In this course we will discuss fundamentals of air- and space-based remote sensing applied to geological and environmental problems. The core goal is to understand how different wavelengths of electromagnetic radiation interact with Earth's surface, and how images collected in these different wavelengths can be used to address questions in the Earth sciences. Lectures will present theory and basics of data collection as well as applications in hydrology, vegetation analysis, glaciology, tectonics, meteorology, oceanography, planetary exploration, and resource exploration. Labs will focus on commonly-used imagery and software to learn techniques for digital image processing, analysis and interpretation in Earth science.
Thank you for this. replicated this but got "ERROR 010658: Failure in distributed raster analytics operation" when I ran the nibble tool. what could be the problem
hello sir , i am a student from Bhutan and doing a research on a quality of water with qgis without doing experiment so i am stuck how to generate graph like sir , is it from the data by remote sensing or the experimental data, it will be grateful if sir could help me
Great tips! Thanks for the workflow. I would just add that one could benefit more from the resulting info by editing the raster's symbology depending on the value range. The Contrast raster, for example, might have the majority of its values no greater than 3 but the few outliers with a value of 15 results in a raster with seemingly little detail. The histogram again is a good tool to find the sweet spot for the min and max values one should have.
Let me ask you a question. Let's assume that you are under Polaris, and as soon as you start walking away, measure your angle of elevation and distance between you and your starting point. Now, at what degree do you start taking into account the magnetic molten center of hell?
But when the reference surface is NOT flat! But have a difficult terrain! That mean your surface contain hundreds or thousands of different heights How can i do that!?
Its very very informative video. I would like to say thanks to creator. And will add 1 thing. The file path would not amended in command directly rather we have to right it in notepad and then copy to command
This video was incredibly helpful for my thesis! I had to clean up my raster data showing where puddles form after rain by subtracting a fill raster from the original height map. The resulting data had a massive amount of noise from single and small pixel clusters. These steps made the data a lot more useful and digestible!
