Sentinel Hub Webinar: Custom Scripts

The first live Sentinel Hub webinar highlighting Custom Scripts was held on September 24, 2020. In the first part (03:15) you will learn more about the JavaScript variables and arrays, custom composites, brightness and contrast. The second part (15:00) will introduce the conditional statements and functions, discrete and continuous visualisation, and transparency. In the third part of the webinar (50:00) we are introducing advanced scripts and custom script repository. Tune in!

We assumed the viewers are familiar with the following concepts: satellite, electromagnetic spectrum, wavelength, satellite band, raster computation, spectral signature and RGB color. In case you are not familiar with these, please visit our Custom Script Tutorial (https://www.sentinel-hub.com/docs/Cus..., pages 4 -10 (chapters 2.1 - 3.1), where you will find these concepts explained.
