I'm using ArcPy to iterate through maps in a Pro project. I have only one map in the Project called "Mines". However, when I use listMaps to iterate through the maps in the aprx, it returns two values called "Mines". Any ideas why this is? Furthermore, if I list all the layers in each "Mines" map, the layers are slightly different. The first Mines map in the list contains layers that I actually deleted from the Pro Project, but the second one doesn't have this problem. And yes, I saved the Pro Project.  Here's the code:   aprx = arcpy.mp.ArcGISProject(path_to_project) for mp in aprx.listMaps("Mines"): print(mp.name) Really strange. Someone tell me I'm not in the Twilight Zone.     ... View more

I have an ArcGIS Pro Project containing layers that have shapefiles as sources. I wrote a script using ArcPy to convert this data to File Geodatabases. Everything works fine here without any issues.  The next step I want to take is replace the data sources of the same layers that I exported, so that they will be referencing the new file location in the File GDB. The best (and only?) way to replace the data source and dataset name is to use Layer.replaceDataSource . But when I use this Layer method, I get this error:    AttributeError: 'Layer' object has no attribute 'replaceDataSource'   This is because replaceDataSource is a method found only in arcpy.mapping's Layer class. In other words, I'd need to use an ArcMap map document to utilize this method, instead of Pro. Is there a way to do this using arcpy.mp library? Are there any other ways to achieve what I'm trying to do in ArcGIS Pro with ArcPy? Thank you for the help! ... View more

I have an app in AppStudio that contains a map with several feature layers. The user for the application will be interacting with the layers and submitting data from app to elsewhere. I want the user to be able to click on the map (it will never be exact, therefore reasonably close) near a line feature and retrieve the coordinates for the nearest point on the line. For example, user clicks on or near the polyline feature. This creates a Graphic that is snapped to the nearest point on the polyline feature. This allows the app to retrieve coordinates where the user tapped on the feature. This is the workflow I would like to implement: 1) User clicks on or near polyline feature 2) Get the coordinates for the point that user tapped on and calculate distance x to polyline feature (using Geometry Engine's distance method).  3) Plot point on line that is x distance away from tapped point to line feature. 4) Place a Graphic on this final point on the line feature to indicate that the snapping has completed. How can I achieve step 3? I have a distance that I can calculate successfully. Is the best way to do this by calculating a buffer with x radius and then finding points of intersection with the line feature? Or is there a better way? All I want to do is just snap this point that is not on the line to the line.   Thanks for the help! ... View more

I'm working on an AppStudio app that works offline. The app's webmap is created from an MMPK and contains a point layer that the user can interact with. Here's what I want to do:  I want to click on the map (outside the layer and its features) and find the geographically nearest point feature in the layer to the point that I clicked.  This seems like a pretty reasonable thing to want to do, but the GeometryEngine doesn't perform well in this scenario due to the large number of point features in this layer. Here's what I've tried or thought about trying, but doesn't work. 1.  Create a buffer polygon for a fixed distance around the point that I click. Find all features in the feature layer that intersects with buffer polygon. Find distances between original point and each of the intersected features. Sort these distances to find the feature that is closest to the point that I clicked on.  This doesn't work because my feature layer has 120,000 point features. If I iterate through each of them to check if they intersect with my buffer polygon, it can take a LONG time.  2. I've thought about using ClosestFacilityTask, but this requires an online connection. So not an option for me.  Ideally, I guess I would've liked a Runtime method I can call where I input in these parameters: 1) original point's geometry and 2) feature layer. This would return a single feature that is closest to my point. But this is not a Runtime feature AFAIK. Does anyone else have any ideas on how to proceed here? Any help appreciated.  ... View more
