Dear Cici Thank you for the feedback. I notice now that I had confused the issue a bit with mention of SLPKs when I was thinking of MSPK files. Sorry about that.  As I had previously received an error message when trying to add a Web Mercator tpk file to my Global Scene and then creating the MSPK, such as the below example. This error message made me believe that it was simply not possible to add a Web Mercator file to a Global Scene.  However I did manage to eventually successfully create a MSPK with my satellite image as a TPK in Web Mercator.  This MSPK now loads in Earth Desktop however the Earth Mobile app crashes as soon as I add the MSPK file. I think the fault may lie with the elevation surface used in the MSPK.  Although I have used a tif file as my elevation surface, with a known projection (and I have tried a few different projections), when I add the MSPK to Earth Desktop, I get an error that the file used as my elevation surface does not have a projection, when it does. See below error message. So in Earth Desktop, the scene loads but is flat with no elevation (when disconnected).  I can successfully load the MSPK in ArcGIS Pro and then I get no error messages and the MSPK layers are properly draped over the elevation surface. Perhaps this is an issue with ArcGIS Runtime and raster elevation sources?   I will need to explore different formats for the elevation surface, unless you can offer some advice? I suspect I need an elevation tile cache.  Thank you so much for your help.  Best wishes Mervyn ... View more

Dear CiCi Thank you for the feedback and willingness to further explore the reasons this is not working. I have just created a tpk file using ArcMap10.7  and the wgs84_512_tiling_scheme.xml tiling scheme. I then used that tpk to create a slpk  using ArcGIS Pro 2.6 beta 3, and the error still persists. I have added these files to a shared folder on Google Drive.  https://drive.google.com/open?id=173x5mx6-AuV0TdIYe72XY-FB43HxhAbX  Regards Mervyn ... View more

As I so wish that Site Scan for ArcGIS was available for Android devices, I have just added the request to develop an Android version to ArcGIS Ideas. So please do vote it up if it is something you too would like https://community.esri.com/ideas/18765  ... View more

Dear CiCi Thank you, this was exactly what I was looking for although surprisingly it has not resolved my problem. I have tested different tiling schemes and on two different computers but I always get the below error message when adding the SLPK to ArcGIS Earth.   I usually create my TPKs in ArcMap as Pro still has some issues creating TPK files. I create them using the Create Map Tile Package tool. Here I have tried various tiling schemes including wgs84_512_tiling_scheme.xml. I have also created them in Pro Beta 3. I then add the TPK files to a global scene in ArcGIS Pro 2.6 Beta 3 and create the SLPK using the Create Mobile Scene Package tool.   When I try and add the SLPK to ArcGIS Earth, I get the error message about the tilling scheme cant be adjusted to align properly with the current Earth spatial reference.   Am I dong anything wrong? I cant figure it out. There is a possibility that this may be a bug in Beta 3 software but I have my doubts.   I would love to get this to work. Mervyn ... View more

Hi CiCi I realise that tpk/tpkx files can be added as stand alone files to either desktop or mobile versions, but I would like to add a Scene Layer Package that contains a tpk/tpkx of my satellite image. The problem is in creating the SLPK file.  If I am correct, to add it to ArcGIS Earth, you can only do so from a global view and therefor the tpk/tpkx must be in WGS 84. The Create Mobile Scene Package tool cant run in a global view if the tpk/tpkx is in Web Mercator. That is why I need to create a tpk/tpkx file that in unprojected so that I can use it in the Create Mobile Scene Package tool. To do so, I need the appropriate tiling scheme. I hope that helps explain the problem. Mervyn ... View more

Could you please explain, perhaps with an example, what you mean by merging the different information of the common area polygons? Do you want to merge the information obtained in the attribute table?  ... View more

Hmm, that is not such a large dataset for join operations. I have worked with much larger datasets than that using a similar approach. It should not crash. Can you try a subsample or working with less data to test the workflow?  Looking at your modelbuilder screenshot, do you need to run the Select tool before the join operation? Have you tried running the Join Field tool without that? If you need to select a subset of data before the join then perhaps run the selection before running the Zonal Stats as Table tool. So the output of the selection should feed into the Zonal Statistics as Table tool and the Join Field tool. I noticed that your polygon file fits your raster exactly (so no variation in the values  - min, max, etc. are all the same - although not sure what a count field is doing in there..). If so, perhaps another workflow for you to consider would be to extract the centroid for each polygon and then use the  Extract Values to Points GP tool to get the raster value for each point (centroid) and then continue to work with the point files.  ...

When you run the Zonal Statistics as Table tool, you need to add your polygon file (Cell_30x30) as the "Input raster or feature zone data" layer. Then you need to specify a "zone field", a unique identifier for the areas you want to summarise the raster data for. In your case it will have to be the OID field.  Then add your raster and run the tool. Then open the output table and you should have a summary statistics for each of your OID polygons. Then join back using Add Join or Join Field GP tools, using the OID field.  ... View more

Hi Jamal I would use the Zonal Statistics as Table GP tool Zonal Statistics as Table—Help | Documentation and then join the results back to the input feature layer. Mervyn ... View more

A little bit of code from Arcade will do the trick. From the Labelling tab and Label Class group in ArcGIS Pro, click on the Expressions function.  This will open the Labelling pane with the Label expression subtab.  Just modify the code in the Expression box by adding Round at the start and put the $feature in brackets and then stipulate how many significant digits, like this  Round($feature.Size_ha,2) ...

Hi Amnoy Thank you for your suggestions. I have worked through them and respond to each below. "1. Start Pro and go to the Licensing tab. You will notice the option to take the licenses offline is checked. The Licensing Portal should state, https://www.arcgis.com. Make a note of the Workstation Alias." I did this and it confirms my Workstation alias as my Asus latop. "2. Open you web browser and go to arcgis.com. Log in with your AGOL account. Go to the Licensing tab>License Activity. Expand the account you took the license offline. Verify it is the same workstation alias you noticed in step 1. It's confirmation, this is the account you used to take the licenses offline on that machine." First time I have used the License Activity tab, good to know about it, and it confirms that my Asus laptop last used this license on 6 April and it has a red mark indicating it is disconnected. Unfortunately this is not the user name that Pro shows when looking at the Licensing tab in ArcGIS Pro below the "Authorize ArcGIS Pro to work offline" text. "3. Go back to the machine with Pro installed. Go to the Portals tab. You should see a list of Portal which should include https://www.arcgis.com. Verify it has the green check mark on it, indicating its the active portal. Verified its signed in with the account you verified in step 2. Then try to return the offline license." I can confirm that the Portal has a green check mark. "If this does not work, there may be unforeseen circumstances we're not aware of. There's just too many variables. I would start off with a Fiddler log. Perhaps it can provide information to the point of failure. Technical Support can help with this if necessary." I have logged this error with Esri tech support (Esri Case #02567155) and supplied them with my License.log file and specific details. I can share them with you too if needed? ... View more

Thank you for your feedback Tim. I had tried that.   ... View more
