How to compare the data before and after augmentation using prepare_data

lienpham83

Hi,

I use the arcgis.learn.prepare_data for data augmentation. Then, I use show_batch to visualize the exported training samples with labels after data augmentation. However, I do not know the coordinate location of the samples on the raster imagery. How can I know this coordinate information of the samples along with labels? The reason I need to know the coordinate locations of the samples is to examine the changes of samples after applying data augmentation to choose suitable augmentation parameters.

Thank you.

Currently we do not have any way to know what coordinates you are looking at from the {data}.show_batch() output.
However to address your original concern you can call the prepare_data() by passing an additional parameter transforms=False, this will turn off all kind of data augmentations. You can then visualize sample data using {data}.show_batch() and compare it with the ones you get without passing this parameter.
