Hi, As explained in ESRI documentation, only 'single symbol' or 'unclassed colors' symbologies are available for binnig enabled layer. If you wish to apply 'graduated colors', you can use 'Vary symbology by attribute' subtab and write a custom Arcade expression to derive the graduated colors based on an attribute. https://pro.arcgis.com/en/pro-app/latest/help/mapping/layer-properties/symbolize-binned-feature-layers.htm For example, I wrote a simple if else Arcade statement to calculate "rgb(r, g, b)" text value used to draw the Solid Fill layer in the symbol. Here, if a total if greater or equal to 50, an "rgb(255,0,0)" red is output, else it is "rgb(255,255,0)" yellow, as shown in the square binning below. It works but I have to admit it is not easy concepts to use. Recently, I had a similar issue recently and you can look at this post for exact instructions to use: ArcGIS Pro 3.0.2 - How to apply colormap file .clr to feature class symbology? Hope this help.     ... View more

Thanks. It helped and it is informative. As expected, the ArcGIS Editor for OpenStreetMap in ArcGIS Desktop (ArcMap) could not open ESRI flavored .pbf. In addition, ArcGIS Editor for OpenStreetMap is not available in ArcGIS Pro either. ArcGIS Enterprise can export its own .pdf flavor but it is cumbersome to use... I will not use .pbf again for the time being. ... View more

Thanks. It eventually worked. The workflow is rather cumbersome and in addition to the resources mentioned above, follow the Attribute-driven instructions closely: https://pro.arcgis.com/en/pro-app/latest/help/mapping/layer-properties/attribute-driven-symbology.htm     ... View more

Thanks. Appreciated. I did went through the Arcade Developers documentation and found the syntax confusing or cumbersome. When you call the function, you do not send any variable but in the function declaration there is an (x) variable... This x variable is like a 'dummy' variable but if not in the syntax, it produces an error... ... View more

Thanks Luke. I already tried the arcpy.AddMessage() but this one does not work in Code Block... ... View more

Hi, I managed to compute a checksum on attribute with Calculate Field code-block, using the hashlib module   import hashlib def hash(attribute): hash = hashlib.md5(attribute.encode()).hexdigest() return attribute   Here I used MD5 algorithm. But SHA256 is just as good (or better). Just as simple as that! Ideally, I would like to compute this MD5 checksum in Arcade in attribute rule...   ... View more

Correct, I have seen the GenerateCheckSum from the Aviation Charting extension... However, this needs extra licensing and I am unsure if it exists in ArcGIS Pro. Also, attribute rule cannot use Python script. However, if I were going with Python, I found: # Python program to find SHA256 hash string of a file import hashlib filename = input("Enter the input file name: ") sha256_hash = hashlib.sha256() with open(filename,"rb") as f: # Read and update hash string value in blocks of 4K for byte_block in iter(lambda: f.read(4096),b""): sha256_hash.update(byte_block) print(sha256_hash.hexdigest()) in https://www.codegrepper.com/code-examples/python/frameworks/file-path-in-python/python+sha256+checksum+file I wonder if it is doable to loop through selected attributes (including geometry), instead of byte_block, to calculate a SHA256 checksum...although computing on alphanumeric character instead of bytes would make the algorithm not as robust! ...

Thanks Rob. It is a similar approach I wish to apply into a GDB. Calculate a checksum (any algorithm: MD5, SHA-256...) for each single features. Ideally, I would implement it in an attribute rule. Is there any geoprocessing tool to calculate a checksum? Or any Arcade code to calculate a checksum in an attribute rule? ... View more
