T hiessen Polygons / Voronoi Diagram and Delaunay triangulation. Pick your discipline. Delineate space around points. Design stained glass patterns even (Use a Voronoi diagram) A basic GIS functionality, for those of us that work with geometry. An Advanced license is required. Soon... part of the "Free Tools" movement or if you like... "Free the Tools" movement. GitHub - Dan-Patterson/numpy_geometry: A numpy geometry class and functions that work with arcpy and ESRI featureclasses How is this accomplished? By using tools that are already available in scipy.spatial 's Delaunay and Voronoi, A little numpy-based geom (npg) functionality, a dash of arcpy and arctoolbox tools and you have it. The Voronoi results obtained from Create Thiessen Polygons—Help | Documentation and from npg. are shown in the figure below. It doesn't really matter which is which since they identical in shape and area. Note: The esri tool buffers by an extra 10% by default, the npg version defaults to the input extent, so ignore the "to infinity" polygons on the edges I like Delaunay triangulation for shapes. The figure below shows a such a triangulation performed on a variety of shapes, using the npg Delaunay option. You can generate your own art or derive medial axes/skeletons from these. So next time time you think of Thiessen or Tin.... think how you can "Free the Tools".

ArcGIS Pro 2.6 Beta 1 (sorry, no 2.5) arcgis module installed in the base installation (ie, no clone) numpy, pandas and the rest are already installed. I didn't install geopandas, so I can't help you with the geometry

Caitlin Casey That is an external product to Arc* https://www.arcgis.com/home/group.html?id=4ff5d72c236c479aa8cf6d55ce9df1ec#overview You might want to show what your final product and inputs look like

Buffer—Help | Documentation The steps would require you to separate your segments into those that have an equal buffer on both sides then those that have differential side buffers. Buffer the left using the value from one field and buffer the right using another field is one option. Then you can merge the files together. The above steps would require select by attributes to do the separation of the parts.

I use numpy (which pandas largely depends on) for all my shape and attribute work. Point geometry is easy with FeatureClassToNumPyArray. Attributes are a snap with TableToNumPyArray. The attribute column extraction is the same someArray['SomeField']. I have many, many blog posts on numpy's use in GIS Py... blog They are ones I wrote in my previous incarnation as a faculty member before I retired. My new incarnation posts ArcGIS Pro and numpy tools at

They seem to give examples where it is possible. I use scripts. Perhaps export the models to scripts then combine the resultant might be easier

the "origin" if you want. But you would still have to provide those two values, since in many disciplines, the "origin" is taken to refer to (0, 0) without any extra modifiers.

they are the proper terms allthough central meridian is also referred to as the longitude of origin Some references https://epsg.io/28191 Palestine grid - Wikipedia Transformation between GNSS coordinates and Palestinian coordinatessystem in West Bank Coordinate systems, projections, and transformations—Properties of maps | Documentation and https://www.esri.com/training/catalog/57630434851d31e02a43ef5a/working-with-coordinate-systems-in-arcgis/

those are the bugs I sent in the list. If yours isn't there, perhaps no one has reported it, so you should contact Tech Support so they can walk you through tests to see if it is a bug

Make sure you send the report (it is done for you). Bugs on that search phrase disable network topology https://support.esri.com/en/Search-Results#search?q=disable%20network%20topology&content-type=Bugs To search for your own bugs Search on ArcGIS Technical Support changing the language to one of your preference.
