collect earth grid generator doesn't give grid data

Question

Hello,

When I use collect earth grid generator, when I click on “click to download grid” I am redirected to the open foris page. I cannot get the grids.

Could you please help me?

Thank you!

Thanks for reporting the issue!

I am trying to reproduce it but so dar the tests that I am running are working. Here is for instance the link to the Grid Generator that includes the parameters for generating the grid over a province in Turkey, which works fine : https://collectearth.users.earthengine.app/view/collect-earth-grid-generator#LEVEL1=Turkey;LEVEL2=Adana;LEVEL3=;GEOMETRY=;DISTANCE=1000;

Would you be able to share here the link with the parameters that you are using for the grid generation? You can see that when you set the parameters in the Grid Generator tool, the URL in the browser changes. You can send that URL for us to test.

Looking forward to your feedback!

Hello.

Thank you very much for your quick response.

I am doing the experiment for all turkey and when I click the link you sent, I also see the “select distrinct” button and it works through the link you sent. However, when I go to the grid generator via google myself, I cannot see the “select distrinct” button. I can only select whole countries and when I click the “click to download grid” button in this way, it redirects to the open foris page.

I am forwarding the link: https://collectearth.users.earthengine.app/view/collect-earth-grid-generator#LEVEL1=Turkey;LEVEL2=Whole%20country;LEVEL3=;GEOMETRY=;DISTANCE=5000000;

note : The distance is currently for experimentation and quick results.

To select a province you need to choose it from the second selection box (where it now says Whole Country ) After you select a country the menu with the districts will appear.

I think the problem for this grid generation for all of Turkey that you are having might be related to too many plots in the grid. If you limit it to one province it will work.

We were look into how to fix the issue so that the grid for Turkey can also be generated as it should be no problem. In fact when you select to generate the grid without the extra information (Admin units, Elevation and so on) it does work, but in any case this needs to be fixed https://collectearth.users.earthengine.app/view/collect-earth-grid-generator#LEVEL1=Turkey;LEVEL2=Whole%20country;LEVEL3=Whole%20province;GEOMETRY=;DISTANCE=5000;ADDIPCC=false;ADDGAUL=false;ADDDEM=false;

Hello, thank you for your return.

I should do this for the whole turkey without selecting the province and I should select additional information (such as IPCC data, Dem Data).

Is it possible to fix this?

By the way, when I change the distance in the last link you sent or when I open the grid generator directly myself and use different distances for the whole country without including additional data, I get an error again.

edit : I get the same error when I draw an area to cover Turkey. I hope it will be solved as soon as possible

Hello, I think there is a problem with the number of points. We want to throw a systematic point for the whole turkey and it gives an error when we try 5000m and below. but it works when we select much larger distances. could this be due to a decrease in the number of points? Could it be a limitation related to the data limitation of GEE?
