Export Training Data For Deep Learning from Raster Mosaic dataset

Hi Folks,

I am trying to create training data set for deep learning, using "Export Training Data For Deep Learning" tool.

  • Input raster - i am giving in this tool is Raster Mosaic Dataset (created by referencing tiff images located at location in my machine). This mosaic dataset in created inside FileGeodatabase.
  • Input Feature Class - is polygon feature class - which has building footprints.
  • Output image format - TIFF
  • Meatadata format - PASCAL Visual Object Classes.

This tool run successful without any error. at output folder location it creates following folder structure also,

  • images
  • labels
  • esri_model_definition.emd
  • esri_tile_lines.json
  • stats.txt

But there are images inside 'images' folder and there are no xml files inside 'labels' folder.

Where as in other scenario, where If i give input Raster - as single tif file. it works properly, and creates image chips and labels.

What might be the reason? doesn't this tool support Mosaic Dataset ? 

I have large areas, so i mosaic-ed the images and then i am trying to create training data set. Do i have to run this tool multiple times for multiple raster images?

Hi Ravindra , As Dan mentioned Mosaic Dataset is a valid input to the tool and it does work. Can you tell me more about the specific version you are using and well as the data you are using.

Thanks Dan Patterson and Sangeet Mathew  for your response. I appreciate that.

It's not working for me.may be i am doing something wrong while creating mosaic dataset.

  • I am using ArcGIS Pro 2.3.3.
  • I downloaded images(15 images) and building footprints from Ordinance Survey, for UK Location. these images are freely available.
    • Original downloaded images were in ECW formats. So converted them into .tif. and then made mosaic dataset. after this i am trying to create training dataset using this mosaic dataset.
    • But i am able to create training dataset from individual .tif files. since i have 15 images, so i thought to mosaic them, into one, then at one go i would create training dataset, but it did not succeed.
    • When I create training dataset from individual .tif files, it will generate into 15 diff folder, so then later if i want to combine all training dataset into one, naming convention and their meta data i will have to manually do it.
  • Projection - 27700.prj used. there was no projection defined to images and vector data. so i defined the projection from Define_Projection tool.

If there is anything wrong here, in my process, please point me to correct one.

there was no projection defined to images and vector data. so i defined the projection from Define_Projection tool.

I hope that they were in that coordinate system.

Using the Define Projection tool should only be used if the data you are working with is just missing a known coordinate system. 

If the data were in a different coordinate system and this tool were used with the wrong definition, then the data would be wrong/useless.

Check that step to confirm that Define Projection was used appropriately.  If you need it in a different coordinate system, use the Project Tool

Along with downloaded data, it was mentioned that the projection is 27700 projection

i am sure about this.

I have a question about the output from the Export Training Data for Deep Learning - what should be in the "labels" folder? I have .tif and .tifw files in my "images" folder. But my "labels" folder has .tif, .tifw, and .tif.aux.xml files - the .tif files are all black - no image shows.

What should be in this "labels" folder? Thanks

I am having a similar issue with the all black .tif files, and errant results from the model "trained" on these images.

@DavidHarris5, were you able to solve the the issue with all black .tif files in your exported mask? I am having same issue.
