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.

If it was for a single table, then I would have guessed it is because you have disabled editing for that layer. Check whether it is editable (List by Editing from Contents pane). But if this problem occurs across projects, then best to reach out to tech support.

HI Hellen There may be two reasons. Either (A) the display option for the layer is unchecked under your Legend items (see below image), or (B) you need to add the layer to the basket of layers that is currently being included in your legend. For B), from your Contents pane, you need to click and drag the layer into the actual legend that is included in the map layout (so that will be the legend that is shown in the exported map). It will then be included in the "basket" and it should display under the Legend items (A)

In the latest release of ArcGis Pro you can apply Blending which should maintain the details of the underlying labels

Hi there I would like to include the output of a raster function into the Tabulate Area GP tool, but my raster function output does not have an attribute table. If it were a traditional raster, then I would have run the Build Raster Attribute Table gp tool to create one. Is there a raster function equivalent or is there a different approach to follow? I need to work with categorical data. Thanks.

Hi Juliet For instances where I frequently update my coordinates in a table, I make use of Event Layers (https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/make-xy-event-layer.htm). Add your Excel or CSV table to Pro, run the Make XY Event Layer gp tool, then whenever you open up Pro, it will display all the coordinates of the data in the Excel table. You can edit the data in Excel while the table is open in Pro, but it will only update once Pro project reopens.

I did some homework and found the Lookup GP tool easily creates new rasters based on any of the fields in the attribute table. Would still be great if the Zonal Statistics and Table tool could let the user specify the input field sometime in the future :-).

Hi there I have a 16 bit raster which has an attribute table with several numerical fields (density of several invasive species). I would like to to run the Zonal Statistics as Table GP tool to extract the average density of various invasive species for each of our reserves. Unfortunately, when running this tool, a user cannot specify which attribute field to use in this GP tool. The tool uses the default value field. I am guessing there is no simple workaround? The Tabulate Areas GP tool only considers categorical classes, so it is not an option (and not the ideal output). I suspect the way forward would be to create individual rasters from each of the attribute field names. And then use these in the Zonal Stats as Table tool. This sounds simple but i can't find a tool to do so. Any advice? Thank you.

I am not sure if this helps but I have been testing the Beta version of ArcGIS Pro 2.9 and the problem is fixed. I believe Ersi will release 2.9 before the end of november (probably closer to the middle of November). As a workaround, you could try the Tabulate Intersection GP tool. Unfortunately it does require an advanced licence. Do see https://pro.arcgis.com/en/pro-app/latest/tool-reference/analysis/tabulate-intersection.htm
