The GIBS imagery archive includes approximately 1= 000 imagery products representing visualized science data from the NASA Ear= th Observing System Data and Information System (EOSDIS). Each imagery prod= uct is generated at the native resolution of the source data to provide "fu= ll resolution" visualizations of a science parameter. GIBS works clos= ely with the science teams to identify the appropriate data range and color= mappings, where appropriate, to provide the best quality imagery to the Ea= rth science community. Many GIBS imagery products are generated by th= e EOSDIS LANCE near real-time processing system result= ing in imagery available in GIBS within 3.5 hours of observation. These pro= ducts and others may also extend from present to the beginning of the satel= lite mission. In addition, GIBS makes available supporting imagery layers s= uch as data/no-data, water masks, orbit tracks, and graticules to improve i= magery usage.
The GIBS team is actively engaging the NASA EOSDI= S Distributed Active Archive Centers (DAACs) to add more imagery products a= nd to extend their coverage throughout the life of the mission. The remaind= er of this page provides a structured view of the layers currently availabl= e within GIBS grouped by science discipline and science observation. = For information regarding how to access these products, see the GIBS API section of th= is wiki. For information regarding how to access these products through an = existing client, refer to the M= ap Library and GIS Client sections of this wiki. If you are= aware of a science parameter that you would like to see visualized, please= contact us at support@earthdata.nasa.gov.
As noted above, imagery products within GIBS are generated based on near= real-time and standard science products. To understand the difference betw= een these two data products, review the instrument sections on the = Near real-time versus Standard Products page.
This section contains imagery from ge= ostationary satellites - Geostationary satellites are an altitude of approx= imately 35,800km (22,300 miles) directly over the equator and revolve in th= e same direction (west to east) that the Earth rotates. This altitude ensur= es that one orbit takes 24 hours which is the same length of time as the ea= rth takes to rotate once on its axis. The GOES-East satellite is cente= red on 75.2 degrees W covering the Conterminous US, Canada, Central and Sou= th America; GOES-West is centered on 137.2 degrees W, covering = most of the Pacific Ocean, the USA, most of Canada, Central, the western ha= lf of South America, parts of Australasia; and Himawari-8 is centered = on 140.7 degrees E, covering most of the Pacific Ocean, a portion of Easter= n Asia, and parts of Australasia. Learn more about this imagery on the GIBS Blog<= /a> and the Earthdata article "Now Available in NASA = Worldview: Earth Every 10 Minutes".
Multiband imagery are visible products that have been created through a = process of mapping one or more spectral bands to RGB composite image.  = ;Based on the selection of spectral band "combinations" and how they are ma= pped to the RGB visible bands, different observations will be made more app= arent. As an example, the MODIS instrument has 7 spectral bands that = are typically used to generate a visible image. There are 210 non-rep= eating band combinations that can be generated. As such, GIBS works w= ith its imagery providers to select the "highest value" band combinations f= or visualization. The following tables identify the existing multiban= d imagery available in GIBS:
Science parameter visualizations are generated by mapping scientific mea= surements into an RGB image. Each measured value, or range of values,= is assigned a unique color to create a visual representation of the underl= ying data values. This may also apply to classification data. C= hoose one of the following science disciplines, or scroll down, to view the= imagery products available within GIBS.
While viewing the previous multi-band and science parameter visualizatio= n layers, GIBS offers the following "utility" layers to improve imagery vie= wability. These layers include data or imagery masks that highlight o= r remove specific regions of an image and also mapping aides such as gratic= ules and coastlines. The following tables identify the existing utility lay= ers within GIBS:

sup> The Imagery Resolution is the resolution of the image offered on the G=
IBS system. Generally the imagery resolution is of equal or higher resoluti=
on than the native or sensor resolution. Web Mercator imagery is generated by re-sampling the geographically projec=
ted imagery. In that process, the closest corresponding resolution i=
s used.
[2] The Sensor Resolution, also known as native resolution, is provided as = a reference not to be confused with the imagery resolution explained in&nbs= p;[1]. This is the resolution of the source product elements whi= ch went into making the imagery product served in GIBS.
