Sun, Rasters only store ONE field attribute directly and it is contained in the “Value” field. Any other fields may have been added by users or copied during a polygon-to-raster conversion process. Most raster tools use the Value field by default, and not many of them allow you to select an alternate. If you have a soil raster, then I surmise that the Value field contains a unique number code for each soil unit, and the slope field you indicate was merely copied from a polygon soils data set when it was converted to the raster. Presumably this field already contains the average slope of the field, so if you trust this value, then you don’t need to run zonal stats at all. To use zonal stats, you need a slope raster containing slope values in the Value field (not a soils raster containing a soil code). If you have a digital elevation model already, you can calculate slope from the DEM quite easily with the Slope tool and use that in zonal stats. You might want to review the Help files on how rasters are stored and analyzed; it sounds like you have might some misunderstandings about how they function. Maribeth

If you want world boundaries, then exporting a raster is NOT the way to get them. You should be able to find a shapefile or feature class (with the borders as lines or polygons) in a variety of places, including ArcGIS Online, Esri Data and Maps, etc., the ArcGIS Pro tutorial data, etc.

You might also try the Zonal Statistics as Table tool, with your polygons as the zone data set and the crop raster as the values data set. It will provide a table with a Count field for all the pixels in each polygon. You would need to reclasify (Reclassify tool) the raster so that you would have only corn or only soybeans in each raster. Give each a value of 1 and a nodata everywhere else. The output is a table that you would join back to the polygons. You will need a unique identifer for each field; the ObjectID should work if you don't have anything else. You will need a Spatial Analyst extension license to run these tools. Maribeth

I submitted this to tech support and it was confirmed as two different bugs. These were attached to Esri Case #01849644 if you want to follow up further. For those needing to get work done, it works more reliably if you try to create the new domain from the Domains box in the Fields tab. After you create the new field and assign the data type, save the field update (optional but seems to help), then click in the domains box in the field row to create either the coded or ranged domain. The field type and domain type get copied into new domain.

I am systematically working my way through Pro for my book update and there are a few things I do like: Multiple maps and layouts. I wrote a paper last summer and had to create a different map doc for every figure, even though it was all the same data being used. I'd update some annotation in one figure and then have to do it again in another. I'd zoom into the map in data view to fix something and then have to re-scale it for the figure. I like that Pro creates a geodatabase for the project. With ArcMap, my students were forever saving things in the default geodatabase on the C drive and never finding them again. I used to create "junk" databases to hold intermediate stuff from Spatial Analyst workflows. Now I just let them save in the project geodatabase Love being able to enter an attribute in an edit template and then create features with that attribute value. Love that I can keep a tool open and edit it after it finishes, instead of having to reopen and fill the whole thing out again. Created 4 feature datasets in a geodatabase in under 20 seconds yesterday. Neat that the map display units can be set to UTM and automatically adjust for the zone you are in. Query builder panel is more intuitive for beginners, although more tedious to operate. Thank goodness for the SQL view. My dislike list is still pretty long, mind you, but I expect I will get used to most of them in time. Except the symbols. Is it just me or are the default styles ugly, with the ugliest and least useful symbols at the top, so you have to scroll down to find reasonable ones every time? It was heaven to find you can import the old ArcMap styles. First thing I do with every new project.

I checked the references, but they all say how to move vertices--just click and drag--but not nodes. I'm starting to think that the functionality to move shared nodes simply doesn't exist in Pro. You can sort of get the right behavior if you select the street edge with the Move tool and move/ rotate it until the node is centered in the intersection, but this only works for perfectly straight streets, and it may make the node on the other end worse. In other situations I guess you just have to re-digitize the feature with Replace Geometry, or edit and snap vertices individually for the features sharing the node. Another sad face for Pro.

I am creating some domains in a geodatabase. I can create Text coded domains and Long coded domains just fine. If I try to choose a Short field type (on a new domain!) it keeps defaulting back to Text, even if the Field type is the first thing I try to set in the new domain. If I choose Float, it defaults to a coded domain (which is impossible and won't work), it will not let me change it from a Coded Domain to a Range Domain. See video attachment for a demo. I tried closing Pro and reopening the same project. I tried closing and restarting with a different project. The behavior persists. I tried getting to the Domains window from a different feature class that actually had a Short field in it (the first one did not), but it did not make a difference. Help! I'm sick of Pro right now. And don't even ask my about my earlier experiences today trying to edit a planar topology...

I am trying to edit road centerlines using a map topology. In ArcMap you created a map topology, used the topology edit tool to select a node, and when you moved the node, the attached lines came with it and stayed attached. In Pro, the map topology is on by default and the Modify Features tools have an Edges pane. I can select and edit edges but I cannot seem to select nodes. I've tried both Move and Edit Vertices tools. The Help claims that you can edit both edges and nodes, but they neglect to tell you how to actually select the nodes. If I edit the vertices of the edge, the other lines become unconnected after the end vertex is moved. In Edit Vertices, if I hover over the intersection I get a little purple circle like it's going to let me select the node, but it never does. In Move, I can select the node (I think), but then I am unable to click and drag it anywhere (see attached video). It just sits there.

Trace is different. Stream digitizing isn't that useful unless you have a digital pen and do a lot of curvy polygons like geology and soil units. Then it is a godsend. Guess I'll have to use ArcMap for it, at least for a while. Yes, I found that list of tools that aren't available, but lots of stuff wasn't a tool in AM. Good to have it, though. On the bright side, my book's Pro edition is gonna be a lot shorter than the AM edition!

Can you still do stream digitizing in Pro (e.g. it follows the mouse instead of you clicking each vertex)? I can't find it or any mention of it in the help. Does any one know if it has been ditched permanently or is just planned for a later release? Freehand is pretty clunky in comparison--you can't start/stop and you can't set the stream tolerance. I've been searching for a comprehensive list of ArcMap stuff that is not in Pro. Anybody know of one? The search engines t are spectacularly obtuse at times...they are convinced I am looking for info on linear water bodies...

I loved that ol' ArcMap right-click a layer with a selection and "Create Layer from Selected Features" and I used it all the time. There does not seem to be a true equivalent in Pro. Your options seem to be: 1) Export the data, which creates another feature class. Usually I just want a temporary layer, not another piece of garbage cluttering up my geodatabase. 2) Use Make Layer Feature, but this only works for attribute queries. You can't take a selection generated with interactive selection or Select by Location and save it as a new layer. (I tried running MFL on a layer with a selection, without specifying a query, and it ignored the selection and output the whole layer again, e.g. it did NOT honor the selected set). 3) Use a definition query (also only works for attribute queries). Anybody found an alternative to export? The ArcMap option was SO elegant!

Have you tried using a reference scale? If you set the label sizes appropriately for one map, they will then be scaled proportionally when you view the other map. Just set up your labels for one map, then right-click the map and choose Set Reference Scale. Map reference scales—Properties of maps | ArcGIS for Desktop

I've been playing with this for several hours. You workaround of exporting the table (so the fields are there but it is no longer a joined table) does work. However, the scary thing is that the attempt to do SbA or MFL on a joined table appears to corrupt the data and make it unjoinable in the future, even after removing/re-adding the data to a new project (the joined fields are null). That is why the second attempt fails; the join is no longer valid. I had to replace the data from another source to get the join to work again. After another run through SbA or MFL on the new data (it works once), the join went bad again. This is a nasty one. I put in a tech support request on it.

Oh, and I did also try saving as a .xlsx file (office 2013). That didn't work either.
