That is a great looking image Wipneus, where on the ESA site do find them, I can only locate images that are about 1 month old?
Let me describe the typical way I get them.
First a Sentenial data set, product in ESA speak, has an identifier and a name. Both uniquely identify the data, have you got one you can look up the other. In many cases you need them both.
The product name is something like S1A_EW_GRDM_1SDH_20150102T120132_20150102T120202_003992_004CEA_57D0
the corresponding product id
c71daeec-66d5-452e-a198-395a89c936fb
The product name is usually the base for file names used to store the product, it is an (insuficient) description as well. The product id is just a UUID.
Lo-res, jpeg versions of the quicklook images can be seen in the
sentinel data hub, graphical tool where you can do some selections, see some meta-data, see the quick-look image and request for the full (gigabyte) download. Registration (free) is required.
Download of subsection of the data is planned 2015Q2, I think that may include the quicklook images.
Apart from the graphical tool there are programming interfaces (API's) to the data, the Open Data and Open Search. These are described
hereOpen Data works with URL, understandable by your browser and by automatic tools (wget).
For instance with the name and id above, this will download the full (gigabyte) package data set:
https://scihub.esa.int/dhus/odata/v1/Products('c71daeec-66d5-452e-a198-395a89c936fb')/$value
Get the preview quicklook image:
https://scihub.esa.int/dhus/odata/v1/Products('c71daeec-66d5-452e-a198-395a89c936fb')/Nodes('S1A_EW_GRDM_1SDH_20150102T120132_20150102T120202_003992_004CEA_57D0.SAFE')/Nodes('preview')/Nodes('quick-look.png')/$value
Copy the string in the browser and download the image.
The scripts take care of creating these URI's, downloading the result and sometimes interpret the results.
So what I did in this case:
- used the data hub graphical tool to select the correct product. Get the product name (copied from the screen).
- start the odata-demo.sh script
- use option 7: get id from product name
- use option 11: get quick look image from id
This barely scratches what is possible. Downloading ALL quicklook images, given some selection parameters, is already routinely done here.
