Path/Row - The Landsat 7 and Landsat 8 satellites follow the World Reference System 2 (WRS-2).

Time - The time of acquisition appears in Coordinated Universal Time (UTC) using military time in hours, minutes, and seconds.

Date - The date of acquisition appears in DD MMM YYYY format.

An orange box outlines the ground track of the satellite.

Satellite Location Subset Map - This map displays the direction the satellite is taking on a larger scale.

The red stop button will close out the current feed and restart the feed to the most recent acquisitions. The yellow pause button will temporarily hold the feed at its current location.

Feed Controls - The blue circle icon toggles the names of cities and features on and off.

For EarthNow!, the band combination options include 'True Color' and 'Vegetation Analysis'. The choice of band combination will put specific sensor bands into these channels to produce an array of colors. Band Combination - Three channels can be used for visual display of Landsat's multispectral image data: red, green and blue (RGB).This sidebar also features band combination selection feed controls, the satellite location ancillary map, the date and time of acquisition, the path and row numbers, and geographical information specific to the area being displayed. The top display on the right sidebar indicates which Landsat mission is being displayed, and indicates whether it is a recorded pass or near-real time live-streaming.

They are turned on at a slightly different point in the return scan than where they were turned off, giving the imagery a jagged edge. The imaging detectors are turned off momentarily at the edge of the image.

As the satellite travels above the Earth's surface, the sensor rapidly scans the viewing area from side to side. The edges of the feed appear jagged because of the way the Landsat sensors collect image data. Each pass has a swath width between 185 and 190 kilometers (115-118.1 miles). The image feed appears on the left hand side of the screen. The screen is divided between the main display and the sidebar controls.

When no active acquisitions are being made, the most recent pass is replayed. EarthNow! allows users to see recent data acquired by the Landsat 7 and Landsat 8 satellites in near-real time.
