## Why important for me?

I had previously observed remote sensing analyses but had not discovered the mathematical calculations behind how the colorization is presented to the user. Upon reading a university paper on this subject, I was delighted to find that the calculations could be done online for users through software without putting too much strain on the browser. I provided it to users for free. Hopefully, there are no errors, but if there are, I'll be ready to address and fix them. :)

### How did I decide to develop this software?

A customer of mine wanted to determine the health of plants on agricultural land using remote sensing analysis, and the vastness of the land made it feasible to conduct these analyses online. Therefore, I initially developed this software for my own use and later integrated it into my customer's system. That's the backstory of the genesis of the software.

### What Technologies Are Used?

When i started coding the web-based remote sensing analyzes software, we preferred to use current, popular, and, at the same time, future-proof technologies and elements. If we encounter a better technology in the future, i won't hesitate to adopt it.
