to both Julio and George Did you confirm if your TIFF file properties were set to read only?  I recommend this, to ensure the georeferencing is written to external files.   If either of you are still testing or need this, please let us know if this resolves the problem. Cody B ... View more

Abraham, I apologize for the long delay - I did not see your original post.  For both you and James: There is no formal limit, but yes there are practical limits.  For full processing (to create outputs such as orthomosaic, point cloud, etc.) I typically recommend a maximum of 2000 images, but this will depend on many issues - your processing hardware, as well as the individual image size in pixels, the amount of overlap, and the geography e.g. the content of your imagery (natural vs. man made terrain, presence of tall trees, etc.), terrain, etc..    System requirements are listed at https://doc.arcgis.com/en/drone2map/get-started/system-requirements.htm   For scaling up to larger projects, you have several options:   If you have good overlap between images (~70% or greater) you can reduce memory used by reducing the targeted number of keypoints per image. (Default is 10,000)  If you have ArcGIS Pro, you can to disable the outputs and create only the dynamic mosaic, then you can work with that (mosaic dataset) in ArcGIS Pro.  If you need to generate the 2D outputs from Drone2Map (orthomosaic, DSM, DTM), you can use the “Manage” menu to disable merging of tiles. This will generate multiple tiles for the outputs but not merge them into a single large TIF file.  [See reference in Help here]   Drone2Map will reference the multiple tiles in a mosaic dataset that you can view by using the “Add Data” button (or if you have ArcGIS Pro you can create a mosaic dataset to combine the tiles).  Look in the project geodatabase for a mosaic dataset named "OrthomosaicTiles" (or "DSMTiles" or "DTMTiles" as appropriate)           If these options don’t work, you may need to process your project in subsets. Let us know your results.  Cody B  ... View more

Ke Xu I will help but I need more information.  Are you using ArcGIS Pro 2.6.2?    You said the mosaic dataset was created, but this error sounds like it was not complete - am I correct that this error occurred when creating the OM Workspace?  And it mentions RPC, so I assume this is satellite data?  Was your satellite listed under Sensor Type?

Julio Can you provide more information?   confirm you're on ArcMap 10.7.1? confirm  you have several hundred tiff files you've manually georeferenced, and you used "save" to create *.aux.xml files for each image (not "save as" to write a new image file) can you check to see if the tiff files are read only and you do have *.aux.xml files?  If not, the transform may have been written into the tiff header rather than a sidecar file... when you say they "lost" their georeferencing I assume you mean you *do* have the  *.aux.xml files but they're not working properly?  (not that the sidecar files were lost) when you say " about 50% of the time" do you mean if you add 10 files into the map, 5 are correct and the other 5 are misplaced?  are they moved to (lat,long)=(0,0)?  some other random location?  when they move incorrectly are they aligned correctly relative to each other, on another part of earth?  Or are they out in space (outside the entire earth coordinate system)? when you see an image misplaced, do you still see it's previous tie points or are they lost?  Do you add new tie points, hit " Update Georeferencing", but they still go to the wrong location?  Is it a NEW incorrect location or they stay at the incorrect location where they initially load? Do you know if they all use the same transform (e.g. 1st order polynomial)? or could some be first order, some second order, some using spline?  Can you send us some of the *.aux.xml files?  (We may not need the tiffs)    thanks Cody B.  ...

Thomas Please wait a day or two - I will get back to you as soon as I can. I appreciate the response from Guenter, and those materials he referenced were our best workflows from a few years ago, but Ortho Mapping in Pro has improved much more as of version 2.6. When you say "no fiducials" do you mean that you have digital files but the fiducials are not visible? And can you tell me how many photos you have to process?  Cody B.  ... View more

Mattias sorry I haven't had time to work with you on this.  We may need to set up a meeting to discuss details and your objectives (short term and long term).   To start, I would need to be sure what "oblique viewer" you mean.  If you're building a Javascript 3x app using this widget ObliqueViewer | API Reference | ArcGIS API for JavaScript 3.33  and Web AppBuilder, note that the focus for the development team is JS 4 in the new Experience Builder.  So if this is something you need for long term, we should work in JS 4, but I don't believe an oblique viewer widget exists at this time.  Another key issue is serving the imagery.  If you're seeking to use the image coordinate system (ICS) and share a mosaic dataset with the images using the frame camera raster type, you'll need ArcGIS Image Server.  (Perhaps you already know that?). The mosaic dataset that you need is created directly in Drone2Map - the "dynamic mosaic" added in Drone2Map version 2.0 is configured for this purpose (e.g. to use on Image Server to access images using ICS, or to use locally in Pro for viewing in ICS or for stereo viewing with the Image Analyst extension).  Note you and I had a previous conversation (May 2019) about the sample script at http://esriurl.com/D2Mmanagement which will also create and configure a mosaic dataset, but as of v2.x this  mosaic dataset is created by Drone2Map. Could you send me an email to discuss? Cody B.  ... View more

We have been considering creation of an Android version, but note that this app is responsible for controlling and ensuring the safe flight of commercial drones, and this requires extensive testing.  Extending this functionality to Android devices would be a major development effort and we have not yet made a commitment to proceed.  Can you let us know your reasons for this request?  Is the primary concern related to the cost of the tablet?  Do you need a ruggedized mobile device?  Are there limitations imposed by your IT department?  Are there security concerns?  [Please add any other issues for consideration]   If you'd like to discuss your requirements further, please contact cbenkelman@esri.com ...

Mattias Presuming that you have interior and exterior orientation data in another format, this geoprocessing tool is designed to create the tables needed by ArcGIS Pro: Build Frames and Cameras Tables Tool—ArcGIS Pro | Documentation  If you don't have the  interior and exterior orientation data, generating that orientation data is a different challenge.  Ortho Mapping in ArcGIS Pro (Advance license) can also do this automatically as long as the oblique orientation is not too extreme (closer to nadir, not aimed at horizon), and it will directly create a mosaic dataset for you (you don't need to create the two tables). If you don't have ArcGIS Pro Advance license Yes, Drone2Map or Pix4D can create the  interior and exterior orientation data   Cody B. ... View more
