In ArcMap everything works fine. The details of the spatial references I am using are attached below.

Thank you for your answer. I am not sure if I understand you correctly. I have tried to create from my string data a float data using Copy Raster function. However, still I have a message that my data are string. It is strange, because both (input and output) data which I used in copy raster function are float. ... View more

I think this is not the case, because after removing the quotes I cannot run the model at all, I have a message that the expression in raster calculator is wrong. ... View more

Thank you for your answer. I followed your idea, however I stocked in the last step - stretching the data. Below is my workflow which I implemented in model builder: 1. Iterate feature selection of my polygons using their ID 2. Clip the raster DEM using selected polygons 3. Get raster properties from my clipped DEM (minimum and maximum values) 4. Stretch the data using raster calculator expression: (("%DEM_%Value%.tif%"-(%Property%))*1)/(%Property (2)%-(%Property%)) where: %DEM_%Value%.tif% - input DEM and %Value% is the polygon ID %Property%  - minimum %Property (2)% - maximum After running my model I have the error (attached below) and I do not know why it does not work, because when I try to run it manually it works. Any ideas?

Okay, I understand. Thank you for detailed answer for my question. ... View more

Thank you for your answer. No, I do not want to embed it, because actually  it is currently embed in my story map, and I would like to have it now as standalone WebApp. ... View more

I did the pre-processing of my data twice: once using Spatial Analyst Tools > hydrology, and second time by using tools available in ArcHydro. I still have the same error. ... View more
