Glad you found a way. Both should work. Copy Raster will take the raster layer created from your processing chain as input. Generate Raster From Raster Function takes the .rft as input.

Not only can you view raster function processing result on screen, but also persist the processing result as a raster dataset on disk including the file geodatabase. After you have the processed layer, use Copy Raster Geoprocessing tool to save the result, it can be geodatabase, it can also be other formats like TIFF or CRF. Hope this helps.

Hello @MAHMOUDBENDALOUM , Regarding the two geo processing tools, they work very similarly for common cases, the major differences are Clip Raster tool now works with multidimensional raster. if you work with scientific data that is multidimensional raster, the Clip tool can maintain the dimensionality. The requires difference licenses. Clip Raster is a tool requires ArcGIS Basic license, while Extract by Mask tool requires Spatial Analyst extension license. Hope this helps.

Did you have Image Analyst Extension license enabled? LandTrendr algorithm requires Image Analyst license.

Hi Yuhang, could you check two things? I noticed there is a space in the extension of the output file name (. crf), could you check whether that is the cause? I also noticed that you were running on a machine of Chinese operating system, would it possible to try on a machine of English operating system?

please see this blog on creating a multidimensional netCDF from tiff files https://www.esri.com/arcgis-blog/products/arcgis-pro/imagery/create-multidimensional-raster-data/

Hi Tilmann, Thank you for providing the detail information on the problem. The bug has been reproduced and logged. We will make a fix and release it as soon as possible, please track the status using this number BUG-000135547. The workaround for now: use Make Multidimensional Layer to select one variable and use Sample tool with one variable as a time. Regards, Hong

Hi Sara, sorry for the late reply. we made some fix in 2.6 and confirmed with S5P_OFFL_L2__NO2, S5P_RPRO_L2_NO2, S5P_NRTI_L2_NO2 products, please check out when 2.6 is released. Thanks, Hong

Hi George, Peter is correct. You do not need to use Ortho Mapping if you only want to orthorectify one satellite scene. But you have GCP data and want to improve the geometric accuracy before orthorectify, you can use Ortho Mapping. The steps are 1. create an ortho mapping workspace and set your better DEM in the data loader option 2. since you only have one image, you can skip the Adjust tool and using GCP manager to import your GCPs and measure the corresponding tie points 3. Then you run Adjust tool 4. To save an output, you can use the the custom product wizard, and with only the last option on and set the output pixel size and format. you can also provide your good DEM here if you didn't use when you create ortho mapping workspace Hope that helps. Please let us know if you have different scenario.

Adam, The camera report you included does not have radial distances, but these can be calculated from the field angles using this formula: distance = focal length * tan(field angle) The values for the fields can be set as below and the unit is um. 20169.95;41051.42;63460;88453.53;107276;128555.1 for RadialDistances -4;-7;-7;-1;3;4 for RadialDistortions you can actually avoid the hassle using the user-friendly wizard by clicking the "+" button next to the camera, and fill in the distortion table as below Hope this helps, Hong Xu

Right, the advantage of netCDF is that it stores multidimensional rasters with multiple variables in it, and the mosaic dataset model can be used to manage these multidimensional data in netCDF. You can display any available of any time or vertical dimension. please follow this help to prepare your mosaic dataset. After created, the mosaic dataset will contain the variables you add , and each variable will have a corresponding variable selector template. In ArcGIS Pro (assuming you use Pro, it is also supported in ArcMap), you can use the raster function template button (accessible from the mosaic dataset contextual tab) to display each variable The image service published from it will also have the same set of processing templates, and you can access in the same way as mosaic dataset from Pro. In web map, these variables can be accessed from the image service layer -> context menu->Image Display, then choose the corresponding template. Hope this helps

Hi Larry, Without knowing the detail of your local datum, I tried using this case: UTM (WGS84 datum) as the projection of the mosaic dataset and NAD27 and NAD83 as datum for the images that will be loaded to the mosaic dataset. 1. create a mosaic dataset with UTM projection and add datum transformations from the GP environment setting for transformation between WGS84 and NAD27 and WGS84 and NAD83, there are many options that are available, but make sure that you pick one that is suitable for your data 2. add the images to the mosaic dataset. This should be done. when accessing the mosaic dataset (the images in the mosaic dataset), the system will pick the corresponding transformation to use. when you comparing with ArccMap, please make sure that they are using the same transformation (ArcMap default may not be the one that you pick from the environment setting). If you still see issue or issue with your data, please contact Esri support with your data to reproduce. Regards, Hong Xu

Hi Jessica, Creating ortho mapping workspace requires both image geolocation and camera information. One of the possibilities that I can think of is some of the parameters are missing or not defined with expected unit? If this does not solve the problem, please contact technical support with a small set of simple data, we will help you out. Regards, Hong Xu

The Pro Ortho Mapping App is built on top of Geoprocessing tools and mosaic dataset data model. But from the error message, it seems that you didn't define your camera parameters properly. Creating mosaic dataset outside of Ortho Mapping App might not help. I suggest that you make sure that the camera parameters are correct (the units for focal length, pixel size, and principal point are all in millimeters), if it still does not work, please send your data to technical support and we can investigate. In case you are interested in building mosaic dataset manually using geoprocessing tools, here are the steps To create a mosaic dataset from your drone images, you may use: Use Create Mosaic Dataset too to create a mosaic dataset Use Add Rasters to Mosaic Dataset tool and use UAV raster type to add your drone images to the mosaic. Please note, in Pro 1.4 release, the mosaic dataset created in outside of Ortho Mapping App will not be able to import to ortho mapping workspace (this will be enhanced in future release). you can use Compute Camera Model GP tool to do further processing. Hope this helps Hong Xu, team raster

ArcGIS Pro 1.4 currently does not support yaw, pitch, roll for camera orientation. However for drone images, these parameters are not required. if not available, as many drone images do, camera orientation will be computed automatically during adjustment process. Hong Xu, team raster.
