Blog

We've been faithfully providing daily global imagery from MODIS, VIIRS, and other instruments for the last 7+ years and we're now entering new territory - we're going to provide a rolling month of geostationary imagery from GOES-East, GOES-West and Himawari-8. 

That's imagery available at 10 MINUTE increments for the last month!

Our current offerings will be Red Visible, Clean Infrared and Air Mass. We may add more in the future, or provide higher resolution versions of this imagery - keep an eye on the blog for any updates!  In particular, the Red Visible layer is currently being displayed at 1km spatial resolution but may be available at its native 500m in the future.

Step 1: Load Geostationary Imagery


Step 2: Set Up Timeline

  • Note the change in the timeline! You can now see the Year, Month, Day AND the time in Hours and Minutes Z (Zulu Time which is equivalent to UTC - Coordinated Universal Time) on the left side of the timeline.
  • To the right of the "Z" are the < > increment arrows. Click on "1 Day" above these to change the increment. There are several options - Year, Month, Day, Hour, Minute and Custom. Click on Custom and in the Custom Interval Selector box, change the increment to "10" and "Minute". (This imagery is available in 10 minute increments starting at 00:00)
  • Click on "Day" on the right side of the timeline to change the timescale to "Minute" or "Hour".

TIP: The geostationary imagery from GOES-East, GOES-West and Himawari-8 is available in 10 minute increments starting at 00:00. 

Step 3: View Geostationary Imagery and Step Through Time!

  • Enter 2019 SEP 02 17:00 Z in the timeline.
  • The GOES-East disk will update to the new date and time and show a greyscale image. 
  • Zoom into the Bahamas/Florida. Here you can see Hurricane Dorian the day after it made landfall on the Bahamas.
  • Add another layer such as "Clean Infrared (10.3 um, Band 13, 10 minute)"
  • Click on the forward increment arrow to see the image change at 10 minute increments. The change will be almost imperceptible as the imagery is loading. Click on the back arrow several times to cache the imagery and click on the forward arrow again, you will be able to see the storm's rotation.

TIP: The Red Visible layer is only available during the daytime; the Clean Infrared and Air Mass layers are available all day!

Step 4: Set Up Animation

  • To make it even easier to watch the storm's progression, set up an animation! 
  • Click on the Video Camera icon in the timeline.
  • Set the second date and time fields to 2019 SEP 02 21:00 Z; set the first date and time fields to 2019 SEP 02 17:00 Z.
  • Click on the "Play" button and watch the storm move!
  • Click on the "Create Animated GIF" icon on the right to download an animated GIF of the animation, like below:

Worldview's camera tool (upper right) in action

The resulting image after clicking "Download" in the camera tool


Summary: we've swapped out the backend service to Worldview's camera tool; you shouldn't notice a thing unless you're scraping directly from the (undocumented / deprecated) backend service.


If you've used Worldview's camera tool in the upper right corner of the app, you may have noticed that it can open a new window with a URL like this:

https://gibs.earthdata.nasa.gov/image-download?TIME=2018229&extent=-127.6736,50.0986,-119.3484,56.6041&epsg=4326&layers=MODIS_Terra_CorrectedReflectance_TrueColor,Coastlines,MODIS_Fires_Terra&opacities=1,1,1&worldfile=false&format=image/jpeg&width=947&height=740

That URL requested a custom image with your specified bounding box, layers, file format, output resolution, etc... using the legacy "Image Download" service.  With the advent of the new Worldview Snapshots tool and backend, we've consolidated how those custom images are generated.  In fact, we've already transitioned the Worldview camera tool to use the Worldview Snapshots backend.  So the same request above now looks like this:

https://wvs.earthdata.nasa.gov/api/v1/snapshot?REQUEST=GetSnapshot&TIME=2018-08-17&BBOX=50.0986,-127.6736,56.6041,-119.3484&CRS=EPSG:4326&LAYERS=MODIS_Terra_CorrectedReflectance_TrueColor,Coastlines,MODIS_Terra_Thermal_Anomalies_All&FORMAT=image/jpeg&WIDTH=947&HEIGHT=740

As mentioned in the Summary, this shouldn't have an impact on regular Worldview usage.  This post is geared toward those who are still directly using the undocumented, and now deprecated, "Image Download" service - we know you're out there!  You'll need to transition your current requests by either

We plan to decommission the "Image Download" service in April Summer 2019 which will then return a static image with an error message and pointer to this page.

Please contact us at support@earthdata.nasa.gov if you have any questions or concerns.



First released in 1999, the Open Geospatial Consortium (OGC) Web Map Service (WMS) has been a stalwart of standards used to flexibly serve map-based imagery through an HTTP interface for two decades.  While GIBS has long used the newer OGC Web Map Tile Service (WMTS) to rapidly distribute its earth science data visualizations, we've found that there are still a number of use cases which are better served by the WMS interface.  These include:

  • Geographic Information System (GIS) Client Support - users can configure their GIS client to interact with the WMS interface to facilitate an interactive experience with the GIBS visualizations.
  • Custom Image Request - users can interact directly with the WMS interface to request custom images defined by their own bounding box and output dimensions, layer list and order, and output format.

Our new service is available in the "Geographic" (EPSG:4326), Web Mercator (EPSG:3857), Arctic polar stereographic (EPSG:3413), and Antarctic polar stereographic (EPSG:3031) projections.  And, of course, it supports time-based access to GIBS' historical archive of visualizations.  

Check out our updated API documentation for WMS and GIS documentation to see how you might use the new GIBS WMS!

The Global Imagery Browse Services (GIBS) and Worldview Teams have developed a new tool called Worldview SnapshotsWorldview Snapshots is a lightweight tool for creating image snapshots from a selection of popular NASA satellite imagery layers provided through GIBS.


You can preview and download imagery in different band combinations and add overlays on the imagery of active fire/thermal anomalies detections, coastlines, borders and roads. Once you've selected your desired area of interest and parameters - map projection, date, layers, bounding box, and image file options - click on the "Preview" button. Saving the URL in the "Share Image" box in the Preview pane and clicking the checkbox next to either "Always show today" or "Always show yesterday" will ensure that every time you visit that URL you will always get today's image or yesterday's image depending on which option you picked. Click on "Download Image" to get your desired image.


If you're familiar with Rapid Response, you may know that it is being decommissioned and Worldview Snapshots is its replacement. If you like to maintain your Rapid Response Subset bounding boxes, the links on this page will direct you to the same Rapid Response bounding box area in Worldview Snapshots.


Learn more about Worldview Snapshots in this article: Introducing Worldview Snapshots and start using Worldview Snapshots - https://wvs.earthdata.nasa.gov

We’ve been working so hard this past year that we forgot to keep our blog up to date! Never fear, we are here now to bring you up to speed on all of the new and shiny features and layers we provide in Worldview.

The most recent and most exciting update: We’ve added a comparison feature! Compare the same imagery from two different dates, compare different imagery for the same date or whatever combination of the above that you like! The comparison feature provides 3 different tools to investigate the imagery – swipe, opacity, and spy. The comparison feature aids in investigating changes between two time periods or quickly comparing different types of imagery on the same date.

Getting Started with the Comparison Tool

  • Go to https://worldview.earthdata.nasa.gov

  • Click on “Start Comparison”

  • The layer list on the left will now show two tabbed layer lists labeled “A” and “B”. Tab A shows the current day, and tab B shows the previous day. The timeline also has “A” and “B” selectors to show which date you are on.

  • The map now shows the Swipe mode: A vertical line has appeared on the map with the left side labeled “A” and the right side labeled “B”. Click and hold your mouse on the line and move the line left and right to see the changes from one date to another.

  • You can also change the Compare Mode to Opacity and Spy. Opacity fades from one day’s image to another; spy positions a circular looking glass on the map showing the B state within the circle.

  • Click on “Exit Comparison” to get out of Comparison mode. You’ll be left on the last tab you had active - maintaining the layers and the date you were last on.

Some interesting comparisons to start you off:


This animated GIF demonstrates Worldview's Comparison feature, using the Opacity mode. It demonstrates changes in the Aral Sea in Kazakhstan and Uzbekistan, between 31 July 2000 (A) and 24 August 2017 (B). 

This screenshot demonstrates Worldview's Comparison feature, using the Swipe mode. Snowfall (shown in red using the Corrected Reflectance, Bands 3-6-7 combination) in Lesotho in southern Africa is shown on the left hand side (A) on 11 August 2018, and no snow a few days before on the right hand side (B) on 8 August 2018. 


-- Stay tuned for an update on our other new features and abundant new imagery layers!

Worldview and the Global Imagery Browse Services (GIBS) are now offering near real-time true/natural color (RGB) and infrared color (NGB) imagery from the Multi-angle Imaging Spectro-Radiometer (MISR) instrument on the Terra satellite. The imagery are available for the nadir, four fore and four aft views provided by MISR's nine cameras.

That's looking at the earth from 9 different angles in two different band combinations - a total of 18 imagery products!

The true/natural color imagery use the Red-Green-Blue (RGB) band wavelength combination to produce images that is similar to what the human eye would see, providing natural-looking images of land surface, oceanic and atmospheric features. The infrared color imagery uses the Near Infrared-Green-Blue (NGB) band wavelength combination to produce images that make it easier to differentiate between types of vegetation and shows vegetation in red, it's also good for identifying surface water.

The spatial resolution of the natural color imagery is 250m. Imagery for the infrared color radiance is at 1 km for the eight off-nadir views and 250m for the nadir view.

The imagery is produced from the MISR Level 1 ellipsoid-projected radiance data products by NASA’s Land, Atmosphere Near real-time Capability for EOS (LANCE) MISR Element at NASA’s Atmospheric Science Data Center (ASDC). These products are generally accessible within two to three hours of a satellite overpass, and are available for viewing through NASA’s Worldview or similar GIBS client systems. Imagery for these products is available from 1 September 2017 to present.

While LANCE near real-time products are not intended to take the place of data products generated by the detailed processing necessary for scientific research, they are an invaluable resource for users needing rapid, continually updated views of ongoing Earth processes.

Learn more about the imagery

We've made some improvements and now you can find the layer descriptions anytime you bring up a layer. In the past, the descriptions were fairly difficult to find.

Whether you're scrolling through the categories, doing a search in the Layer Picker or even once you've loaded the layer into the Layer List, the descriptions are there!

Share with your friends

When you've found an awesome image in Worldview, you can now share the URL with your friends in Facebook, Twitter (#NASAWorldview), Reddit and via email. Just click on the share icon in the top right corner of Worldview.

Find out when something's gone awry (or when something awesome has been added to Worldview!)

Worldview's incorporated a notification system so that you will be notified within Worldview if imagery delivery has been delayed or system maintenance is in progress. You might even find out if a new and exciting feature has been added to Worldview!

 

Coming soon...

We're always working on improving Worldview and cooking up the next new feature(s)! Currently, were working on improving our search function and improving the browse and interaction with the Events feed. Check out our new Roadmap to see what our near-, mid- and long-term goals are and what we're prioritizing to work on next!

Worldview 1.4.0 release - New features galore!

Worldview has incorporated some exciting new features to help you explore the planet! In addition to the features mentioned below, we have also included an auto-disable function which prevents a layer from being turned on if there is no imagery available for that date.

Continuous view of the Pacific Ocean

Imagery layers like the MODIS or VIIRS Corrected Reflectance and some other daytime layers can now be viewed over the dateline/antimeridian for the day prior to and after the current date displayed. This allows for an unbroken view of the Pacific Ocean as observed by the satellites. 

It is now possible to view the Pacific Ocean in a continuous, unbroken view in Worldview. Imagery to the left of the dateline/antimeridian displays April 14 while the imagery to the right of the dateline/antimeridian is April 13.

Fiji is an archipelagic country comprised of 300+ islands. Worldview’s new feature allows you to view the entire country since imagery is now displayed across the dateline/antimeridian. Imagery on the left is for April 9 and imagery on the right is for April 8.

Find the information that you’re interested in

Users can now view the data value under the cursor in the respective layer's legend/color bar for relevant discrete/continuous data visualization layers.

Hover over any location on a layer with a legend/color bar. You will be able to see the corresponding value to that color in the legend. Hovering over the location off the coast of West Africa, where a dust storm is occurring shows an Aerosol Optical Depth of 0.695 – 0.7.

Close up of the legend showing the corresponding image data value.

Updates to the Natural Events Feed – Easier to find events and distinguish between events

A marker or bounding box has been added to illustrate an event’s location shown in the Events feed.

Marker showing the location of Tropical Storm Maarutha on April 15, 2017

Bounding box showing the location of the Parliament Fire in Florida on March 21, 2017

Icons have been added to differentiate between natural event categories in the Events feed.

Natural events icons – Many thanks to our newest contributor, CodeMacabre, for developing these beautiful icons!

 

VIIRS Outage - RESOLVED

Update 2017/03/23 20:10 UTC: this issue has been resolved between GIBS and the data provider, VIIRS imagery should now be up to date and being processed.  Please report any problems to support@earthdata.nasa.gov and thanks for your patience!


VIIRS near real-time products and some MODIS near real-time atmosphere products have been unavailable in GIBS since March 20, 2017 due to operating system upgrades on the imagery provider's web site.

We are working with the provider to resolve the issues. Sorry for the inconvenience.

Based on directives from the US Department of Homeland Security, we are required to transition our public-facing web services to use the HTTPS protocol and deprecate support for HTTP.  

All of our production web services currently support both HTTP and HTTPS, though beginning on March 13, 2017, any HTTP requests will return a “301 Moved Permanently” response code which most browsers will automatically redirect to use HTTPS.  Hopefully this transition will be seamless to most of you - please see here if any action is needed on your part:


Tool / LibraryImpact
Worldview usersUnaffected as it already uses HTTPS to retrieve GIBS imagery
OpenLayers / Leaflet / Cesium mapping librariesWill automatically redirect GIBS requests to HTTPS although this may incur extra network traffic during initial HTTP exchanges
Script-based access using GDALWill automatically redirect GIBS requests to HTTPS although this may incur extra network traffic during initial HTTP exchanges
Your custom mapping appUnknown!  Please see below for ways to test and upgrade

 

For most developers, this update should involve simply changing the GIBS service endpoint from http to https.  Here is a sample of previous endpoints for HTTP-based “geographic” tile requests:

http://map1.vis.earthdata.nasa.gov/wmts-geo/  (circa 2011-2016)

http://gibs.earthdata.nasa.gov/wmts/epsg4326/best/  (2016+)

 

These URLs should now be replaced by their HTTPS equivalent, e.g:

https://gibs.earthdata.nasa.gov/wmts/epsg4326/best/  (2016+)

 

See here for our full API documentation:

https://wiki.earthdata.nasa.gov/display/GIBS/GIBS+API+for+Developers

 

If you would like to test how your HTTP-based application will respond to the HTTP 301 redirect before the transition on March 13, 2017, you can use our User Acceptance Testing (UAT) environment which already has the redirect in place:

http://uat.gibs.earthdata.nasa.gov/wmts/epsg4326/best/

 

Please contact us at support@earthdata.nasa.gov if you have any questions or concerns.

We are excited to announce the VIIRS Nighttime Imagery (Day/Night Band, Enhanced Near Constant Contrast) layer has been added to GIBS and Worldview!

This imagery shows the earth’s surface and atmosphere using a sensor designed to capture low-light emission sources, under varying illumination conditions. It is displayed as a grey-scale image. Sources of illumination include both natural and anthropogenic sources of light emissions. Lunar reflection can be used to highlight the location and features of clouds and other terrestrial features such as sea ice and snow cover when there is partial to full moon conditions. When there is no moonlight, natural and anthropogenic night time light emissions are highlighted such as city lights, lightning, auroras, fires, gas flares, and fishing fleets.

This layer is useful for showing patterns of human activity and energy behaviors such as cities and highways, the holiday periods, the tracking of shipping and fishing fleets at night and, the burning of waste natural gas (gas flares) from on and off shore oil/gas production sites.

 

Examples of the VIIRS Nighttime Imagery (Day/Night Band, Enhanced Near Constant Contrast)

 

This layer is updated daily, unlike the VIIRS Earth at Night 2012 image. The 2012 Earth at Night image was an image composite assembled from clear, cloud free images from 9 days in April 2012 and 13 days in October 2012.

The VIIRS Nighttime Imagery (Day/Night Band, Enhanced Near Constant Contrast) layer is available from the Visible Infrared Imaging Radiometer Suite (VIIRS) on the joint NASA/NOAA Suomi National Polar orbiting Partnership (Suomi-NPP) satellite. The sensor resolution is 750 m at nadir, imagery resolution is scaled to 500 m, temporal resolution is daily and temporal range for viewing in Worldview/Global Imagery Browse Services (GIBS) is 30 November 2016 - present.

New and improved GIBS

In the Spring of 2016, the GIBS team deployed a new operational system (GIBS 1.0) with superior data storage, performance, and capabilities to the beta system it replaced. The release of GIBS 1.0 allowed for a doubling of its imagery products in 2016, both in number and storage. This has been accomplished along with a reduction in latency for NRT imagery and with a continuation of GIBS’ responsive request performance.  The GIBS team continues to work closely with its user community to define and add new imagery products and features such as sub-daily (e.g., granules), vector-based, and vertical profile data visualizations.

 

The beta version of GIBS was initially released in 2011 enabling visual discovery and comparison of interdisciplinary science parameters by providing full resolution visual representations of NASA Earth science data in a free, open, and interoperable manner. Through responsive and highly available web services, GIBS now provides quick access to over 400 satellite imagery products, covering every part of the world. Many imagery products represent near real-time (NRT) data and are available within three hours after satellite overpass. Other imagery products span the entire science mission, up to 30 years of observation.

New Features in Worldview

Natural Events Tab

This feature was added in collaboration with NASA Earth Observatory’s Natural Event Tracker (EONET). EONET provides a curated list of current natural events and hazards such as wildfires, severe storms and volcanic eruptions. Worldview uses this event list to provide users the ability to easily view pertinent GIBS imagery layers for the date(s) and geographical area of a selected event.

 

Animation

The new animation feature allows users to create, download, and share animations that more easily demonstrate the dynamic processes shown in the imagery.

Push the play button at the bottom/center of the screen here to watch the Yosemite Rim Fire grow in size and change the underlying landscape:

Here’s an example showing the calving of iceberg B-31 from Antarctica’s Pine Island Glacier:

Polar Rotation

Users are now able to rotate the imagery in the Arctic and Antarctic views. The user now has the power to decide what direction is "up".

Coming soon...

Keep your eyes peeled for new features and improvements in Worldview!

Update on 2016 April 13: generation of Terra / MODIS atmospheric products has now restarted as of 2016 April 8.  Likewise, atmospheric imagery from that date forward is now available in GIBS. See here for full details:

Original post from 2016 March 3:

The Terra spacecraft along with its MODIS instrument entered safe mode on 2016 February 18 during an inclination adjustment maneuver (IAM).  It recovered from safe mode into normal mode on February 22 and reentered into science operations on February 24.  Data will therefore be missing between February 18-24.  

Though the data is currently being acquired and processed, the resulting data products are degraded and are not expected to meet science quality due to instrument temperatures not yet reaching their normal operating value.  Most atmosphere products and some land products are disabled.  As of 2016 February 4 000z, land products will resume processing and atmosphere products will resume at a future date.

GIBS imagery products are dependent on these data products and will be produced accordingly.
