DWH Core services of some use RapidEye/Blackbridge and SPOT from catalogue available??
GSC downstream services Biopar too coarse, synthesized or not for these areas
ESA missions contributing to Copernicus Sentinel 1a Sentinel 2 when available
Third Party Missions contributing to Copernicus RapidEye/Blackbridge, SPOT, WV2 in ESA/Copernicus archive; obtain through DWH or ESA proposal?
