Make Table View Tool and Displaying Geometry Points

ChuckBenton — Wed, 01 Sep 2021 19:02:53 GMT

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?

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?

Ugly but doable

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

Re: Make Table View Tool and Displaying Geometry Points

ChuckBenton — Thu, 02 Sep 2021 18:33:36 GMT

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 😉

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

Not sure what to make of it...

Re: Make Table View Tool and Displaying Geometry Points

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

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

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
