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

Hi Will So I certainly tried signing into Pro with both the named user accounts to return the licenses but neither account work. It is easy to establish which account has the licences "booked out" by looking at the extensions and expiry date. I also confirmed that the license was taken offline by that particular account by going to AGOL and trying to return one of the extensions. AGOL then warns me that it is unable to make teh change because the license is taken offline.  I have contacted my local Tech support office but I am concerned this will just happen again. Cant think I am doing anything wrong. Mervyn ... View more

Hi Marco I was able to follow your instructions and import the point, line and polygon features into a geodatabase. Thank you. However I am unable to symbolise any of these three using any of the .lyr files that came with the ArcGIS Editor for OpenStreetMap extension. Do you know where i can download layer filesthat will work? Or better still, download any .lyrx files for the Open Street Map data? Thanks ... View more

Excellent, glad it worked. ... View more

Hi Mo I am not sure exactly what you mean by threat level but I suspect it may be something along the lines of, hypothetically: Critically Endangered (CR) = 20, Endangered (EN) = 10, Vulnerable (VU) = 5, Near Threatened = 1. If so, then I suggest you try: Running the Count Overlapping Features tool only on a group of similar threat layers, like only on the CR layers. Then do the same for each of the other threat categories.  Then add a new field to the attribute table for each outputs of the Count Overlapping Features and call this new field "score" and use Calculate Field to calculate the score for each output (Score = !Count_! * 20) (or whatever your threat weighted score is)). So at the end you will have several polygon datasets each with a "score" field that is a combination of the count of overlapping features multiplied by your threat weight. Next run a Union on these polygon features. If you dont have an advanced license you may need to run this tool several times until all your polygon layers are in one layer. An advanced license can take several files as input features at one time. Then add a new field to the output of the Union GP tool and call it "CombinedScore" Use Field Calculator to add up the respective "score" fields. (CombinedScore = !Score! + !Score_1! + !Score_2!) So in the end you should have a weighted threat score field which you can symbolise and prioritise.  Is this what you are looking for? Good luck and let me know if it worked or if you require a different process and I misunderstood your need.  I do think this process may be easier in raster.  Mervyn ... View more

Its your projection. I changed it to Web Mercator and the image then loads with the data. ... View more
