30 meters
Landsat 7 ETM+ images consist of eight spectral bands with a spatial resolution of 30 meters for bands 1 to 7.

What is the spectral resolution of Landsat?

Landsat 8 Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) images consist of nine spectral bands with a spatial resolution of 30 meters for Bands 1 to 7 and 9.

What is the temporal resolution of Landsat?

Landsat 7 data has eight spectral bands with spatial resolutions ranging from 15 to 60 m (49 to 197 ft); the temporal resolution is 16 days. Landsat images are usually divided into scenes for easy downloading.

Which bands are better for soils?

Band 4 is useful for crop identification and emphasizes soil-crop and land-water contrast. Band 5 (1.55 – 1.75u m): is sensitive to the turgidity or amount of water in plants. Band 5 has separated forest lands, croplands, water body distinctly.

What is the sensor of Landsat 7?

Enhanced Thematic Mapper Plus
Landsat 7 Instrument Landsat 7 carries the Enhanced Thematic Mapper Plus (ETM+) sensor, an improved version of the Thematic Mapper instruments that were onboard Landsat 4 and Landsat 5. Landsat 7 products are delivered as 8-bit images with 256 grey levels.

Is Landsat 7 active or passive?

Landsat satellites are another example of passive remote sensing systems. The satellites have a combination of spectral sensors aboard that are specific for Earth observation. Landsat 7 and Landsat 8 satellites are the only that remain active today.

What is meant by temporal resolution?

Temporal resolution is defined as the amount of time needed to revisit and acquire data for the exact same location. Temporal resolution is usually expressed in days.

Which band is important for land water demarcation?

Band combination: NIR (4), SWIR1 (5), Red (3) This band combination is very helpful when you intend to pick out land from water.

What is the purpose of Landsat 7?

Launched on 15 April 1999, Landsat 7’s primary goal is to refresh the global archive of satellite photos, providing up-to-date and cloud-free images. The Landsat program is managed and operated by the United States Geological Survey, and data from Landsat 7 is collected and distributed by the USGS.

What is the resolution of the new bands of Landsat 8?

Landsat 8 Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) images consist of nine spectral bands with a spatial resolution of 30 meters for Bands 1 to 7 and 9. New band 1 (ultra-blue) is useful for coastal and aerosol studies. New band 9 is useful for cirrus cloud detection. The resolution for Band 8 (panchromatic) is 15 meters.

What are the band 6H and band 6L gain settings for Landsat 7?

Landsat 7 acquires thermal data in two bands from one detector in both high (Band 6H) and low (Band 6L) gain. The difference in gain settings is important to different types of studies (i.e., clouds vs. deserts).

What is the resolution of Landsat 1-5 Multispectral Scanner?

Landsat 1-5 Multispectral Scanner (MSS) Landsat 1-3 Landsat 4-5 Wavelength (micrometers) Resolution (meters) Band 4 Band 1 0.5-0.6 60 Band 5 Band 2 0.6-0.7 60 Band 6 Band 3 0.7-0.8 60 Band 7 Band 4 0.8-1.1 60
