to search and obtain details about four types of
resources held by EUMETSAT:

Climate: describes a climate product type

Dataset: describes a satellite product type

Document: describes documents available from EUMETSAT

Software: describes software available from EUMETSAT
The following search methods are available to search for the above:

Simple Search: searches for single or multiple keywords (and variations) across all
metadata fields (suitable for general searches)

Extended Search: Using “AND” searches can be conducted across a subset of
given metadata fields (ideal for targeted searches)

Browse by Theme: tree-based access to resources based on themes i.e. satellite,
instrument, category, societal benefit area or dissemination.
All three searches (Simple, Extended and Browse by Theme) are accessible via separate
URLs. You can bookmark your favourite search type as the default start page. The URLs
are:

http://navigator.eumetsat.int/discovery/Start/Explore/Quick.do

http://navigator.eumetsat.int/discovery/Start/Explore/Extended.do

http://navigator.eumetsat.int/discovery/Start/Explore/Thematic.do
Detailed information is available for each of these search methods later in this guide.
The Product Navigator starts by default with the “Simple Search” form. Clicking on the
“Search” button without any text will display all available resources.
Try to be as specific as possible when entering search terms; e.g. MSG wind, GOES South
America fire, or combine two or more terms with quotation marks, e.g. “sea surface temperature”.
Searches can be further targeted by selecting one or more resource type(s) to be searched
(e.g. dataset, document and/or software),

Searching in detail
The Product Navigator offers:

Simple Search: a quick search function that employs fuzzy logic – suitable for
general searches.

Extended Search: a targeted search with the option to filter by multiple metadata
attributes – recommended for users looking for a specific product type.

Browse by Theme: a pre-defined tree navigation of products based on several
themes, including satellite, category (marine, land, etc.), societal benefit area
(disasters, weather etc.) and dissemination types.
In the Extended Search, you can also limit the results to a selected geographical area by
selecting the spatial extent.
Simple Search
The Simple Search function employs fuzzy logic when searching metadata, and can be
made on the basis of a few inputs.
These parameters include:

Climate: a climate product type

Dataset: a satellite product type

Document: documents available from EUMETSAT

Software: software available from EUMETSAT
3
A text input field is used for entering search terms, either individually or in combinations.
The search is by default whole-word based. For example, searching for the term “cea” would
not return the word “ocean”. However, by entering the terms “ocean” or part of the word
between asterisks (*) i.e. “*cea*” the search would be successful.
The following syntax types are available for a Simple Search:

Combined terms (phrases) should be enclosed in quotation marks (“), e.g. "sea
surface temperature"

Wildcards can be inserted for indeterminate characters, e.g. *land, North*, *use*
For best results, try to use multiple search terms; e.g. MSG wind, GOES south America fire –
or combine two or more terms with quotation marks e.g. “sea surface temperature”.
Note that the Simple Search does not distinguish between upper and lower case letters.
Note that Simple Search has an autocomplete. After three characters are entered an
automatic search for matching keywords is made and a list of hits is presented. The list is
amended as further letters are entered:
Extended Search
We recommend that you use the Extended Search whenever possible. With the Extended
Search you can refine your search criteria by choosing subsets of attributes. In general,
filtering using two or more criteria delivers the most accurate results.
4
Extended Search attributes include:
Collection Type
Restrict the resource to be searched:

Climate: describes a climate product type

Dataset: satellite product types

Document: documents available from EUMETSAT

Software: software available from EUMETSAT
One or more entries can be selected by holding down the CTRL key while selecting other
entries with the left mouse button .
Societal Benefit Area
Select one or more benefits if you want to search for a specific societal benefit area.
As shown below one or more entries can be selected by holding down the CTRL key while
selecting other entries with the left mouse button.

Find Data from the EUMETSAT Application Ground Segment (Central Facility and Satellite
Application Facilities).
On the menu to the left-hand side under “Settings”, the “Auto Hit Counter” can be turned on
or off. When activated, you will see the number of hits change as you tick check boxes or
enter search strings.
The setting “EUMETSAT Data” will affect the sort order of the returned results. “EUMETSAT
Data” in ascending order, will first show all resources of EUMETSAT in alphabetic order followed by non-EUMETSAT resources. In descending order non-“EUMETSAT Data is shown
first.
Browse By Theme
When browsing by theme a search is executed based on a tree structure. Selecting a
particular theme will display all resources fulfilling the criteria.
At upper levels of the hierarchy, you can explore the themes’ directories. Once a topic is
selected ( directory or
document), all the entries associated with or subordinate to the
theme will be displayed in a results list.
Common Settings for Searches
Define your settings for sorting search results or the number of hits during query creation.
8
If you want to change the order of the result list displayed, select your preference under
“Search > Settings”.
Modifying the “Auto Hit Counter” will affect only the ‘Extended Search’. Available hits are
dynamically shown (“Number of Records”) when defining or changing query parameters.
This capability is configurable: switch on/off within the “Settings” Dialog. The default setting
is “switched-on”.

) in this view all the details of the product from
Description Tab
The Collection Reference is a unique reference for each product, based on the Product
Provider, data collection type, satellite and acronym.
The Collection Name is the official name of the product.
The Acronym lists the dissemination acronym and archive acronyms of a product (in that
order).
13
The Description is a brief overview of the product.
The Product Status states the dissemination status of the product. States include:
Operational, Pre-operational, Demonstration and Development.
The Date is the date of creation and/or revision of the product.
The Time Range: The “begin” represents the time at which the product was first made
operational. In the case of some older products, the “begin” date is the first date at which the
product was archived. The “end” represents the time at which the product ceased to be
available – even from the Archive. This field is usually left blank.
Geographic Bounding Box: this is a rectangular geographical region within which the
product is available. The default is the whole globe, defined by North-South coordinates = +/90, East-West coordinates = +/- 180 degrees.
Point of Contact: these are the contact details of the originating centre of the data, i.e. the
Product Provider - typically the name of the organisation. EUMETSAT Helpdesk contact
details are also provided.
Categorisation Tab
The Categorisation tab contains some product information relating to search topics and
thematic keywords, such as to which category and societal benefit area the product
corresponds. In addition, you will find information on the satellite and instrument channels (if
applicable), a link to an example image, and links to other available online resources.
14
Distribution Tab
The Distribution Tab contains information about the various product distribution mechanisms. There are various mechanisms such as: EUMETCast, the EUMETSAT Data Centre,
the Global Telecommunication System (GTS), Direct Dissemination and via the Internet etc.
The most complete set of information is displayed for EUMETCast dissemination, including
file name examples, file formats, average file sizes and dissemination frequencies.
Selecting the EUMETSAT Data Centre link will automatically open the online ordering Java
Web Start Application and flag the acronym of the product for ease of access to this product.
Any Legal Constraints relating to the access and use of the data are set out after the
dissemination information as follows:
