Daily Planet, a countinuously updating image of the earth, using scenes from MODIS TERRA
A dataset built for this server, available from Dec 1st 2007 as a data processing prototype. This mosaic is continuosly updated with images from MODIS TERRA, which has almost global daily coverage. This layer is the most current, near-global image of the earth available. The resolution is 250m per pixel in the middle of the swath, less on the edges. Visit the MODIS Website for more information.
New images are added on top of the old data, in the order in which they become available. In general, the latest images are between 6 and 24 hour old. The update process is automated, various errors might be visible. To produce this mosaic, 80GB per day of raw MODIS scenes are downloaded from the LAADS Web, processed using HDFLook into visual images in a global coordinate system and spliced into the current composite. Previous days are also available and can be access using the WMS time argument. Use the OnEarth_DailyPlanet.kml file to view this layer in Google Earth. A WorldKit interactive browser of this data is available here, in addition to the screen icons the arrow keys and the A and Z keys can be used to pan and zoom.
Daily Afternoon, a countinuously updating image of the earth, using scenes from MODIS AQUA
A dataset almost identical with the DailyPlanet, built from MODIS AQUA data. The AQUA satellite crosses the equatorial line on the day side of
the earth in the afternoon, around 2PM, while the TERRA satellite, the source of the DailyPlanet dataset, does so around 10AM.
For an example of the historic data available on this server, see the South California fires of October 2007 page
WMS Global Mosaic, Blue Marble background
This is also the home site of the WMS Global Mosaic, a high resolution global image mosaic of the earth, produced from more than 8200 individual Landsat7 scenes. Each scene requires more than 500MB of storage, or about one standard CD. These images have been collected during 1999-2003. The highest resolution image has a ground relative resolution of 15 meters, or 50 foot. The mosaic contains all nine spectral bands of the Landsat7 ETM+ instrument. Together with the associated Web Map Service Server, the mosaic is known as the WMS Global Mosaic.
An FGDC metadata compliant record, with more information about this dataset is available here: Metadata Link
The base dataset can be downloaded from download site
WMS The Web Map Service (WMS) server providing access to the WMS Global Mosaic and other datasets is accessed via this base URL: http://wms.jpl.nasa.gov/wms.cgi. The WMS server capabilities, an XML encapsulated document describing the datasets and the server are can be retrieved via a Capabilities Request
Clicking on an image or on a caption on this site will take you to an interactive WMS map browser. This browser has limited capabilities and is intended only to provide a funtional view of the capabilities of the map server itself. Once in the browse mode, you can click on the image to recenter the view or use the zoom bar at the top of the image to zoom. The distance left or right of the black/blue center marker controls the zoom in or out amount, up to four times the current level. The browser will let you zoom out more than a single earth width, which will generate an error, and zoom in past the level of detail of the data. Other WMS clients do exist, and they can provide more functionality than the WMS browser available on this site. worldKit can be used as a WMS client, recommended worldkit configuration entries for a number of layers from this server are provided where applicable.
Users of WorldWind or Punt should use the OnEarth.xml configuration file. Save a copy of the configuration file in the WorldWind/Config/Earth subdirectory, and use the layer manager to enable layers from this server. Four different styles of the WMS Global Mosaic are configured, together with the daily TERRA/AQUA MODIS mosaics.

30m SRTM Reflectance Image
This is the radar reflectance image produced by the SRTM mission. It is an example of the best available snapshot of the surface of the earth, being the highest resolution image collected in the shortest ammount of time, with near-global 30m coverage collected during an 11-day Endeavour mission, in February of 2000.
A radar reflectance image has little in common with a visual image, depending mostly on the material and orientation of the object. Areas with low detail such as lakes and sand tend to have no reflection, and very steep terrain can obscure certain areas from the side look ing SRTM instrument, both fenomena generating voids in the SRTM reflectance image. Urban areas tend to have stronger reflectance. The banding artifacts still visible in the images are the result of the combination of data from multiple orbits or are intrinsic to the SRTM instrument.
Five basic bands are available as WMS styles, ss1, ss2, ss3 and ss4 being SRTM image subswath averages, the all style being an average of the four subswath composites. The default style presented above is derived from the all band, using an arbitrary color map to make more detail visible. The subswath composites also available via the WMS SLD band selection mechanism, band 0 correspoinding to ss1, 1 to ss2, 2 to ss3, 3 to ss4 and 5 to all.
Starting with March 12th 2008, the MODIS Rapidfire subset composites are no longer updated. This includes the visual, pseudocolor and NDVI, for both TERRA and AQUA MODIS. The archive is still available.

The two MODIS visual color composites built on this site daily from high level Near-real-time Subsets
produced by the MODIS Rapid Response System.
The available subsets are being downloaded and combined in a single composite, at a uniform resolution of 8 arc-second per pixel or about 250m per pixel. The source images and the mosaics themselves are JPEG compressed. Some compression artifacts will be present in the composite, requesting PNG formated images will not produce better quality images
These daily composites are being archived and are available from this server using the WMS time argument. Available mosaics start on 2004-12-25. New mosaics, for the previous day becomes available around 10AM GMT, first TERRA then AQUA, the exact time of the refresh depending on the ammount of data to be processed that day. The two static jpeg images above are updated when the composites become available. A request for a non-existing day, including current and future days, will generate a black image
In addition to the visual composites above, for both TERRA MODIS and AQUA MODIS, two alternate color mappings are available, the 721 band to RGB mapping and the Normalized Difference Vegetation Index (NDVI).
Daily TERRA 721 ;
Daily AQUA 721 ; Daily TERRA NDVI ;
Daily AQUA NDVI
The 721 mapping is used to identify recently burnt areas, which appear red or brown in this mapping. Since it has increased water contrast compared with the visual images, it can be used to identify flooded areas. The NDVI is strongly correlated with the density and state of vegetation, and can be used to monitor the state of the crops. These mosaics are updated daily right after the visual composites. The image above is only updated once all four composites are complete.
More information about the various mapping is available from the Rapid Response System FAQ
There are two operational MODIS instruments, on two satellites named Aqua and Terra. More information about the MODIS instrument and data is available at the MODIS site.

There are thirtysix styles associated with the Blue Marble Next Generation layer, three styles for each month of the year. The individual links below the image are shortcuts to a browser using these styles. The styles with names ending in _ns have no shading on land or ocean, while the ones ending in _nb have no ocean bottom shading. The styles named simply after the month they represent have both land topography and ocean bathymetry shading.
A SRTM derived, 90m world elevation model
The National Elevation Dataset (NED), at 30m resolution
The NED source data is full precision floating point real numbers. It is possible to retrieve those values by requesting the real or feet_real styles and tiff or geotiff format.
In addition, the "short_int" styles described below work on this layer, when using a tiff, geotiff or PNG format.
Another continental US, 90m elevation model
The default styles for the elevation layers are a version of the elevation maps scaled to 8 bit. The full elevation values can be retrieved from this server by requesting the short_int or feet_short_int styles in combination with the image/png image/geotiff or image/tiff value for the format argument. The result of such a request will be an image where the signed short integer values contained in the image file for each pixel are the elevation of the respective point on the map, in either meters or feet. The base data is in meters. The us_ned layer base data is floating point real numbers in meters, data which can be retried in tiff or geotiff format when using the real or feet_real as styles.
All the datasets that exist on this server are documented for WMS clients in an XML formated Capabilities file.
This file contains information about the layers, which correspond to datasets, and the styles associated with them.
