Mark,

I was at the ALA Conference, and because of this I could not reply to your question earlier. I have not worked with the European Space Agency about acquiring high resolution satellite image for research, however, I advised a student a few years ago about requesting high resolution images for his research from the DigitalGlobe Foundation (www.digitalglobefoundation.org<http://www.digitalglobefoundation.org/>) and also I helped him analyze the images. The Digital Globe Foundation person who worked with us was very kind and sent many GB of archive data of the study area to my student. We got all the archive images we had requested. The images were taken from QuickBird, WorldView-3, and GeoEye satellites. It was a fairly easy process.

All the best. Let me know if you have further questions.

Thanks,
-Wangyal

Hi all,



The European Space Agency provides some high resolution (<1 m) imagery from the QuickBird, WorldView and GeoEye satellites. They say they have a “full archive,” which maybe means they have all available date from these missions (?).



There is an application process, where you have to attest that you’re using it for valid scientific research.  On the application page<https://earth.esa.int/web/guest/pi-community/apply-for-data/3rd-party?IFRAME_SRC=%2Fpi%2Fesa%3FdisplayMode%3Dcenter%26sideExpandedNavigationBoxId%3DCat1Access%26cmd%3Daodetail%26topSelectedNavigationNodeId%3DDATA_ACCESS%26targetIFramePage%3D%252Fweb%252Fguest%252Fpi-community%252Fapply-for-data%252F3rd-party%26ts%3D1561144060506%26colorTheme%3D03%26sideNavigationType%3DDATA_ACCESS%26aoid%3D1484>, ESA has a somewhat vague statement:

ESA will support as many high-quality and innovative European and Canadian projects as possible within the quota limit available, therefore only a limited amount of products can be made available to each project. In the frame of ESA cooperation activities, also users outside Europe can be served.



Does anyone have experience with researchers in the USA getting access to this? Do researchers need to be collaborating with European researchers? What does the highlighted sentence mean?



One problem is that the source for these data, Digital Globe, was purchased by another company (Maxar) and I don’t know if the data is now more closely protected.



There is a small subset of these data available for free relating to the 2004 tsunami in the Indian Ocean, but other than that it seems that the data must be purchased from a commercial vendor or else obtained through this ESA program (if that’s still working).



I don’t know of anything with these resolutions (.3 - .6 meters) available from the free USGS interfaces or other US agencies. Is there anything?  The research group here is interested in hopefully early 2010’s 4-band (visible + infrared) and really is interested in a particular small area on Sumatra that had been affected by that 2004 tsunami, but want follow-up imagery from some years later.



Thanks,

Mark
