Thank you, Prof.Wu. for the nice clarification. However, I can't observe the pixel values by using the inspector (i.e when I click it, I got the attribute error, just codes). Is there anyway I can look at the values?
Thank you for this video, prof. Wu. Please, where can I find the source code for the user_roi and inspector function? I'd like to know how did you manage to convert the drawings you create by ipyleaflet drawing control to be ee objects?
Hey Qiusheng. I am at 11:53 at this video, where you are showing how to search keyword "census" under data tab. However it gave me an error says: "'NoneType' object is not iterable". My ee, geemap all imported correctly, I have GEE credential set up. My geemap version is 0.8.13. Do you think it is a version issue (your video is 0.8.8) or where do you think I could've done wrong? Thanks in advance.
@@giswqs I tried but it didn't work. But I also tried same code on my other computer and it worked fine. It has something to do with my environment? Same thing happened before when I tried publish the geodemo package pypi website in your another video. Not sure why. Did you have similar issue with different computer?
Hey Zhaowei! Have u sloved the "'NoneType' object is not iterable" problem? I have met the same situation, could u please share some ways for me? Thanks a lot!
Dr.Wu, I like to start off by acknowledging how exceptional of a job you have done regarding both the geemap package and creating these valuable tutorials. I really appreciate you also take time and effort to explain things in such a simple way so people with little coding experience can understand it. Just have a question regarding the ee.featurecollection, what function/method would I be able to extract a property (a string corresponds to each feature in this case a polygon) of a shapefile and plot/add it right in the center of the feature (a polygon) of the same file? Ex: in the case of this video, how would you plot column 'Name' as a label in the center of each polygon
It seems possible through the ipyleaflet Popup widget. The downside is that the text size does not change according to zoom level. The map can look very crowded when too many labels are on the map ipyleaflet.readthedocs.io/en/latest/api_reference/popup.html
Hi Prof, Just noticed that functionalities like dataset search are not available when running geemap in google colab ! Is there any way to get the same kind of interface like in this video in google colab ?
Hey Qiusheng. I am trying to create a time lapse for my interested area using Map.user_roi, an area roughly 2 mile by 2 mile, and I am using imaging collection 'LANDSAT/LC08/C01/T1_SR'. However, the image quality is very blurry. Is there a way to obtain better (best) image quality using geemap? Is there an existing function that allows me to obtain monthly image within ee.ImageCollection.filterDate() function? Thanks much in advance.
@@giswqs Thank you! I saw the example you did for Aral Sea was pretty sharp. Does GEE provide higher resolution image other than Landsat 8 image collection?
Awesome tutorials. Time to customize some of the stuff to fit my projects. See you again in the next video!
Great Tutorial. However I could not find the 'data' file in your github account. Can you help me in this ?
github.com/gee-community/geemap
You are an amazing teacher, thanks Prof.Wu
Hello Dr, is the "data" fold removed or renamed as I can't get it.
Thanks.
Yes, is not there.
So nice job sir. Waiting for more such like GEE videos.
You are an excellent teacher. Thank you so much.

Try restarting the kernel

Yes, it is probably related to the conda env. Try creating a fresh conda env to install geemap.
@@giswqs Thanks much Qiusheng. Will try that!

You can use collection.aggregate_array("property_name") to extract attributes. Unfortunately, there is no way to plot them on the map yet.
This is also the potential workaround I was thinking about. The problem is that ipyleaflet does not seem to have a way to display text-only marker

The timelapse is created from 30-m Landsat imagery. Getting blurry timelapse for a small area s normal.
@@giswqs Thank you! I saw the example you did for Aral Sea was pretty sharp. Does GEE provide higher resolution image other than Landsat 8 image collection?
Aral Sea is a huge area. GEE has Sentinel-2 data with 10-m resolution available from 2015
hi Dr,Wu , I want to ask why there is no small button in the upper left corner of my geemap？
Are you using Colab? Try Jupyter
@@giswqs thanks for your reply ,but i used the jupyter😭
Dr. Wu: Why can't just type "states.Filter.inList()" ?
Because the Earth Engine API does not provide such a function.
