The maps have a daily frequency and a ground resolution of 250 m. They are derived from daily MODIS observations (Aqua and Terra) for the entire Alps arc. The input data are the atmospherically-corrected reflectances of MODIS MOD09GQ, MOD09GA for tile h19v04 and h18v04. The map has two bands - SNOW MAP: Snow cover classification map with four classes [0 = NO DATA - missing or corrupt data of one or more input bands; 1 = SNOW - pixel covered by snow; 2 = NO_SNOW - pixel not covered by snow; 3 = CLOUD - pixel covered by clouds; 4 = OCEAN WATER - pixel over sea and ocean; 5 = INLAND WATER - pixel over lakes and rivers], QUALITY FLAG: Snow cover quality map [NO DATA - missing or corrupt data of one or more input bands; QUALITY_INDEX - higher values indicate higher likeliness of correct classification].","keywords":["SNOW","MODIS","SNOW MAP","ALPS"],"version":"v1","deprecated":false,"license":"CC-BY-4.0","providers":[{"name":"NASA","roles":["producer"],"url":"https://modis.gsfc.nasa.gov/"},{"name":"Notarnicola Claudia","roles":["processor"],"url":"https://www.eurac.edu/en/people/claudia-notarnicola"},{"name":"Alexander Jacob","roles":["processor"],"url":"http://www.eurac.edu/en/people/alexander-jacob"},{"name":"Bartolomeo Ventura","roles":["processor"],"url":"http://www.eurac.edu/en/people/bartolomeo-ventura"},{"name":"Eurac Research","roles":["host"],"url":"http://www.eurac.edu"}],"extent":{"spatial":{"bbox":[[4.216446958373531,42.817152675995985,18.99055634355496,48.601848359993454]]},"temporal":{"interval":[["2002-07-03T12:00:00Z",null]]}},"links":[{"rel":"items","href":"https://stac.eurac.edu/collections/ALPS_SNOW_map_MODIS/items","type":"application/geo+json"},{"rel":"parent","href":"https://stac.eurac.edu/","type":"application/json"},{"rel":"root","href":"https://stac.eurac.edu/","type":"application/json"},{"rel":"self","href":"https://stac.eurac.edu/collections/ALPS_SNOW_map_MODIS","type":"application/json"},{"rel":"items","href":"https://stac.eurac.edu/collections/ALPS_SNOW_map_MODIS/items","type":"application/geo+json"},{"rel":"licence","href":"https://creativecommons.org/licenses/by/4.0/","type":"text/html","title":"License Link"},{"rel":"http://www.opengis.net/def/rel/ogc/1.0/queryables","href":"https://stac.eurac.edu/collections/ALPS_SNOW_map_MODIS/queryables","type":"application/schema+json","title":"Queryables"},{"rel":"http://www.opengis.net/def/rel/ogc/1.0/queryables","href":"https://stac.eurac.edu/collections/ALPS_SNOW_map_MODIS/queryables","type":"application/schema+json","title":"Queryables"}],"cube:dimensions":{"x":{"type":"spatial","axis":"x","extent":[4.216446958373531,18.99055634355496],"reference_system":3035},"y":{"type":"spatial","axis":"y","extent":[42.817152675995985,48.601848359993454],"reference_system":3035},"t":{"type":"temporal","extent":["2002-07-03T12:00:00Z",null],"step":"P1D"},"bands":{"type":"bands","values":["Snow_cover_classification_map"," Snow_cover_quality_map"]}},"summaries":{"eo:bands":[{"name":"Snow_cover_classification_map","common_name":"Snow_cover_classification_map","center_wavelength":"N/A"}],"platform":["Aqua, Terra"],"instruments":["MODIS"],"constellation":["Aqua, Terra"],"eo:cloud cover":{"max":9999,"min":9999}},"assets":{},"sci:citation":"Notarnicola, Claudia, Martial Duguay, Nico Moelg, Thomas Schellenberger, Anke Tetzlaff, Roberto Monsorno, Armin Costa, Christian Steurer, and Marc Zebisch. 2013.
