MODIS optical data with daily revisit rate fetched using Global Imagery Browse Services (GIBS).
MODIS (GeoTIFF) provides many different layers of MODIS TERRA data based on the Global Imagery Browse Services (GIBS) from NASA. The block is different than most other data blocks. MODIS data is provided as a global daily coverage, separate scenes are not considered. This means that all geometric filters have essentially the same functionality: the dataset of the corresponding date for the supplied AOI will be provided.
The many data products and imagery layers derived from MODIS observations describe features of the land, oceans and the atmosphere that can be used for studies of processes and trends on local to global scales. Examples of other MODIS derived data are NDVI (rolling 8-day average), MODIS Aqua Corrected Reflectance, and MODIS Terra Corrected Reflectance. For more information about this data and use cases, please see the provider website.
The full list of GIBS available imagery layers can be found here. With this block, UP42 supports around 80 imagery layers that have the same extent and resolution as the MODIS RGB layer (‘MODIS_Terra_CorrectedReflectance_TrueColor’).
The source code is published as Free Software and Open Source and is intended to help you build your own custom data block from scratch. The source code can be found in this repository.
Note that the output layers need to be specified in the array ‘imagery layers’ in the Job Configuration step.
