Spatial Subsetting Applications

[Earthdata Search - kaewal01]

Dear Earthdata Support,
What are the different NASA originated applications that I can access to spatially subset my data to a defined shapefile?

Hi @Earthdata Search - kaewal01 The Application for Extracting and Exploring Analysis Ready Samples (AρρEEARS) would meet your needs! AppEEARS allows you to upload a shapefile or geojson or draw a polygon and will subset the data spatially for you and provide you with a nice mosaic in the end as either a GeoTiff or NetCDF-4. As a bonus you can also choose a specific projection as well.

[GES DISC - jimacker]

The GES DISC offers spatial subsetting for many datasets, accessible through the main data ordering interface. First search for the datasets of interest, using keywords in the search box on the home page. In the returned list, if the words "Subset/Get Data" appear under the dataset name, these data can be subset. In addition to spatial subsetting, they can also be temporally subset or by variable.

The Giovanni system (https://giovanni.gsfc.nasa.gov/) provides spatial and temporal subsetting for all of the data variables (Level 3 data) in the system.

Hi @@Earthdata Search - kaewal01, the ORNL DAAC provides several tools/services that you can use to subset data spatially.

• Terrestrial Ecology Subsetting & Visualization Services, formerly "MODIS/VIIRS Subsets Tool", allows you to subset selected land data products from MODIS, VIIRS, SMAP, ECOSTRESS, GEDI, ICESat-2, etc. for any location, area, and time period globally. Link: https://modis.ornl.gov/

• THREDD Data Server allows you to subset selected ORNL DAAC-archived data through the OPeNDAP and NetCDF Subset Service APIs. Link: https://thredds.daac.ornl.gov/thredds/

• Spatial Data Access Tool allows you to subset selected ORNL DAAC-archived data through the OGC Web Coverage Service (WCS) API in GIS-ready format. Link: https://webmap.ornl.gov/ogc
