ENVI Band Math: How to Select Landsat Pixels with Reflectance Greater than 10%

"ENVI Band Math: How to Select Landsat Pixels with Reflectance Greater than 10%"\n\nIn ENVI software, you can use the Band Math tool to edit Landsat data pixels where the reflectance of a specific band is greater than 10%. Here are the steps to accomplish this task:\n\n1. Open ENVI software and load your Landsat data.\n2. From the ENVI menu bar, select "Raster", then "Band Math".\n3. In the Band Math dialog box, select the band you want to edit and add it to the "Input Bands" list. You can use the "Add Band" button to add bands.\n4. In the Expression area of the Band Math dialog box, enter the following expression to define the condition for pixels with reflectance greater than 10%:\n "band > 0.1"\n Where "band" is the name of the band you selected.\n5. Ensure the expression is correct and click "OK" to execute the calculation.\n6. After the calculation, a new raster layer will be generated, where only pixels with reflectance greater than 10% are retained, and other pixels are set to NoData values.\n7. You can view and analyze the generated raster layer in ENVI.\n\nNote: These steps assume you are familiar with the basic operations of ENVI software and have successfully loaded and displayed your Landsat data.
