Fluctuations of Heard Island Glaciers 1947-2014
https://cmr.earthdata.nasa.gov/search/concepts/C1278276920-AU_AADC.xmlDescription:Understanding of changes in the extent of the Heard Island glaciers has been derived from comparison of brief journal accounts, photographs and drawings made during the early sealing period and later, as scientists began to explore this remote island, from published reports, photographs, satellite images and eventually mass-balance studies. The fluctuations of these glaciers have previously been discussed by Budd and Stephenson (1970), Allison and Keage (1986), Budd (2000), Ruddell (2006), Donoghue (2009), and Cogley et al (2014). This report examines two newly acquired satellite images from 2012 and 2014. What is unique about these images is that in both cases the images are near cloud free and include the entire island. This is unusual for this mountainous island. These images provide the first chance to complete a full inventory of the island's glaciers over both years (2012 and 2014) from a single point in time. Complete satellite inventories of the island have only previously been attempted in 1988 and 2008 - in each case this required the use images over several years and different sources to capture the entire island. This report also includes an inventory of additional data sets and data resources that have been used to calculate the length and areas of Heard Island glaciers between 1947 and 2014.

SPOT-6 and 7 ESA archive
https://cmr.earthdata.nasa.gov/search/concepts/C1965336951-ESA.xmlDescription:The SPOT 6 and 7 ESA archive is a dataset of SPOT 6 and SPOT 7 products that ESA collected over the years. The dataset regularly grows as ESA collects new SPOT 6 and 7 products. SPOT 6 and 7 Primary and Ortho products can be available in the following modes: Panchromatic image at 1.5m resolution Pansharpened colour image at 1.5m resolution Multispectral image in 4 spectral bands at 6m resolution Bundle (1.5m panchromatic image + 6m multispectral image) Spatial coverage: Check the spatial coverage of the collection on a _$$map$$ https://tpm-ds.eo.esa.int/socat/SPOT6-7 available on the Third Party Missions Dissemination Service. As per ESA policy, very high-resolution imagery of conflict areas cannot be provided.

SPOT-6 to 7 full archive and tasking
https://cmr.earthdata.nasa.gov/search/concepts/C2547572697-ESA.xmlDescription:The SPOT 6 and 7 satellites ensure data continuity with the no longer operational SPOT 5 satellite and provide an archive of very high resolution optical acquisition as well as the possibility to task the satellites for new acquisitions. Following the completion of the SPOT 7 mission in March 2023, new acquisition tasking is only available for the SPOT 6 satellite. The ortho-products are automatically generated by the SPOT 6 and 7 ground segment, based on SRTM database or Reference3D when available. The projection available for SPOT 6 and 7 ortho-products is UTM, datum WGS84. Bands combinations: • Panchromatic: black&white image at 1.5 m resolution • Pansharpened: 3-bands or 4 bands colour image at 1.5 m resolution • Multispectral: 4 bands image at 6m resolution • Bundle: 1.5 m panchromatic image and 6 m multispectral image, co-registered. Geometric processing levels: • Primary: The Primary product is the processing level closest to the natural image acquired by the sensor. This product restores perfect collection conditions: the sensor is placed in rectilinear geometry, and the image is clear of all radiometric distortion. • Ortho: The Ortho product is a georeferenced image in Earth geometry, corrected from acquisition and terrain off-nadir effects. Available in MONO acquisition mode only. Acquisition modes: • Mono • Stereo • Tristero To complement the traditional and fully customised ordering and download of selected SPOT, Pleiades or Pleiades Neo images in a variety of data formats, you can also subscribe to the OneAtlas Living Library package where the entire OneAtlas optical archive of ortho images is updated on a daily basis and made available for streaming or download. The Living Library consist of • less-than-18-months-old imagery • a curation of SPOT images with no cloud cover and less than 30° incidence angle • Pléiades images acquired worldwide with maximum 15% cloud cover and 30° Incidence Angle • Pléiades Neo premium imagery selection with 2% cloud cover and 30° incidence angle These are the available subscription packages (to be consumed withing one year from the activation) OneAtlas Living Library subscription package 1: up to 230 km2 Pleiades Neo or 430 km2 Pleiades or 1.500 km2 SPOT in download, up to 500 km2 Pleiades Neo or 2.000 km2 Pleiades or 7.500 km2 SPOT in streaming OneAtlas Living Library subscription package 2: up to 654 km2 Pleiades Neo or 1.214 km2 Pleiades or 4.250 km2 SPOT in download, up to 1417 km2 Pleiades Neo or 5.666 km2 Pleiades or 21.250 km2 SPOT in streaming OneAtlas Living Library subscription package 3: up to 1.161 km2 Pleiades Neo or 2.156 km2 Pleiades or 7.545 km2 SPOT in download, up to 2.515 km2 Pleiades Neo or 10.060 km2 Pleiades or 37.723 km2 SPOT in streaming As per ESA policy, very high-resolution imagery of conflict areas cannot be provided.
