What year? for both the training and test datasets?

This dataset is highly implicitly described. Unclear to some like myself and gives me (us) an undue disadvantage in making my (our) hands dirty.

Can the admin clarify it? I feel the data is poorly described and needs a better presentation for us all to participate actively.

Thanks for the query.

Data for Afghanistan, both for training and testing were collected between 1 and 30 April 2022.

Thanks .... then the right time range is

• Afghanistan

Training: 2022-04-01 ==> 2022-04-30

Testing: 2022-04-01 ==> 2022-04-30

• Iran and Sudan

Training: 2019-07-01 ==> 2020-06-30

Testing: 2022-07-01 ==> 2023-06-30

Hey @Lolletti and @Zindi team,

Can we confirm @HungryLearner's conclusions to ensure we're on the same page? Understanding the dataset's date ranges is challenging, and given the nature of the data, it's time-consuming to acquire. It would be a time-saver for all of us.

Hey @Zindi, @amyflorida626,

There is a new discovery about the dataset from @Lolletti comments that "Data for Afghanistan, both for training and testing were collected between 1 and 30 April 2022." So we are now sure that for afghan, we are NOT GOING BEYOND 2022 for both training and testing and the month is strictly April and NO MAY.

Is it possible to now have the following phrases edited accordingly or else provide clarification to clear my misconception?

• in evaluation section

a) For Afghanistan (Nangarhar province): temporal cropland extent distribution of May in both 2022 and 2023.

• in data section:

2. Training samples: ..Particularly, for the cropland mapping in Afghanistan, only training samples collected in 2022 can be used to train the classification model, and the model is then used to identify cropland extent in 2023.

Please also help clarify this conclusion for sudan and iran:

Training: 2019-07-01 ==> 2020-06-30

Testing: 2022-07-01 ==> 2023-06-30

Hi, thanks for your question. It was considered an issue uploading datasets for 2 years in Afghanistan within the same .csv, since it might have caused confusion. Therefore, only 2022 data were considered. The sentence in the evaluation and data sections will be amended accordingly.

Data for Afghanistan are ALL (both train and test) collected between 1 and 30 April 2022.

@Lolletti can you also clarify the dates (both train and test) for Sudan and Iran?

Hi, for Iran and Sudan please stick with what was explained in the info: July 2019 - June 2020.

Thanks @Lolletti for reply. so final clarification, does it mean for BOTH TRAIN AND TESTING for SUDAN and IRAN we stick to July 2019 - June 2020?

For Afghan, it is so clear now , thanks to you @Lolletti for clarification. For IRAN/SUDAN we are still stuck on the TRAIN/TEST period (s). Is is it same period -July 2019 - June 2020? You have'nt said clearly, but for afghan you have clearly repeated, so no doubt now.

@lolletti, I hope this one is fine now. Please comment on the two sections and not only on one. Thanks

• Afghanistan

Training & Testing: 2022-04-01 ==> 2022-04-30

• Iran and Sudan

Training & Testing: 2019-07-01 ==> 2020-06-30

Is this what we should use @everyone here in this challenge

Yes... based on the last confirmation by host up to this point

Thank you
