The U-MARF User Services Interface (USI)

A Java Web Start Application for On-Line Access to the U-MARF

slide4

Read the pop-ups and respond as appropriate. For this presentation all certificates and warnings were accepted (YES).

slide9

Note: this client-side application includes a built in help system, providing context sensitive help whenever you click the help link.

slide14

A simple web-based form for entering user details and creating a login account

All fields marked with an asterisk “*” must be completed

slide16

The default preferences for requested media and geographic region of interests may be specified. These will be applied by default but can be over-ridden for specific orders.

slide18

Some formats only apply to specific product groups.

Note: in ordering data from other product groups your default format may not be applicable and may lead to non-completion of the order. Please be aware of this potential problem. We hope to minimise the occurrence of conflicts with ongoing improvements in error-handling.

slide20

Login Here

NB: for some actions keyboard shortcuts are available, e.g. Alt L for Log in (active characters are underlined) and “tab” keys to change focus. These features may by OS dependent.

slide25

Right hand area for the display of results.

For example, the results of a query …

slide26

Product location displayed on a map.

Results table of products matching query.

slide31

Selection of product group

GEO : Geostationary Satellite Data (e.g. METEOSAT)

LEO : Low Earth Orbit Satellite Data (e.g. METOP)SAF : Satellite Application Facility (High Level Products based on GEO and/or LEO data from the SAFs)

Multimission: All products (i.e. queries across the GEO, LEO and SAF groups)

Auxiliary Data: This is additional data used in the processing of LEO products (e.g. calibration and ephemeris data) …

slide32

Query Mode

Simple Mode: provides a basic set of search parameters.

Product

Time

Space

Quality

slide33

Change Mode

Advanced Mode: provides a more detailed set of search parameters on a per product basis. Non applicable parameters are greyed-out. A single product must be selected.

slide35

Three options:

1. Expand/Collapse tree nodes

Tree Management

slide36

Three options:

2. Show only selected nodes.

slide37

Three options:

3. Clear selected nodes.

slide39

This drop down menu changes the tree hierarchy.

Here the leaves are product types

slide45

Select a group of products

… or only a specific product

Specify a Time range Of Interest (TOI)

Specify a Region Of Interest (ROI)

Click on Search (or hit return on the keyboard)

slide46

For this case a warning occurs indicating that no Region Of Interest (ROI) was selected. Either acknowledge “Yes” or click “No” if you want to specify a ROI.

In general a query has to include a product selection and a Time Range Of Interest. Specifying no ROI will search without geographic restriction. Time range will automatically reset to valid values if inconsistent data is entered.

slide49

Warning: possible to define a query with too many results (e.g. > 500). A request is printed to refine the search (e.g. make the time window smaller).

slide51

Product footprints automatically displayed on the map

List of products found printed in the Results Table

slide52

The corresponding footprint is highlighted on the map.

Click on a row to highlight a product.

slide53

Select all table rows.

Results Table manipulation buttons.

slide57

Selecting an individual item and clicking the magnifying glass button will open the product details page.

slide63

Note: One must be logged in to place items in the trolley.

Red-highlighted icons indicate a product is in the shopping trolley.

slide81

Specific Browse if available.

Note: If product has no browse any available AVHRR browse from the same time interval is displayed.

The browse image can be used to make graphical selection of data to subset.

slide82

List name here includes the sensing start time instrument and system. The U-MARF archives data from all missions and avoids any specific mission conventions.

The EPS native format is self-describing and the original product name can be found in the product header and also in the metadata here.

slide84

Select Media Type

Order here is On Media

slide91

Possible to hold down the mouse and pick up a graphical sub-setter at either end of the image.

slide92

This is the region you will receive

Click Check Out to proceed.

slide98

Here is the order number

This name is the internal generic archive name of the product.

slide99

A query including a Region Of Interest (ROI) and the following behaviour in the shopping trolley …

slide100

A query for a specific MHS 1B product is first performed to aid this demonstration., by making a strict constraint on the time window.

Hit search

slide103

Region of interest indicated by green area.

Corresponding coordinates featured here.

Also possible to enter the co-ordinates directly in the query Region of Interest Text Fields.

Hit Search

slide105

New ROI

Hit Search

slide108

NOTE: This demo is using test data prior to satellite launch .. The browse image is a generic image and does not correspond to the footprint (it will for real data)

In the shopping trolley tab, the product is selected and the browse is displayed.

slide109

Selecting this button will automatically subset the product according to the ROI used in the search

slide112

On a subsequent login a notification of reported orders may appear.

Click “OK” to go direct to the Order Follow Up tab.

slide115

This is an on-line order.

Click here to download the results.

slide123

Direct Order

Product Type and Satellite ID

Enter exact product time, wildcards may be used.

Submit will make the query and place the order. The tab selection switches directly to the order follow up page.

slide127

Direct Order : LEO Example

The query will match the sensing start time.

Internal U-MARF Setting

Set by the Producing Ground Segment

Submit

slide130

Bulk Order: intended for very large data volumes

Specify the properties of the order in the left hand fields. On submission the order will go to a submitted status and an entry appear in the order follow up pages.

Bulk order is a mechanism whereby the user can submit an order which exceeds the normal user quota. The order is processed only after a manual authorisation at EUMETSAT, only then will the status change in the order follow-up.

Tip: first check the parameters of your bulk request are viable by submitting a small volume normal order via “Query and Order”.

slide132

Standing Order: for times in the futures allows one to set up an automatic job to provide a sequence of orders.

Define Specific Query Options …

… and related formatting parameters

slide134

4 days

6 Hours

3 Hours

Query Interval

How do the timings work?
