Geographic Base Map: ArcGIS Online World Imagery
World Imagery, last updated August 2017, provides one meter or better
satellite and aerial imagery in many parts of the world and lower
resolution satellite imagery worldwide. The map includes 15m TerraColor
imagery at small and mid-scales (~1:591M down to ~1:72k) and 2.5m SPOT
Imagery (~1:288k to ~1:72k) for the world. The map features 0.3m
resolution imagery in the continental United States and parts of
Western Europe from DigitalGlobe. Additional DigitalGlobe sub-meter
imagery is featured in many parts of the world. In the United States,
1 meter or better resolution NAIP imagery is available.
In other parts of the world, imagery at different resolutions
has been contributed by the GIS User Community. In select communities,
very high resolution imagery (to 0.03m) is available down to ~1:280
scale.

This layer provides access to NASA Global Imagery Browse Services,
which delivers global, full-resolution satellite imagery.
This band composition (Bands 1 4 3) most accurately represents how we see the earth's
surface with our own eyes.
Data Products
GEDI L1B: Geolocated Waveform Data Global Footprint Level
The GEDI Level 1B Geolocated Waveforms product (GEDI01_B) provides geolocated corrected and smoothed waveforms, geolocation parameters, and geophysical corrections for each laser shot for all eight GEDI beams. GEDI01_B data are created by geolocating the GEDI01_A raw waveform data. The GEDI01_B product is provided in HDF5 format and has a spatial resolution (average footprint) of 25 meters.
Additional information can be found in the GEDI L1B Product Data Dictionary.
GEDI L2A: Elevation and Height Metrics Data Global Footprint Level
The purpose of the GEDI Level 2A Geolocated Elevation and Height Metrics product (GEDI02_A) is to provide waveform interpretation and extracted products from each GEDI01_B received waveform, including ground elevation, canopy top height, and relative height (RH) metrics. The methodology for generating the GEDI02_A product datasets is adapted from the Land, Vegetation, and Ice Sensor (LVIS) algorithm. The GEDI01_B product is provided in HDF5 format and has a spatial resolution (average footprint) of 25 meters.
Additional information can be found in the GEDI L2A Product Data Dictionary.
GEDI L2B: Canopy Cover and Vertical Profile Metrics Data Global Footprint Level
The purpose of the GEDI Level 2B Canopy Cover and Vertical Profile Metrics product (GEDI02_B) is to extract biophysical metrics from each GEDI waveform. These metrics are based on the directional gap probability profile derived from the L1B waveform. Metrics provided include canopy cover, Plant Area Index (PAI), Plant Area Volume Density (PAVD), and Foliage Height Diversity (FHD). The GEDI02_B product is provided in HDF-5 format and has a spatial resolution (average footprint) of 25 meters.
Additional information can be found in the GEDI L2B Product Data Dictionary.
