Rapid error assessment for quantitative estimations from Landsat 7 gap-filled images

Rapid error assessment for quantitative estimations from Landsat 7 gap-filled images | Télédétection veille IST INRAE & AgroParisTech | Scoop.it

The failure of the Scan Line Corrector (SLC) of the Landsat ETM+ (Enhanced Thematic Mapper Plus) instrument in 2003 had resulted in missing values for 22% of each scene. As the remaining pixels were of high quality, several procedures had been developed to fill the gaps and increase the usability of the SLC-off images. In this letter, a methodology is presented to assess the error when estimating quantitative parameters from gap-filled Landsat 7 images. The error from the gap-filling procedure was estimated using an external reference image. The methodology was applied in a Mediterranean river basin using two types of gap-filling methods and the error was estimated for leaf area index (LAI), actual evapotranspiration (ETa) and soil moisture in the rootzone (SMrz), three remotely sensed products which are commonly used in hydrological studies. The results suggest that the interpolation method had lower errors in all examined products. The proposed methodology is an imperative step that each user of gap-filled products could use to estimate the associated error before using the maps.

Using the USGS Landsat 8 Product

Using the USGS Landsat 8 Product | Télédétection veille IST INRAE & AgroParisTech | Scoop.it

The standard Landsat 8 products provided by the USGS EROS Center consist of quantized and calibrated scaled Digital Numbers (DN) representing multispectral image data acquired by both the Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS).  

 

The products are delivered in 16-bit unsigned integer format and can be rescaled to the Top Of Atmosphere (TOA) reflectance and/or radiance using radiometric rescaling coefficients provided in the product metadata file (MTL file), as briefly described below.  The MTL file also contains the thermal constants needed to convert TIRS data to the at-satellite brightness temperature.  Further details can be found in the LDCM Cal/Val Algorithm Description Document and the Landsat 8 Science Users’ Handbook available from the Landsat website.
