*The following projections are offered:

Geographic
UTM
Polar Stereographic (except for SPL2SMAP_S & SPL1CTB)

**Reprojection services (for Level-1 and -2 data sets) specifically apply to the following data formats:

GeoTIFF
net-CDF-4
HDF-EOS5

*** Reprojection services (Level-3 and -4 data sets and SPL2SMAP_S) specifically apply to the following data formats:

HDF5 (native data format)
GeoTIFF
net-CDF-4
HDF-EOS5

Shapefile subsetting:

Includes shapefile, KML/KMZ, and GeoJSON. For best results, use a WGS84 Geographic Coordinate System (EPSG: 4326) and include both the latitude and longitude parameters in the order. This service is not available for data subscriptions.
