[58], the bands helped to emphasize regional lineaments, structures, and significant bedrock fracture zones. These cracks would be fault zones or shear zones, in accordance with [59]. To decrease highly linked multidimensional data for accurate geological interpretations, PCA is a method of linear...
In our application of METRIC, we calculated SAVI and NDVI from the Level-2 atmospherically corrected surface reflectance of these bands using the equations proposed by the LDAPS (Masek et al., 2006; Vermote et al., 2016). For SAVI, the canopy background adjustment factor (L) was taken ...
It is a combination of all Landsat TM or Enhanced Thematic Mapper Plus (ETM+) spectral bands except the thermal band, with the greatest weight given to the SWIR channel (e.g., [14]). While the use of remote sensing for detection of bark beetle infestation is well established, its ...
The current work evaluates the early on-orbit absolute radiometric calibration of the Landsat 9 OLI visible and near infrared bands using in situ-based approaches based on RadCalNet data sets. A background on the RadCalNet system, its sites, and uncertainties are provided in Section 2 followed by...

I am doing research on urban heat islands. How do I get thermal images of the area I am doing the study on? Reply GISGeographysays: May 15, 2019 at 4:16 am After you download your Landsat-8 area of interest, it will come as a zip file. Extract it. Next, you will use bands 10...
Therefore, to help speed up the interpretation, the second image acquisition was segmented into burned and unburned classes using the Mean-Shift segmentation algorithm (Comaniciu and Meer, 2002) applied to the green, red, and NIR bands. The image was over-segmented to provide many segments per...
The current state of the practice for large area multi-temporal land cover classification is to derive metrics from the time series and then classify the metrics bands with a supervised (i.e., training data dependent) non-parametric classification approach (Yan and Roy, 2015, Gómez et al., ...
