# What does the path row mean with the Landsat 5 data?

## What does the path row mean with the Landsat 5 data?

Row refers to the latitudinal center line of a frame of imagery. As the satellite moves along its path, the observatory instruments are continuously scanning the terrain below.

### What is path and row in Landsat?

The Worldwide Reference System (WRS) is used to identify the path and row of each Landsat image. The path is the descending orbit of the satellite. Each path is segmented into 119 rows, from north to south. The Landsat MSS sensor had a swath width of 180 km and global coverage required 251 paths.

What is Path in remote sensing?

The transmission path is the space between the electromagnetic energy source and the target, and back to the sensor. In the case of Earth observation, the transmission path is usually the atmosphere of Earth.

Is Landsat 5 still operating?

After 29 years in space, Landsat 5 was officially decommissioned on June 5, 2013. Near the end of its mission, Landsat 5’s use was hampered by equipment failures, and it was largely superseded by Landsat 7 and Landsat 8.

## What are the Landsat 5 bands?

Seven spectral bands, including a thermal band:

• Band 1 Visible (0.45 – 0.52 µm) 30 m.
• Band 2 Visible (0.52 – 0.60 µm) 30 m.
• Band 3 Visible (0.63 – 0.69 µm) 30 m.
• Band 4 Near-Infrared (0.76 – 0.90 µm) 30 m.
• Band 5 Near-Infrared (1.55 – 1.75 µm) 30 m.
• Band 6 Thermal (10.40 – 12.50 µm) 120 m.

### How is Landsat 5 NDWI calculated?

NDWI = (G-NIR)/(G+NIR) The Normalized Difference Water Index (NDWI) is derived from the Near-Infrared (NIR) and Green (G) channels. This formula highlights the amount of water in water bodies.

What is path and row?

Row refers to the latitudinal center line of a frame of imagery. As the satellite moves along its path, the observatory instruments are continuously scanning the terrain below. A total of 119 Landsats 1-3 daylight scenes are possible along one descending satellite path.

What is a Landsat scene?

The Landsat program is the longest-running enterprise for acquisition of satellite imagery of Earth. It is a joint NASA / USGS program. Each Landsat scene is about 115 miles long and 115 miles wide (or 100 nautical miles long and 100 nautical miles wide, or 185 kilometers long and 185 kilometers wide).

## When did Landsat 5 end?

June 5, 2013
On June 5, 2013, the U.S. Geological Survey Flight Operations Team transmitted the last command to the Landsat 5 satellite, effectively terminating the mission 29 years, 3 months and 4 days after its launch by NASA from Vandenberg Air Force Base on March 1, 1984.

### How long was Landsat 5 Operational?

28 years and 10 months
Outliving its three-year design life, Landsat 5 delivered high-quality, global data of Earth’s land surface for 28 years and 10 months. NASA launched Landsat 5 from Vandenberg Air Force base in Lompoc, Calif. on March 1, 1984.

Which band is Nir in Landsat 5?

Landsat 8 Operational Land Image (OLI) and Thermal Infrared Sensor (TIRS)

Band Wavelength
Band 5 – Near Infrared (NIR) 0.85-0.88
Band 6 – Short-wave Infrared (SWIR) 1 1.57-1.65
Band 7 – Short-wave Infrared (SWIR) 2 2.11-2.29
Band 8 – Panchromatic 0.50-0.68

What does row Mean on a Landsat satellite?

Row refers to the latitudinal center line of a frame of imagery. As the satellite moves along its path, the observatory instruments are continuously scanning the terrain below. These will be squares centered on the orbital path, but tilted clockwise when viewed on the UTM projection used for the distributed data.

## What was the life span of the Landsat 5?

Landsat 5 data were acquired on the Worldwide Reference System-2 (WRS-2) path/row system, with swath overlap (or sidelap) varying from 7 percent at the Equator to a maximum of approximately 85 percent at extreme latitudes. Landsat 5 long outlived its original three-year design life.

### Which is the descending node in Landsat 7?

Landsat 7 acquires data in descending (daytime) node, while Landsat 8 acquires data in both descending and occasional ascending (nighttime) node. Row refers to the latitudinal center line of a frame of imagery.

How to convert Lat to path in Landsat?

Go to https://landsat.usgs.gov/wrs-2-pathrow-latitudelongitude-converter and enter the lat/long. Then note the path row, and when you get the Landsat data, insure you have the correct path and row, which are listed in the download table.
