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.

Hello Kylie, Creating your own basemap in GDA2020 (Projected or geographical) will mean that you need to 1) Define your own tiling scheme for that basemap. Yes this is different to the global basemaps as they are all in WGS84 Web Mercator Auxiliary Sphere. The traditional tiling scheme for the global basemaps is defined if you choose the ArcGIS Online tiling scheme. (Generate Tile Cache Tiling Scheme) 2) Use this tiling scheme as the definition for your basemaps. (Manage Tile Cache). NOTE: I would consider using Vector Tile Packages as they are more efficient and faster to create and update. 3) Package the tile cache for loading to ArcGIS Online or ArcGIS Enterprise by using the Export Tile cache tool 4) Once you have this basemap package then you publish to ArcGIS Online or ArcGIS Enterprise using the Share tools 5) You can use this as you basemap but everything you place on-top of it now will be projected to GDA2020. You cannot add other global basemaps behind as they are in WGS84 Web Mercator Auxiliary Sphere but the map will be in GDA2020. 6) From this you should be able to add the WMS capability (Which includes the WMTS for cached basemaps). Also good suggestion on the GeoNet for creating a GDA2020 discussion group I will look into this Cheers Gordon

Hello Nic, In the Mosaic dataset on the defaults tab there is a setting "Maximum number of Rasters Per Mosaic" by default this is set to 20. Recommend increasing this to 200. You should then see all of your rasters Gordon

I have a calculated field in my survey123 form. The various inputs from other questions derive the total value in this field. I want to be able to colour the field in the form if it below, between or above values. For example Calculated Below 5 = green Calculated between 5 & 9 = orange Calculated above 10 = red How can this be achieved in the survey form?

Hello Jose, I have numerous clients who are also asking this. As of today Drone2Map produces output from single missions. My current methodology is to take the outputs from Drone2Map and put them into a Mosaic Dataset in ArcGIS Pro. Then from the Mosaic dataset produce a Tile Package that I can load to ArcGIS Online or ArcGIS Enterprise. Cheers Gordon

I have a feature Service on ArcGIS Online which his subtyped. When I select a different Subtype the domains for attributes update to reflect the type of subtype. I want to create a Survey123 project from this Feature Service. When I create the Survey123 project it does not list the subtypes and does not list the domains associated with each subtype. The way around this I see is that I need to modify my feature service so that the Subtype becomes a domain. Then I produce filters based on the domain which only show the fields associated with the domain. This though creates extra fields that I would otherwise not need if I could use subtypes? Cheers Gordon

Hello Brandon, You are correct. I have a primary feature class of the feature being surveyed and the Surevy123 feature class. From what I understand there is no facility yet via this methodology to have a standalone table. Cheers Gordon

‎12-08-2016

Brandon, The workflow I used is as follows: Create a new Survey123 project in Survey123connect and load to ArcGIS Online Download the feature service to a file geodatabase In the file geodatabase create your primary feature. Ensure it has a common ID with the survey123 feature class. Create a geodatabase relationship between the primary feature class and the survey123 feature class using the common ID In a Map document add both layers with the Survey123 feature as the first item in the table of contents Publish as a new feature service in ArcGIS Online (The survery123 feature class should be ~/FeatureServer/0) In the Survey123connect app, open the spreadsheet and switch to the settings tab Update the submission_url parameter to match the feature service for the ArcGIS Online Feature Service In the Survey123 project folder delete the .iteminfo file In ArcGIS Online delete the original associated survey123 folder Republish the Survey123 project and it should associate with the specified feature service. Hope this helps Gordon
