[@malcolmafonso1353]

Thanks buddy. I was just starting to explore GEE plugin for QGIS and this happens to be a good start. Cheers!!!!

[@burdGIS]

Glad it helped!

[@ewanharris5433]

Excellent Thanks from South Africa

[@burdGIS]

Glad it helped you Ewan

[@aliakbaramirkhani3265]

earth engine project is a brilliant project that Google company publicize it and that plugin did a great job by connecting QGIS and GEE together :D thx for share this video .

[@burdGIS]

No problem. Thank the developers, I'm just the messenger 😀

[@t0mmy-Sun]

love you so much!! high quality contents

[@burdGIS]

Thank you! 🙂

[@spatialnasir]

Great video. I like how you are teaching us how to use the docs.

[@burdGIS]

It's where you find all the best tips 😀

[@charlesphilip2094]

Thanks you so much you videos are very educative simple and straight forward

[@burdGIS]

Thanks Charles! I'm glad it was useful

Thanks a lot for making this video! :-)

[@burdGIS]

Thanks for making the plugin! 🙂

You videos are extremely good and useful. Thank you for the videos and your effort. Could you please put up a tutorial for river basin delineation in QGIS using HydroSHEDS dataset and Sentinel-1 ? How to calculate MNDWI in Sentinel-1 and 2 (In Sentinel-2, the concerned bands have different resolution). Your channel will be the first to show how to integrate EE/QGIS/Python for hydrology.

[@burdGIS]

Thanks deeps. It sounds like you have the workflow planned out. Have you tried this yourself? Where are you having problems?

[@divyasrini1]

@@burdGIS I am a CS professional venturing into the geo spatial world. I taught myself QGIS during the lockdown. I recently came across Earth Engine and became very interested in it. While looking for tutorials/slides, I came across your youtube channel. The whole world of RS is new to me and is a bit of a steep learning curve, along with GEE! But, I am inching my way forward. I thought of delineating a river basin. I was able to make progress using Sentinel 2 and NDWI. But don't understand how to calculate MNDWI. My goal is to export the image to QGIS and do the delineation there. I understand that you need a DEM. I don't understand how to use it with HydroSHEDS and Sentinel 2. I was therefore looking and hoping for some tutorials on this - start with EE and finish in QGIS.

[@divyasrini1]

I could share my EE code (with Sentinel 2 only) with you.

[@burdGIS]

Please do! Is it in javascript?

[@divyasrini1]

@@burdGIS Yes. Email id?

[@terencedodge3249]

I think it would have helped in the description and the voice over if we the end user knew we had to have a google earth engine specific account so as not find this exercise awkward or is that part of a subliminal test of the users?

[@burdGIS]

Thanks for the suggestion Terence. I'm glad you worked it out. More subliminal tests to follow :-)

[@burdGIS]

Thanks Moses. Including the log was veyr helpful. I haven't had a chance to test this on a Mac which I see you're using. However, there looks to be an issue raised here: github.com/gee-community/qgis-earthengine-plugin/issues/39 Please try the solutions there and let me know how you get on.

[@moseskolleh]

If you could find a solution for it I would be much appreciative. Thanks very much for the timely reply

[@burdGIS]

Hi Moses, have you tried any of the solutions in the issues link I posted? I'm afraid I don't have access to a Mac and will not have for... who knows how long at the moment.

[@moseskolleh]

burdGIS I have tried all the solutions mentioned but none of them work. It is still giving me the same error and I don’t know why.

[@solomonamankwahobiriyeboah2665]

@@moseskolleh I had the same problem. I'm using QGIS version 3.12.2. This is what I did to fix it. I made sure my python default is set to version 3.6.0 since the plugin works with that. I did that with "PYENV". After that, I navigated to the folder with the "credentials" file, duplicated the file, deleted the original, and renamed the duplicate to the exact filename of the original file. And that was it. Please make sure you have an account with google earth engine first and be sure the account is active before trying it in QGIS. All the best.

I keep getting an error that starts with "Couldn't load plugin 'ee_plugin' due to an error when calling its classFactory() method ", any help video on fixing this?

[@burdGIS]

Thanks G. What version of Q, the ee plugin and operating system / machine are you using? Have you checked the github issues page to see if anyone else has this issue? Have you tried reinstalling the plugin on different versions of QGIS? Let me know how you get on! :-)

@@burdGIS Using a 64bit windows 10, QGIS versions 3.141-1 and 3.14.15-1, and tried reinstalling plugin multiple time for each version.

I will take a closer look at github and see if I can find a clearer solution. Thanks for quick replay.

No problem G. Can you point me in the direction of some of the "tech language" answers you've found already? I might be able to help decode it ;-)

[@garryrobinson8091]

@@burdGIS First I found this post which I think is the same (similar) problem. github.com/gee-community/qgis-earthengine-plugin/issues/51. My error a bit different as I dont ever get the the "paste the authentication code into the verification box" step, the top line in my error states "TypeError: get_authorization_url() missing 1 required positional argument: 'code_challenge'" so I assume it something to do with authorization, so I clicked on the link in the above post, github.com/gee-community/qgis-earthengine-plugin#faq, and now I am completely lost. Just so you know I do have have google earth pro installed and working on my computer (so I do have an account set up). Basically I get lost when I need to deal with scripts and such. Thanks.

[@burdGIS]

Thanks G. Google Earth Pro and Google Earth Engine are different. You will need a specific Google Earth Engine account for this plugin to work. You should be able to sign up here: earthengine.google.com/new_signup/

[@Agronomistapolo]

Someone know why the icon identify features does not work in qgis with the plugin earth engine?

[@burdGIS]

The plugin works by bringing in a wms of the data. This really just shows the colour rather than the actual values. (AFAIK)

[@Agronomistapolo]

@@burdGIS Thank you. That sounds logic. Another question, Do you know why I can Export a Geotif to my Drive from Qgis using the plugin? I used the following code: ### export all features in a FeatureCollection as one file taskParams = { 'driveFolder': 'CCRRDonana_2020', 'fileFormat': 'CSV' # CSV, KMZ, GeoJSON } task = ee.batch.Export.table.toDrive(ndvi_15_mean, 'ndvi_15_mean', **taskParams) task.start() But not happen nothing in drive and any errors is shown. Thanks in advance

[@burdGIS]

Although it works of the python earth engine API I'm not sure all commands will work. Is there any mention of saving to drive on the plugin page?

[@user-mw4ij8re8o]

Hi! I was wondering if there's a way to load an image collection. For example, I need to load 1 year of Sentinel imagery for one tile to get the reflectance values from certain points. I find it easier sampling the points using QGIS rather than coding in GEE, but when I try adding the image collection (with all the necessary filters aplied) I only get one gray polygon of the corresponding tile.

[@burdGIS]

Thanks for the question Carlos. Can you share the code you have so far?
