Hi, and thank you for the reply! I am using a developer account that has level 2 privileges and 45 available credits. I am not using a Portal/ArcGIS Enterprise account. Thanks again! Alin ... View more

Thanks! My rasters are in .jp2 format (JPEG 2000), so they should be compatible. I need to insert them both, as the functions applied only work like that. Alin ... View more

I did the full workflow again, and it works like that, but the main difficulty was to get it done with arcpy (Edit Raster Function—Data Management toolbox | ArcGIS for Desktop ), as I have many datasets like those. If I export the function chain as a template, it will refer to the same two mosaics, right? How can I make the template apply for any inputs? Thanks! Alin ... View more

I did this, but it only processes the Mosaic Dataset on which the function is applied: This is the raster function inserted. The first Mosaic Dataset is a one-band NDVI. I added the second one (Raster_Change_Detection_2_2) by browsing to the location on the GDB. The processing result is not correct. The function divides the values of the same first Mosaic Dataset, and I only get a value of 1, as below: Thank you very much! Alin ... View more

Thanks for the answer, Jake! I know about that section, but my problem is a little bit different. While I can insert raster functions to the separate rasters in the Footprint (say NDVI), I cannot create a general function (at the Mosaic Dataset level) that takes as input same rasters from the mosaic dataset and do an arithmetic operation for example. Below I attached screenshots of the mosaic, and the Arithmetic Function. These are the rasters inside the mosaic dataset. They are a separate 1-Band Mosaic Datasets of different years. (Crated with: Creating a mosaic dataset containing raster data from multiple dates—Help | ArcGIS for Desktop ) On them, I need to apply the difference "Raster_Change_Detection_1_1" / "Raster_Change_Detection_2_2" on-the-fly. If i go to the Mosaic Functions tab, I cannot choose those two rasters. Is there a way to do this? Suppose there is a way with raster functions, I can further use arcpy to automatically do this analysis. Thanks again! Alin ... View more

Thank you very much Cody. I will use the DRA stretch option as a raster function to automate my work. Regards, Alin ... View more

Thanks again.   Do you use the Dynamic Range Adjustment stretch as a raster function, or is there an option in the Mosaic Dataset's settings?   Alin ... View more

Hi Cody! Thanks for the reply. You cleared my misunderstandings of the Sentinel-2 MD toolbox. I hope the team will finish the update as soon as possible. Do you know of any problems regarding the  calculation of statistics for the resulting mosaic dataset? When I try to calculate the statistics, they do not get created, even if the tool runs without problems. Thanks a lot! Alin ... View more

ESA recently changed the product definition for Sentinel-2 data.The images now a in a single tile, opposed to multiple tiles as before, so many of the ArcGIS tools need to be upgraded as well. I tested the ArcGIS tool with the sample Sentinel-2 image (link: https://scihub.copernicus.eu/news/News00106 ), and I can no longer insert the Sentinel-2 image into the  mosaic dataset. On a side note, when I create a Sentinel-2 Mosaic Dataset with the tool, for an old format image, the 10m resolution MD does not have the Band  8 (IR) of the image, only the Bands 2, 3 and 4. The band 8 is also a 10 m image. ... View more
