How to Plot Spectral Response Curve in Google Earth Engine
In This Video, i will present how to plot spectral Response Curve in Google Earth Engine
The Earth's land surface reflects about three percent of all incoming solar radiation back to space. The rest is either reflected by the atmosphere, or absorbed and re-radiated as infrared energy. The various objects that make up the surface absorb and reflect different amounts of energy at different wavelengths. The magnitude of energy that an object reflects or emits across a range of wavelengths is called its spectral response pattern.
Spectral response patterns are sometimes called spectral signatures. This term is misleading, however, because the reflectance of an entity varies with its condition, ...

How to Calculate LST and Time Series Analysis in Google Earth Engine|| GEE
Просмотров 11814 дней назад
In this Tutorial I will present how to calculate LST and Time Series Analysis Land surface temperature (LST) is the radiative skin temperature of the land derived from solar radiation. LST measures the emission of thermal radiance from the land surface where the incoming solar energy interacts with and heats the ground, or the surface of the canopy in vegetated areas. LST is a mixture of vegeta...

How to Calculate NDSI Using Google Earth Engine || GEE
Просмотров 4643 месяца назад
In this Video i will present how to calculate Normalized Difference Snow Index by using Google Earth Engine. The Normalized Difference Snow Index (NDSI) was designed to estimate the amount of a pixel covered in snow (Riggs et al. 1994): NDSI = (green - SWIR) / (green SWIR) Snow is one of the common global climatological phenomenon well-known to be a serious constituent of the hydrological serie...
How to Import Shapefile in RStudio
Просмотров 1,1 тыс.3 месяца назад
In this video, i will present how to upload shapefile in RStudio. We will use the sf package to work with vector data in R. Notice that the rgdal package automatically loads when sf is loaded. We will also use the raster package, which we will work with in more detail in later episodes, so we can explore raster and vector spatial metadata using similar commands. Make sure you have the sf librar...

what if rgdal won't download?
thank you for the tutorial I'm curious about whether multiplication of scale and offset is needed to determine the band? for example when using Landsat (developers.google.com/earth-engine/datasets/catalog/LANDSAT_LC09_C02_T1_L2) Do I need to multiply the data first by 2.75e-05 and add (-0.2) and then do the NDVI calculation? Thank you for the help
please do this again without the music, I can't hear you at all.
WOW!!!!!!! Thank you very much
Muchas gracias exelente explicación
I don`t know why, but image is grey, the program ignore the pallete
