after doing the selection, when I try to add the selected states or the clipped dem as a layer, I always get this error : {EEException: Collection.geometry: Unable to perform this geometry operation. Please specify a non-zero error margin.}
Hi, these videos have been really useful! I was just wondering; is there an easy way to clip an ImageCollection in the same way you can clip Images? I've been trying to clip MODIS data to a buffer I have drawn on the map, but as the 'clip' function is only available for Images I haven't figured it out yet. Thanks for all your work!
Dr. Wu. I am wondering if it’s possible to export these points with their lat lon location, so that the Shapefile can be used to request data from other APIs?
I want to create study areas of 5 km diameter circle by making GPS coordinate in the center in google earth engine. Could you help me please where and how can I learn it
After running import geemap / Map = geemap.Map()/ Map ...it doesnt generates the map, so the Map.draw_features produces an error. Any advice? I am in google colab. Thanks in advance.
Google Colab currently does not support ipyleaflet. Therefore, the ipyleaflet-based geemap won't be work on Colab. I would encourage you to install geemap on your local computer. You can also try binder, but be aware of the security risks github.com/giswqs/geemap/issues/2#issuecomment-609795905 binder: binder.pangeo.io/v2/gh/giswqs/geemap/master?filepath=examples%2Fnotebooks%2Fbasemaps.ipynb
"Collection.geometry: Unable to perform this geometry operation. Please specify a non-zero error margin." I encountered this error while adding selected states to the map (variable 'm'): " m.addLayer(selected_dist,{},'selected districts')". What could be the possible remedy of this error?
The geemap package is designed to work with Jupyter notebook. I have not tested it with PyCharm. You should be able to `import ee` with PyCharm, but I am not sure about `import geemap`.
@@giswqs Thanks sir for your response to me, yes sir, you are right, i have already import geemap in pycharm but it is not working in IDE but same code works fine in Jupyter. so can i do anything/ big tasks related to google earth/remote sensing in jupyter?
Hello Prof. Wu, I am currently watching all your videos one by one. I am more familiar with GEE javascript API. For my interest and help college professors in India, I wish to develop a series of simple web apps. Such as explore monthly NDVI or NDWI. I have a few UI made in Javascript (Also from GEE examples) What would your advice regarding how to use Python in developing such apps for teaching purposes? This is what I made using Gena's and GEE example - code.earthengine.google.com/11fdca705060d8914313f8bc8ad023d9 . It would be nice if I could develop more to specific needs to those teachers who don't have a coding background. Could you please guide me on how to start. Thank you very much
Thanks, prof. Wu for your efforts! Greetings from Egypt
Thank you very much for this class! it is very informational and really useful for a new learner!
Thanks a lot Wu, for your work and share it! greetings from Ecuador
This was really helpful. Thank you.
You are a piece of art. TKS!
Thank you, very useful! Exited to use the GEE in python for my next projects!
Great Job! Dr WU
This was fantastic, thank you!
太棒了

You can use the map function to achieve this. Check developers.google.com/earth-engine/ic_mapping
@@giswqs Great, thank you so much for getting back to me!

Python: points.map(lambda x: x.buffer(5000))
i have a set of coordinates with me , what should be the syntax to create a polygon from them
Try mygeodata.cloud/converter/csv-to-shp
Also developers.google.com/earth-engine/geometries
Sir, how to get length of a polyline? I can't use function such as length() to get.

What drawing tools did you use? Try a rectangle or polygon
@@giswqs thank you for the response.
It works for rectangle and polygon but not for circle. Why is it so?
Circle works fine as well. See i.imgur.com/tviYAKt.png
Sir , I can import map in jupyter but how to import earth engine map in pycharm IDE?

Yes, you can. That’s what Earth Engine is good at
sir,
AttributeError: 'ImageCollection' object has no attribute 'clip'
Please share your code for debugging
@@giswqs Thanks sir . I solved it using pip install in anaconda environment. It is working fine .

Try out Earth Engine Apps: developers.google.com/earth-engine/apps.
If you use Python, coding would be hard to avoid.
