Dear David I thought I would provide some feedback - I have a workable solution! So I tried PTGui but the free version really has excessive watermarks, rendering it just about unusable. I share below a screengrab to demonstrate what I mean. I tried a few other free options but really liked Microsoft's Image Composite Editor although I understand it is no longer supported - but I was able to find the install file on the Internet. Equally important is sharing 360 pictures and I found kuula.co a be a great free option. It can handle quite large files (larger than some of the other options I tested), but when exporting images from the stitching software, I had to make sure that I set the maximum width to 16384px and then it loads and displays perfectly. Best wishes Mervyn

Hi Gorden I dont have a an image server but I can try ArcGIS Image for ArcGIS Online. Do you think it will work? Tile or dynamic imagery? I have just tried running the Video Multiplexer tool again using a DTM (32bit floating point) created using Drone2Map but that also failed. Pretty frustrating. Do you perhaps have any comment on the second part of my question around ensuring that the right elevation product (Airbus in my case) gets used when using the terrain service? Best wishes Mervyn

Hi there I am struggling with the Video Multiplexer tool. I am unable to use my own Digital Elevation Model as input. I have tried different formats (.tif & .crf) and projections but I always get the " ERROR 002650: Error extracting data from the provided elevation layer." error. Any suggestions as to what may be the problem? I am able to run the VM tool using the Living Atlas Terrain layer (https://elevation.arcgis.com/arcgis/services/WorldElevation/Terrain/ImageServer). I have a question around this too. This terrain service is made up of different data products. Some very coarse. How can I ensure that the Airbus World Dem 24m is being used when running this tool with the terrain image service? Should I be using the Make Image Server Layer to query for a specific product? Thank you. Regards Mervyn

Hi there Yesterday I tried capturing a 360 panorama image using the Panorama functionality available in teh Site Scan LE app. We want to use it for monitoring purposes as it is now easy to recapture the same image in a years time as the flight has been recorded. So flying the drone and taking the 28 images was easy, I just cant figure out how to now stitch the images to create the panorama image and then to view it. Are there any links to documentation or advice that anyone can give? Regards Mervyn

Hi there I used the SiteScan LE app and the grid flight pattern to capture 760 images using a DJI Phantom 4 Pro in a savanna (woodland) area. I am using Drone2Map to process the imagery and find that I am not entirely happy with the results. I initially just accepted the default settings (under Options and the 2D Products and Initial tabs), but have since tried changing some of these. I am particularly interested in creating a good DTM to assist with an erosion rehabilitation study. The two below images of my DTM and DSM show that these layers can still be improved. I would love to know what settings should I be changing to get the best output? Are there any best practices that anyone can share for processing imagery from areas that are quite homogenous? Processing time is not important. Thank you! Best wishes Mervyn

Hi Glen I have tested about 8 MMPKs that all failed. I am happy to share a few with you. Please provide me with a way to share them with you. Regards Mervyn

Hi Glen So I have done some more testing, with a Field Worker account this time, and it still crashes when trying to open a side-loaded MMPK. I did try downloading a few more MMPKs from AGOL and they all open successfully. And just to confirm that the same behavior (crashing when opening side loaded apps) is happening on both my Android phone and Android tablet. But not in ArcGIS Explorer which opens the side-loaded MMPKs on both devices. Phone specs: Samsung Galaxy A72 (model SM-A72F) running Android 11. Software update installed on the 4 July 2021! You may be onto something. Tablet specs: Galaxy Tab A (2016) with S Pen running Android 8.1.0. System software updated 1 July 2021. Best wishes Mervyn

I hope someone can help me. This is complicated. Until 3 July, my installation of Field Maps was working fine and I had many MMPKs and TPKs (for Basemaps) side loaded on my device. I had a Tracker for ArcGIS license issued to my Administrator user role. Then on the 5 July, as I was traveling into a remote area, suddenly the app would not open and it would get stuck on the opening blue screen (for hours). I tried uninstalling and reinstalling the but that would not work. The app would open, and one can download and open MMPKs, but as soon as I sideload a MMPK onto the device, then the app will crash and close when opening a side-loaded MMPK. I even tried using the latest beta version of the app, the side-loaded MMPK will open once, but thereafter the app wont open and it will get stuck on the opening blue screen and not progress past that. These MMPKs are ones that worked before, and they now work perfectly on the ArcGIS Explorer app (I am resorting back to my old friend), but not in Field Maps. Crashes every time I try to open them I have tried signing in with different AGOL accounts (I have access to 3, 1 without Tracker), but that doesn't change anything. I even tried installing and opening up a side-loaded MMPK on my Samsung tablet and that also crashed. Makes me think the error may be with my AGOL account, but why does the same thing happen when I sign in using a different account? Perhaps related, our AGOL organization account was renewed in July but our Tracker licenses were not immediately added. They are activated now but that does not change anything. I hope there may be an easy answer to this. Best wishes Mervyn

It sounds like it may be a problem with pyramids. Try running the Build Pyramids GP tool.

Dear Jana Thank you so much for the feedback. I have not worked with view tables as my data source is nearly always from standalone tables. Sorry I cant offer more advice. Best of luck getting your view tables converted to standalone tables.

Perhaps check the column headings in the table you want to join to a feature class. Try and make sure that none start with a number or have any unusual characters (%,$,#) in them.

Hi Jana The Add Join and then exporting to feature class or shapefile is working fine with me. The resulting table has all the attribute fields of the joined table. Perhaps try running the Join Field GP tool, which will add the new attribute fields to the existing Feature Class (you do not need to exp[prt to make a copy of it - if this is what you require). Or try re-running this process in a new map.
