Hello Gareth, @GWaltersOZ GeoTriggers has made a come back. In the latest version of the Runtime you can now build geotriggers which provide the Geofencing capability you are after. Thsi blog provides the detail. FieldMaps does not have the capbility today but it is on the roadmap Cheers Gordon

Mervyn, If the DTM from D2M is also failing I wouls suggest a support call. In regards to the elevation in ArcGIS Online I would try a Hosted Elevation layer first and if that does not work then I would try an image service in ArcGIS Online. Either formats should work. Gordon

Mervyn, Definately an odd issue seeing how the Esri Terrain layer works. I can see two things here 1) The Esri terrain is an Image Web Service. Do you have the capacity to publish your elevation source as an Esri Elvation image source? If so try that. 2) Log this one with support. It technically should work if your elevation source is a 32bit raster. Needs to be investigated further by Esri. Cheers Gordon

Andrew, This is an unusual error. The first thing that comes to mind here is the dense factor in the initial processing. I would possibly increase the point density. There may be other factors such asimage overlap, amount of image being processed, surface variablity and the ability to detect tie points. Without some samples and an idea of the flight pattern, it is fairly difficult to diagnose this. Gordon

Hello Mervyn, One of the keys when working in uniform terrain like this is to increase the point density and Point Cloud Densification. I generally Use, Ppint Density: High Point Cloud densification: 9x9 Pixels Also, you get better results in these types of environments by increasing the overlap when flying. Min is 80% forward 70% sideways Cheers Gordon

Hello Julie, How many ground control points did you lay out prior to the flight. In order to obtain accurate elevation data you should have a min of 4 across the flight area but 5 to 7 is desirable. Drones GPS data can be +/- 5m in the XY and any where up to +/-50m in the Z depending on the drone being used. If no GCP is used then actual height may vary across the image

Hello Bryan, Looking at the error your source imagery is ECW. Is this correct? If so then the error is expected as you cannot add ECW images to a services based environment due to licensing restrictions from Hexagon. . You will need to convert them to tiff and then try again. Cheers Gordon

Hello Mark, Yes this can be achieved. I have utilised raster functions to do this. Usually the alpha channel is 0 & 255. So what you do is as follows: Use the raster function to Extract the Alphas channel from the image (Extract Bands) This will give you a single band image of 0 & 255 Then use the GP tool Raster to Polygon. This will give you a vector layer of the image boundary and the image content. You can then filter the vector layer by either of the values. Hopefully this is what you are after. You can even use this shape to replace the footprints in a Mosaic dataset Cheers Gordon

(June 2021) Many of our Australian clients have now commenced or are contemplating moving their data from the GDA94 datum to Australia's modern datum GDA2020. The challenge with this move has been, that there was not a direct transformation between GDA2020 and WGS84. Data had to be moved through GDA94 to publish to WGS84. This has now changed as of January 2021. ICSM have released a new set of transformations. These now enable direct transformations to WGS84 (WebGIS) from GDA2020 and ArcGIS is now adding support as follows: ArcGIS Pro – Version 2.8 – Released May 2021 ArcGIS Enterprise – Version 10.9.1 – Late Q4 2021 Note: ArcGIS Enterprise 10.9 does NOT have these transformations. Released May 2021 The updated transformations are as follows: EPSG NAME TYPE / DESCRIPTION 1150 GDA94 to WGS84 (1) Null Transformation to WGS84 ensemble. Approximation at +/- 3m using assumption that GDA94 is equivalent to low accuracy WGS84 (ensemble) 9688 – New GDA94 to WGS 84 (2) [Non-Null] 7 parameter transformation: Equivalent to 8048 plus (null) 8450 9689 – New GDA94 to WGS 84 (3) [Non-Null] NTv2 Conformal & Distortion: Equivalent to 8447 plus (null) 8450 8450 – New to ArcGIS GDA2020 to WGS 84 (2) Null Transformation to WGS84 ensemble. Approximation at +/- 3m using assumption that GDA2020 is equivalent to low accuracy WGS 84 (ensemble) 9690 – New WGS 84 to GDA2020 (3) [Non-Null] 7 parameter transformation: Equivalent to 8048 plus (null) 1150 9691 – New WGS 84 to GDA2020 (4) [Non-Null] NTv2 Conformal & Distortion: Equivalent to 8447 plus (null) 1150 To the end user this means that you can now move to GDA2020 and publish your data to Web GIS (WGS84) and also transform the occasional GDA94 dataset to Web GIS and have it align with your authoritative datasets. If you need to know more jump over to to our Esri Australia Blog site where this is detailed further.

NOTE: in January 2021 ICSM released new transformations that support GDA2020 to WGS84 and Esri released ArcGIS Pro 2.8 in May 2021 which supports these. Please refer the following article for these updates New GDA2020 transformations for WebGIS

Thank you zkovacs, I actually found a good article by @IsmaelChivite after posting this question Custom JavaScript functions in Survey123 (esri.com) This describes what I need to do and also there is sample in the Survey123 connect which helps Cheers Gordon

I have a question about calling external URLS from ArcGIS Survey123 that I other have tried. I have been looking at the help files and community forums but cannot find any examples. What I want to do is from within a Survey: Populate a early questions in the first part of the form Capture these answers and concatenate them into a URL string. This URLS string is an external API from another system Call this formed URL to the API Populate additional fields in the Survey123 form based on the return from the URL call I believe this type of request is possible from ArcGIS Survey123 but I cannot find examples. If anyone has done this sort of reach out to another system I would be interested.

Will, In the first half of 2021 Esri will be releasing Fleet Management v2. This will capture information about the Drone, Battery and & Pilot from the moment the blades spin to the mission end. You will be able to perform all the mission analysis and drone history required by the regulatory bodies. It is a significant step up from where Site Scan is right now. Cheers Gordon

Esri have identified this as a problem and will supply a fix shortly

Interesting... I am seeing the same issue ArcGIS Pro 2.7 In the Messages just hangs with "Calling Folder" I see in the log file there is an error on the GDAL references C:\\Program Files\\ArcGIS\\Pro\\bin\\gdalplugins ERROR 1: Can't load requested DLL: C:\\Program Files\\ArcGIS\\Pro\\bin\\gdalplugins\\gdal_JP2KAK.dll\r\n127: The specified procedure could not be found.\r\r\n\r\n Which is repeated for every entry in this folder.
