Here is the collections of lectures given during the Earth Educational Collective project in 2021-2022. Some videos are longer lectures on particular topics, some include brief lectures and recording of the conversation between the participants. In the latter case we linked to the beginning of the lecture.
The full recordings of all only meetings of the Earth Educational Collective could be found here: https://youtube.com/playlist?list=PL7KuBKCgcBfYHSG5L7ExIRN7htpl_-hNp

Why are satellite images so important?
|
|
 |
 |
The surface of our planet is today permanently observed from space by many various satellites. The information collected by the satellites is objective, up to the date, independent, and getting more and more publicly available.

Why the satellite images available in Google Maps are not sufficient for the detailed study of Earth
|
|
 |
|
Everyone knows Google Maps. As you know, in this portal we could see not only maps but also satellite and aerial images. There are, however, limitations for using satellite images from Google Maps.

Revealing more than we could see with our own eyes – modern multi-spectral imagery
|
|
 |
|
This lecture explains some basic principals of the optical remote sensing and of the modern multispectral satellite images. You will learn why "false colors" in satellite images could be better than "natural colors", what are spectral bands and how to combine them into multispectral images using Sentinel Hub EO Browser.

How satellite images differ from each other? (Main types of satellite imagery.)
|
|
 |
|
From this video you will learn about typical orbit parameters of a remote sensing satellites, as well as about the main characteristics of satellite imageres, including spatial, temporal, and spectral resolutions.

Drawing contours in Google My Maps and using it for locating the area in Google Earth Pro and Sentinel Hub EO Browser
|
|
 |
|
The second part of this video will guide you (again) through the process of online contours drawing and using the saved contours for locating the area in Google Earth Pro and Sentinel Hub EO Browser. Both online tools allow "timetravels" with satellite images and seing how the areas looked like years and decades ago.

Importing KML to Google Maps. Google Earth Pro and Sentinel EO Browser.
|
|
 |
|
The part of this video demonstrates import KML/KMZ-file to Google Maps from different sources. It also demonstrates an example of limitations of Google Maps for remote areas, as well as how to get extra satellite data with Google Earth Pro and Sentinel EO Browser.

NASA WorldView - another source of remote sensing information
|
|
 |
|
The first part of this video is a lecture about using NASA WorldView portal. That's another source of satellite images updated every day.
