Resampling hyperspectral data to Landsat 5 TM bands
Hiking & ActivitiesWhat is spectral resampling? SpectRes: Simple Spectral Resampling¶ SpectRes is a Python function which efficiently resamples spectra and their associated uncertainties onto an arbitrary wavelength grid. The function works with any grid of wavelength values, including non-uniform sampling, and preserves the integrated flux.
Function access to surrounding object’s variable
Hiking & ActivitiesHow to access local variable outside function in JavaScript? Local variables cannot be accessed outside the function declaration. Global variable and local variable can have same name without affecting each other. JavaScript does not allow block level scope inside { } brackets. Can we use a function as a variable value?
