data_ingestion/alos/alos_forest_extent_download_merge
Downloads Advanced Land Observing Satellite (ALOS) forest/non-forest classification map and merges it into a single raster. The workflow lists the ALOS forest/non-forest classification products that intersect with the input geometry and time range (available range 2015-2020), and downloads the filtered products. The workflow processes the downloaded products and merge them into a single raster.
Sources
user_input: Geometry of interest for which to download the ALOS forest/non-forest classification map.
Sinks
merged_raster: ALOS forest/non-forest classification products converted to raster and merged.
categorical_raster: ALOS forest/non-forest classification products that intersect with the input geometry & time range.
Parameters
pc_key: Planetary computer API key.
Tasks
alos_forest_extent_download: Downloads Advanced Land Observing Satellite (ALOS) forest/non-forest classification map.
group_rasters_by_time: This op groups rasters in time according to ‘criterion’.
merge: Merges rasters in a sequence to a single raster.
