- This guided project is part of the End-to-End Google Earth Engine course offered by Spatial Thoughts. spatialthoughts.com/courses/g...
This series of videos will take you through the entire process of building a script for visualizing and mapping floods using Sentinel-1 dataset.
Get the code from code.earthengine.google.com/?... - Наука
thank you sir, very useful
Thank you for sharing the video and the script. I used the later to prepare my own script to export an S1 SAR image of the Sikkim region, mainly to identify the glacial lakes. Landsat 8 images were not good enough to detect them in the visible spectrum.
good evening to you trainer, please I have a problem when I type on the line '24' the following request:
".select(['HV', 'HH'])"
in the console there is nothing it says "NULL" I do not know why!!!!
sir, how can we use ostu thresholding techniques to determine optimum thresholding technique and VV polarisation to determine flood inundation mapping? can i have the code for that?
how to get the autocompletion command in the script editor. When you want to type the .filter, automatically it is showing for you what is the shortcut you used?
Code editor has smart autocomplete, use 'Ctrl+Space' to autocomplete API functions and the same combination agian to autofill all parameters.
Please on the line 17, var filtered what? It's not really clear please. There is a letter at the end of the filtered which isn't really clear
Sir, I tried do it for my area of Interest (Maharashtra). But I am getting error. Could you please tell me what should I want to change in that code for my region. Thank you in advance sir.
You need to share your code. See instructions at courses.spatialthoughts.com/end-to-end-gee.html#sharing-a-single-script. Paste the code link and I will take a look.
sir i am getting null printed while executing the first part
Depending on the location, you will have to use ASCENDING or DESCENDING orbit. Also adjust the date ranges so there is al least 1 image. Due to failure of one of the Sentinels satellites, the revisit time has doubled.
