EOLI-SA procedure for data ordering Plea find below all the information necessary to u EOLI-SA for ERS, Envisat, ALOS and SPOT products.
草社If your project has been approved for the specific satellite/nsor, you will be able to order:
•ERS SAR archived products and future acquisitions
•Envisat archived products (ASAR HR and GM mode, MERIS FR) and future acquisitions (ASAR HR and MERIS FR)
•SPOT, Kompsat-2, J-ERS, Landsat, Ikonos and IRS archived products
•ALOS archived products and future acquisitions
Procedure
1)If you have to install EOLI-SA, refer to eoli.esa.int/EOLi/EOLi.html
In ca you do not already have the latest version installed, you will be

requested to perform an upgrade upon login.
2) Launch EOLI-SA and u "connect" to login using the urname and password
provided.
Follow the instructions to update EOLI-SA to new versions when applicable.
3) Select from the "on line collections" the mission/nsor/mode of your interest
4) Select a time range
5) Define an area of interest, either by using the input fields or graphically on the
map (in area mode).
The size of the area should be as small as possible but big enough to cover all the area of interest and, in any ca, greater than the standard scene size (ERS SAR, Envisat ASAR IM and AP: 100x100 km; Envisat ASAR WS and GM: 400x400 km; MERIS FR 575x575 km; MERIS FRS: 1150x1150 km).
6) Submit the query.
7) In order to perform an interferometry arch, go into your “local collections” folder where you should have first inrted the relevant on-line collections. Select “interferometry query mode. Select two date ranges and the appropriate values for baline, Doppler centroid and date offt; submit query.
7) Select one or more group results and u "append" or "replace" to visualize the results of the query.
8) Select one or more products from the displayed list and click on the shop cart button (small shop cart icon at the bottom) to add the items to your shop cart. If needed, you can superimpo the thumbnail on the map (drag and drop feature).
9) Go into your "ShopCart" (cond tab in the upper left); lect one or more products (avoid mixing missions, product types, old and new acquisitions) and specify the required order options on the left hand side of the window.
Note that not all products are available via FTP pick-up and when it is available, the product length
might be limited due to constraints in the volume of the file that can be disminated (e important notes below).
描写大海的优美句子In order to define the length of the product required, one product at a time, lect the applicable scene type on the left hand side and u the mou on the map to:
a) drag the scene along the gment (floating scene)
b) resize it (u arrows on either end of the gment) if you lect floating pass
In ca of thumbnail superimposition, if there are discrepancies between the map and the superimpod thumbnail, plea note that the correct values are the coordinates shown in the processing/delivery option area.
Be aware that in ca catalogue data is retrieved using a small arch area (e point 5 above), EOLI-SA will, in the ShopCart folder, try to re-adjust the coordinates for the floating scene specified by the ur in order to fit the lected scene into data gment intercting the ur area. This process may override the coordinates explicitly entered by the ur in the coordinates/frame area at the bottom left part of the ShopCart window"

If the exact same frame is needed, the new item should be shifted back to the position of the original one on the map or using the scene location fields in the order options column.
11) When you have verified all order options, lect with a tick on the left column the items to be inrted in the order and click on "CreateOrder" (gears icon at bottom).
(Note: maximum number of items per order is currently 20, however, for proper media layout, it is recommended not to exceed 5 items for an ERS order)
12) You can then go back and forth between the shop cart window and the order window to check (and correct if necessary) the order items. Check also the shipping information and assign a ur reference. Optionally add a ur remark. If you have veral projects, lect the right one which has the product type allocated and on which you want to place the order.玩趣味
Plea make sure no special character is ud in all fields like address, E-mail, order name and ur remark; u only A-Z and 0-9 characters). If more than one email address is inrted, the strings should only be parated by a comma without any empty space.
13) Submit the order (note: when successfully ordered, items are automatically removed from your shopcart).
14) The submitted orders and their status can be viewed in the "orders" window. Important notes:
- Access to archived MERIS RR datat:
The MERIS RR datat from mid-2002 to June 2006 has been reprocesd with the latest version of the MERIS operational processor and is available on-line via the MERIS MERCI web interface together with the data acquired since July 2006 after consolidation. The last 2 weeks of acquisitions (NRT procesd data) are instead available from the acquisition stations through the Rolling archive. As a result, MERIS RR ordering is not enabled in EOLI-SA.
- Access to ERS ATSR and ENVISAT AATSR datat:
The ATSR (1995-2001) and AATSR (2002-mid 2007) missions have been reprocesd with the latest version of the AATSR operational processor and data are made available on-line via the (A)ATSR MERCI web interface together with the data acquired since mid-2007, after consolidation. The last 2 weeks of acquisitions (NRT procesd data) are instead available from the acquisition stations through the Rolling archive.
As a result, ATSR and AATSR data ordering are not enabled in EOLI-SA.
- Minimum and maximum product size (floating pass) due to processing constraint, in conds
ERS SAR RAW 15-all
ASAR IM/AP level 0 15-120
ASAR WS level 0 24-120
ASAR WSM level 1 24-120
MERIS FRS level 1 60-196
- Maximum size of floating pass for FTP delivery:
ERS SAR level 0 75 c自动化专业就业方向
ASAR WS level 0 60 cs
ASAR IM, AP level 0 75 cs
ASAR WSM level 1 product 120 cs
MERIS FRS 196 cs
Acquisition minimum size:
ASAR IM, AP: 15 c
ASAR WS: 60 c
MERIS FR: 60 c
- Polarisation
A polarisation lected for archived products will not be taken into account
- Acquisition requests:
If the project has been approved for new acqusitions, the PI can make Envisat acquisition requests only for ASAR IM, WS & AP and MERIS FR, and the following constraints shall be taken into account:
a-ASAR IM, ASAR WS and ASAR AP modes, ASAR Swaths and Polarisations are mutually exclusive
b-ASAR (IM, AP, WS) and MERIS FR cannot be recorded simultaneously outside European stations masks (within Kiruna and Matera masks, it is possible to have simultaneously ASAR and MERIS FR) or outside Artemis coverage.
c-Acquisition requests shall be submitted at least 2 weeks + ( 15 days) before acquisition date

- SPOT
The applicability of the extra-cost for data repatriation in the item details window (double-clicking on the magnifier icon) must be verified before submitting the order. The cost of a scene when the flag is t to yes is €400.
