Thanks, I tried that but got a null value returned.

I'm working on a project to help our Stormwater division collect data for culverts and rain swails using a high-accuracy GPS. The data will be 3D polylines. They need to indicate the direction of flow, from the high end to the low end of the pipe. I'm still trying to figure out how I can visually represent that, but for now I'm starting with the attribute data. I need to calculate the difference in elevation from the start point to the end point of the line. I found a tool called Calculate Geometry Attributes that can calculate these values, which works great, but I'd like to automate the process using an Attribute Rule in the database. Does anyone know how to calculate the Z value of a point using ArcGIS Arcade?

Actually the road segments in the middle weren't a problem because they only intersect each of the other road segments in one place, so they split normally. It was just the one that split the other in two places that was the issue.

Yeah, that's what I settled on last week. I stopped my line short of the second intersection, added a new line segment, and then merged it in. Thanks.

Have you ever had a situation where you need a new road segment to split an existing road segment in two places? This has been driving me nuts for a couple of weeks now. I could swear I was able to do it before, but it's not working now. I've got a new road segment that intersects an existing road segment in two places. When I draw it in, it splits at the first intersection, but it won't split the second. Looking at the attribute rule, it has the following code: // If the road was created from a split its id will have a prefix of '::' // Don't process any futher splits to prevent getting in an infinite loop var id = $feature.centerlineid; if (Left(id, 2) == "::") return id; I guess that means it'll only do one split. I just think it's a little weird because it's not uncommon for a road to intersect another in multiple places. It's not a big problem, I can just split it myself and adjust the address ranges, but I was hoping this solution would have automated that.

I've got the same kind of question. I'm working on a demographic analysis by census block group. There's about 150 of them in my county, and I'd like to have links to the demographic in the pop-up for each block group, but I can't find a way to do that in BA. I tried making a Story Map, which created the infographics automatically. But it also made a map for each block group and put them all into one very long story map.

I set up a tropical weather monitoring dashboard based on this blog article from Esri: Updated Arcade Code for Scaling Symbology When setting the map symbols using images stored online, the symbols would often stop displaying either over time, or depending on the computer or browser displaying the map. On all PCs/browsers tested, I was logged into my organization with my account (the account that created the items). I tried sharing the map, layers, and dashboard with Everyone. I also tried uploading the symbols to my organization, and sharing them with Everyone. To troubleshoot, I also tried disabling any browser extensions and lowering my security settings. Below is a screenshot I took showing the blank symbols. I've tried several times to set the symbols, but they keep disappearing.

Thanks. I looked into it and resolved the issue by adding the following lines to my expressions (with different variables in each respectively): if (Building == null) return null

I wrote an Arcade expression to calculate the zip code of an address point from its intersecting zip code polygon, and it works just fine: var fsZip = FeatureSetByName($datastore, "ZipCodes", ["Zip_Code"])
var fsZipIntersect = Intersects(fsZip, $feature)
var zip = First(fsZipIntersect)
return zip.Zip_Code I use a similar expression to calculate the municipality from the zip codes feature class with no problems: var fsZip = FeatureSetByName($datastore, "ZipCodes", ["PO_NAME"])
var fsZipIntersect = Intersects(fsZip, $feature)
var city = First(fsZipIntersect)
return city.PO_NAME But when I try to do essentially the same process to calculate the intersecting neighborhood or building footprint I get an error, "Dictionary Type Expected". var fsBuilding = FeatureSetByName($datastore, "BuildingFootprint", ["bldngid"]
var fsBuildingIntersect = Intersects(fsBuilding, $feature)
var Building = First(fsBuildingIntersect)
return Building.bldngid var fsNeighborhood = FeatureSetByName($datastore, "Neighborhood", ["nbrhdid"])
var fsNeighborhoodIntersect = Intersects(fsNeighborhood, $feature)
var Neighborhood = First(fsNeighborhoodIntersect)
return Neighborhood.nbrhdid All of my feature classes are in the same file geodatabase that I'm using for testing, so they're all in the same data store. Does anyone know why this might be happening?

I tried updating my map to have the Master Road Names table connect to the database using the account that owns the RoadNameIndex domain, but now I'm getting schema locks when trying to update the domain.

Using the new Address Data Management solution, the process for adding streets involves running a python script that imports the Full Road Names from the Master Road Name table into the RoadNameIndex domain. In an enterprise geodatabase, it seems that only the owner of the domain can update it. We've got a multi-user editing environment where multiple users will need to update the domain when adding streets. Is there a way that each of our editors can update the RoadNameIndex domain using their own accounts?

Thanks for responding. I tried this but I get an error on line 10. It looks like it can't concatenate a string and an integer.

We're looking to quality test our address data, and I was wondering if anyone knows if there's an updated Fishbone tool for ArcGIS Pro. Thanks.
