Hi, I'm using arcpy and ArcGIS Pro 3.1.3 I have a Lines feature class with 'millions' of line features and I need to use arcpy.management.UnsplitLine() on it. The trouble is, is that this outputs the unsplit lines to another (new) FeatureClass rather than replaces the unsplit lines. How can I locate and copy from the original FeatureClass to this new FeatureClass, all the lines that were NOT 'unsplit' I have a similar problem with dissolving polygons. Thanks in advance, Zoltan ... View more

Hi, I have over 2700 FileGDBs in which to count feature occurrences based on an attribute value. The attribute field (FeaType) has over 200 possible values. (Typically: Tree, Road, Building, etc etc.) I need to count the occurences of each feature type, per FileGDB and put them in a table with 1 row per FileGDB and 1 column per FeaType value. Putting them into a table is no issue - I am using xlsxwriter. What would be the most efficient way to count these features? I have tried iterating through each FileGDB, each FeatureClass, row by row incrementing a table entry based on the FeaType value - very slow 😞 I could try iterating through each FeaType value, then using that value to 'select' and 'getcount'. But surely there is a more efficient way? Some pointers would be great.   Thanks in advance, Zoltan ... View more

Hi, I'm looking for an efficient way to see which vertices in one feature touch a vertex in another feature. I will then need to edit the vertex of the "first" feature. Problem: I have a large polygon feature set that I will select some polygons from. For each polygon in this subset, I need to check if any of its vertices coincide with that of another (Polygon or polyline) feature in (two) other feature classes. If a vertex in this first subset touches a vertex in the 2nd or 3rd feature class, I will have to edit that vertex and update that polygon (in the first feature set). I have tried crawling through the vertices of the subset and using SelectLayerByLocation by coverting the XYZ of the vertex for use in the Select statement, but this yields unreliable results. I have tried using various SelectLayerByLocation with various "Intersect" or "WITHIN A DISTANCE 3D" cluses but the problem here is that I cannot (find a way to) release my latest selection without clearing the full selection (because I work with sub-selections from all 3 feature classes) I'm wondering if the way to go is to create a point file from the first subset, adding the vertex's OID and sequence information as attributes to the resulting point, and then JOINing by location the points to the 2nd and 3rd feature sets. Where there is a JOIN, they touch, where not, they don't touch. Then using this information to delete and manually rebuild the polygons in this first subset. All this complication is because I cannot find a way to see if anything exists at a particular XYZ location. Comments/thoughts welcome. Thanks in advance, Zoltan ... View more
