The U-MARF User Services Interface (USI)

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


Loading the U-MARF client-side application …


Click here to start


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


A dynamic progress bar appears while the client-side application is launched.


The Java client application is ready for your input.


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


This is the on-line help tool.


Possible to browse help tree and obtain help and definitions for particular features and functions


Back to the real U-MARF on-line interface with

Registration and login …


Generate a personal account using the Register button


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

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


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.


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.


Click ok to return to the Java application.


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.


Also possible to have registered using this button


Fill in user identification and password and click “OK”


Java application navigation …


Left hand area used for definition and management of a query.


Right hand area for the display of results.

For example, the results of a query …


Product location displayed on a map.

Results table of products matching query.


Additional map functions also used for searches (more later …)


Tabs for the selection of different services associated with product query and ordering


Login/logout, account management, information and other ancillary functions


Tab for searching for products (Query) and selecting items for an Order


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) …


Query Mode

Simple Mode: provides a basic set of search parameters.

Product

Time

Space

Quality


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.


These tools control the presentation of the product search tree

Tree Management


Three options:

1. Expand/Collapse tree nodes

Tree Management


Three options:

2. Show only selected nodes.


Three options:

3. Clear selected nodes.


This drop down menu changes the tree hierarchy.


This drop down menu changes the tree hierarchy.

Here the leaves are product types


Changing the option


In this hierarchy the satellites are at the leaves.


Time to make a query …


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)


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.


The number of results matching the query are returned. Click “Yes” to display the results.


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).


The example query here only produced seven results … click “Yes”


Product footprints automatically displayed on the map

List of products found printed in the Results Table


The corresponding footprint is highlighted on the map.

Click on a row to highlight a product.


Select all table rows.

Results Table manipulation buttons.


Shift & Mouse Click will select a block of results-


Control & Mouse Click will select or deselect individual items


This button inverts the current selection.


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


Browse image of the product where available (note for AVHRR this is projected on a map)


Detailed listing of the product metadata


This button will turn on a thumbnail image for each selected product.


The shopping trolley button will place all products in a virtual shopping trolley.


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

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


Products can still be removed from the shopping trolley with this button.


Before we proceed with this order, some details on the map functions …


Area selection allows one to draw a region of interest as part of a query directly on the map.


Change view of the map with zoom functions.


Map style (colours, grids, features) may be changed with the Map layers toolbox.


Click here to turn on place names.


Re-centre and re-size view of the world.

Delivery Method


Order Options


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.


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.


Select Media Type

Order here is On Media


Select Compression


Select Format


For some products possible to select only specific bands.


This button will load any available associated auxiliary data.


Click here to turn on spatial sub-setting options.


Subset by time, browse line number or time from ascending node.


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


This is the region you will receive

Click Check Out to proceed.


Summary of order. If you are happy confirm here.


End User Licence Agreement. Clicking OK will agree to the terms.


Take note of the order number.


Click here to see the status of the order


Open the tree and select your item of interest


Here is the order number

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


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


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


Single product returned with footprint on the map.


Click this option and then use the mouse to interactively draw a ROI on the map.


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


The ROI did not match the location of the product … try again.


New ROI

Hit Search


The product is found.


Next select product and place in the shopping trolley.


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.


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


The sub-setting is applied


When an order is ready …


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

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