Currently, when deploying a Conservation Solution such as Wildlife Management, there is no option to change the name of the solution when it is being deployed. And you can therefore only deploy one solution per user in an organisation. I support several protected areas and I would like to deploy several reserve specific solutions as the biodiversity/threats differ significantly between the reserves. Therefor please can you add the ability for me to provide a prefix before deploying the solution? A few months ago an ArcGIS Pro script could be used to rename the deployments from ArcGIS Pro, but that is no longer possible as the solution is now 100% deployed within ArcGIS Online. This request may apply to several other solutions.

Sentinel 2 Views is a fantastic product (for which I am very grateful) but it can only be used for visualization, even though it is supposed to be "analysis ready". In order to actually use it for analysis, currently one cant access more than 4000 rows and columns at a time. That is 4x4 km which is frightfully small. Please can this limit be dramatically increased so that we can use it for more than just visualization?

Currently, when adding in data which is in a different datum to that of the map properties, ArcGIS Pro assigns a datum transformation based on the maximum spatial extent of ALL the layers and basemap listed under the Contents pane. If you have a Esri basemap then this spatial extent will be a global extent, which is seldom the scale at which I work (and I suspect the scale at which most of us work). My idea is to either (1) drop the basemap from any transformation calculations, or (2) under Project>Options, provide the user with the option to exclude the basemap from any datum transformation calculations.

Sorry for post, I see now that one does not need to reference the feature classes within a Feature Dataset any differently. They are treated as any other Feature Class within the geodatabase from what I can see. I did not anticipate that. Wonderful!

I have successfully set up a Calculation intersect Attribute Rule using two Feature Classes, but how do I do so using Feature Classes within a Feature Dataset? How does one reference them? I have defined it below: var fsInput_BU = FeatureSetByName($datastore, 'Burn_units', ["UNIT"]) How would I do so if my BurnUnits feature was in a Feature dataset? And can one also easily define variables across both one these (e.g. one var in a Feature Class and the other in a Feature Dataset?) Thanks so much. I am new to Arcade and Attribute Rules.

If you still have access to the original raster's, try Band Collection Statistics https://pro.arcgis.com/en/pro-app/latest/tool-reference/spatial-analyst/band-collection-statistics.htm I am not sure of vector-based methods. You could possibly convert your polygon data back to raster format using Polygon to Raster GP tool.

I expect that the World Imagery firefly basemap would be the same as the World Imagery basemap when zoomed in. Do some spot checks to confirm. You can then check the date of the world imagery basemap by adding World Imagery tile layer from the Living Atlas. You can then get the date via pop-ups.

You should be able to create a MMPK with just a Pro license assigned to you. A Publisher extension is useful in that you can then share your MMPK with users who dont have an AGOL username and password, but it is not required to package maps. I have 2 suggestions. (1) Check that the files in your project are free from geometery errors. Run the Repair Geometery tool on each of them to ensure they are OK. The map projection should also be the same as that of your raster and basemap (.tpkx, .vtpk, etc.), if included. This should not cause the packaging to fail but it wont display correctly once oppened. (2) Try creating a MMPK in a new projet using some simple data to check that you can successfully package a MMPK. If successful, then gradually build the project up from there. Good luck. Mervyn

When you load a raster (or a shapefile) into your map, it is listed as a layer under the contents pane. Any changes you make here (like changing symbology, visibility, labelling) are properties of the layer and not the underlying raster or shapefile. Even exporting it, does not change properties of the layer. So you need to save the properties of the layer (symbology, pop-ups, visisibility, definition queries, etc) as a layer file. Layer files are really awesome and I use them a lot. Just right click on the raster under Contents pane, then go to Sharing>Save As Layer File. This will save a file with a .lyrx extension. Then the next time you want to load the raster, load this layer file and you will have your original symbology, pop-ups, etc.

Hi Vicky I do a lot of these kinds of analyses. Once again you are using the right set of tools. Just make sure you use the correct input field when running Zonal Statistics as a Table. Click on validate and it will warn you if any buildings have no data in corresponding solar radiation table. You used the index field which is perfect. You also used the sum option which sounds right for adding up the watt hours per square meter. Then I would also run the Join Field tool tool using teh index field. But it is always good to validate your output by adding in the original radiation surface and then zooming into a small building and confirming that the output seems reasonable for that building (within range).

Hi Vicky Can you be more explicit about what you want to achieve? I would need a lot more information to understand your datasets and how you want to combine them, because straight off I dont think it is easily possible. Perhaps there may be some work-arounds.

I seem to recall struggling with this some time back. You have followed the correct process, but once you have built your attribute table, remove the raster from your project then add it in again. I don't think you need to restart Pro but consider that if your attribute table does not show.

You could use the Extract Bands raster function to extract the band of interest and then use this as input into raster calculator. Do see https://pro.arcgis.com/en/pro-app/2.8/help/analysis/raster-functions/extract-bands-function.htm

Do take note that the ArcGIS Field Maps app only runs on Android and iOS (Apple) devices. So it won't run on a Surface Pro.

You need to run the Zonal Statistics as Table tool, but will need the Spatial analyst extension.
