Make Table View Tool and Displaying Geometry Points

ChuckBenton

I need to create a table that explicitly displays the points that define a polygon boundary. Make Table View comes close, but the Shape field simply displays "Polygon". Is there a tool which outputs a list of points for each polygon?

So it was curves that was the issue. Besides that all is well. thanks for the help!!!

You have to convert it a point file to get the point values

Feature Vertices To Points (Data Management)—ArcGIS Pro | Documentation

Then you can use the field calculator or

Add Geometry Attributes (Data Management)—ArcGIS Pro | Documentation or

Add XY Coordinates (Data Management)—ArcGIS Pro | Documentation

to add the coordinates to the table

Thanks Dan. Headed out momentarily and will try this in the AM. I suspect the geometry details (such as multiple polygons in a parcel) get lost... looking to generate something like:

Longitude	Latitude	Geometry
-89.0259	38.09963	POLYGON ((-89.0237086 38.1015136, -89.0234627 38.0976878, -89.0235319 38.097689, -89.028015 38.0977517, -89.0280308 38.0977518, -89.0283478 38.1015333, -89.0237929 38.101514, -89.0237781 38.1015139, -89.0237086 38.1015136))
-89.023917	38.120071	MULTIPOLYGON (((-89.0231767 38.1177508, -89.0237414 38.1164201, -89.0247357 38.1164507, -89.0247523 38.1164509, -89.0248053 38.1164514, -89.0248041 38.1177957, -89.0247511 38.117794, -89.0247345 38.1177935, -89.0231767 38.1177508)), ((-89.0231767 38.1177508, -89.0231754 38.1191253, -89.0247331 38.1191616, -89.0247498 38.1191621, -89.0248028 38.1191635, -89.0248013 38.1199945, -89.0248007 38.1200951, -89.0247478 38.1200951, -89.0247315 38.1200952, -89.0247314 38.1200952, -89.0222174 38.1200228, -89.0231767 38.1177508)))

Any Suggestions?

DanPatterson

Ugly but doable

ChuckBenton

Interesting. I don't recognize the screen you captured... from Pro?

ChuckBenton

I found it... ignore the previous. That said, I take my selected area, create a new field called GEOMETRY, run the calculate field, and get (null) results. Ideas?

little s not S look carefully at my expression... case-sensitivity... I typed and didn't select the "Shape" from the list... learned the hard way 😉

ChuckBenton

I'd done the small 's' first... same result...

Not sure what to make of it...

No clue why yours isn't working...

polygon featureclass in a file geodatabase (so network-thing or web-thing)
- simple polygons, no curves or circles....
  - maybe WKT doesn't handle curves well... densify the fc if you do)
Text field... WKT field name (maybe GEOMETRY isn't a good field name)
do the field calculation watching for the small 's'

See the image.

Alternatives that I normally use... TableToNumPyArray with "explode to points", reassemble the table geometry in NumPy and export to another format

yes curves and multipart shapes aren't handled well by manythings. I normally check geometry properties when working with polylines and polygons. For instance, a simple field calculation can flag stuff that isn't necessarily visible to the eye

For Polylines, for instance... Polyline—ArcGIS Pro | Documentation

hasCurves (Read Only) Returns True if the geometry has a curve. Boolean
