You will see the default image properties for this drawing.Import the file as a background using View > Background > New > New File.Open WaterGEMS and create a new hydraulic model.Save the image using File > Save > Save Image and assign the image a file name.Usually a 1000 ft is a good length as shown below: Using Tools > Ruler, draw a straight line with a known length (in an inconspicuous part of the image). Make certain that the view is vertical straight down (not tilted). Open the Google Earth image and zoom to the extents that will be used for the model.To receive notifications from GIBS and Worldview about updates, announcements, data issues and scheduled maintenance, follow our blog or subscribe to the GIBS mailing list, by sending an email to join (no subject or text in the body is needed). View frequently asked questions (FAQ) about Worldview. We encourage interested developers to build their own clients or integrate NASA imagery into their existing ones using these services.Ĭomments/suggestions/problem reports are welcome via Earthdata Support. While Worldview uses OpenLayers as its mapping library, GIBS imagery can also be accessed from Cesium, ArcGIS, GDAL, several other clients. Worldview uses NASA's Global Imagery Browse Services ( GIBS) to rapidly retrieve its imagery for an interactive browsing experience.

Users can preview and download imagery in different band combinations and add overlays on the imagery of active fire detections, coastlines, borders, and roads. Browsing on tablet and smartphone devices is generally supported for mobile access to the imagery.Īlso available is Worldview Snapshots, a lightweight tool for creating image snapshots from a selection of popular NASA satellite imagery layers. Arctic and Antarctic views of many products are also available for a "full globe" perspective. These full disk hemispheric views allow for almost real-time viewing of changes occurring around most of the world. These are provided in ten minute increments for the last 90 days. Geostationary imagery layers are also now available. View current natural hazards and events using the Events tab which reveals a list of natural events, including wildfires, tropical storms, and volcanic eruptions. This supports time-critical application areas such as wildfire management, air quality measurements, and flood monitoring. Many of the imagery layers are updated daily and are available within three hours of observation - essentially showing the entire Earth as it looks "right now". The Worldview tool from NASA's Earth Observing System Data and Information System ( EOSDIS) provides the capability to interactively browse over 1000 global, full-resolution satellite imagery layers and then download the underlying data.
