All,
I'm hoping to tap into the python community for advice on how to efficiently convert a shapely linestring back into an arcpy polyline. I am developing a suite of python tools in the ArcPro 3.1.0 toolbox (atbx).
So I read from a file geodatabase polyline geometries and convert them to a shapely linestring. I do this as shapely exposes a useful method on a polyline that does not exist in the arcpy. A simplified snippet of my reading code (which works fine) is shown below:
from shapely.wkb import loads
with arcpy.da.SearchCursor(mylayer, ["SHAPE@WKB"]) as cursor:
for row in cursor:
geom = row[0]
line = loads(bytes(geom)) # Convert arcpy geometry into shapely geometry
# Do something with line using shapely
Later on in my code I want to write the processed shapely linestring back into a new Feature Class using an insert cursor.
What I cannot work out, hence me coming to you, is how do I efficiently turn a linestring back into an arcpy polyline geometry so I can write it back to a new file geodatabase feature class? In the help file the arcpy polylines take arrays of points when constructing a polyline. I was expecting to find the reverse of the WKB property on a polyline? It seems to me that arcpy allows you to convert from a polyline into alternative ways of recording geometry (json, wkb, wkt) but does not seem to consume them?
