I don't tend to process data drawn down from a feature service but may be you could explore the Python API as an alternative way of grabbing that online data? Have a look here. ... View more

You would use arcpy to manipulate the contents of a map, search help for code examples on addDataFromPath(). ... View more

Sounds like you have not got the sequence right, here is a video to show you how to create a polygon with a hole which you can then use to shade/mask data outside the polygon of interest. Click on it to enlarge.   ... View more

The short answer is no. You say nothing about what your data inputs are, any environment settings set, what version of software, where you data is stored... Suggest you edit your question and add significantly more detail. ... View more

Outside goes to where...infinity. How do you map the edge infinity? You can't! Create a new polygon layer , create a rectangle that encompasses everywhere you are going to map. Then use the editor clip tool to clip out your polygon, the resulting polygon you can shade. Never clipped out a hole from a polygon then read the help file here. ... View more

I realised I have come "late to the party" but I thought it's worth advertising that RivEX for ArcPro has a tool for tagging assets/bank features with which side of the river they are. More information about the tool can be found in the online manual here. ... View more

Yes it would be very easy, you use the Describe object on a dataset. ... View more

Fine tuned to perfection, nice! 🙂 ... View more

OK now you have described you data better and what you have tried, I need to ask do you have the following scenario:  You select your yellow polygons by a date and those selected polygons can exist in more than one blue polygon, so when you produce your map you might be showing 2 or more blue polygons? OR  You select your yellow polygons by a date and that selection only exists within a single blue polygon, so this case your map only ever shows 1 blue polygon, like you show in your original question? I ask this as the index layer in a map series requires a SINGLE feature to step over but if your units are selecting by date across multiple blue polygons you can't do what you want using the GUI in ArcPro, you are going to have to script this. I don't think modelbuilder is the solution either as it has little to no interaction with a layout, you would need to control the layout using arcpy. ... View more

I develop RivEX and thought you might be interested in how I protect my source code. I suspect I have a  "Heath Robinson" approach compared to others! I develop in an atbx, not a PYT. So I edit directly into my atbx toolbox. Sometimes I do quick edits from the interface provided when you right click on your script tool and go to properties. When I'm writing the bulk of the code I right click > edit and it all happens in VSCode. So I save my edits and shut down VSCode and it magically appears inside the atbx. I have a subfolder with some python modules, these hold generic functions and are unprotected. But in themselves they are a small cog in a big machine, so knowing anything about these functions does not really expose the interesting code stored in the atbx. When looking at the properties of a script there is button to encrypt the code in the execution section. I use this to protect the source code. Any code in the validation section is completely unprotected, seems like a design flaw to me. I have simple xml file that encrypts a unique number extracted from the OS and all tools have a function that decrypts this. The xml is built by me after someone purchase a license. I zip all this up and its available on the website but limits itself if there is no valid xml file. Limitations of my approach: Requires user to install into the root directory and nowhere else as the xml lookup is hardwired. There is no automated way of calling the encrypt button, so I have to manually do it. As I'm the sole developer it's just a pain in the a$$ and something I live with! Have 50 tools, then you need to provide 50 passwords and press that encrypt button 50 times. Not at all ideal. I push as much of my generic code out into the subfolder, this code is free to see. Validation code is unprotected, so any decrypting of license files which would seem sensible to do in the validation section needs to actually be done in the execution section, this means every tool is duplicating these functions. Not ideal. Positives: Single zip file to distribute and thus easy to install Maintaining code is easy it's the encryption step that is laborious. Can take advantage of new functionality in toolbox as ESRI releases it. Hope that helps? ... View more

Sorry I find your description contradictory, you say ...take that list of numbers and display the WHOLE blue layer..., you then say you have tried a variety of selections but not happy with the results as it is picking up other blue polygons. But you just said you wanted the whole layer? ... View more

Sounds like you want to be exploring the ArcPro SDK rather than arcpy if you want to capture onclick map events. ... View more

If you want to do this in model builder do this: Extract all vertices Extract start vertices Extract end vertices Use start vertices to select intersecting all vertices Use end vertices to add to selection intersecting all vertices Delete selection from all vertices. This can very easily be done in modelbuilder. ... View more
