Compare results of geopandas with Arcgis

Perform the overlay task on Arcgis with the same data we used here to double check our result.

How to submit an issue?

• Have you checked previously open/closed issues to see if your question has already been asked & addressed?
  • If there is an open issue similar to your issue. Comment on that open issue with additional detail indicating that you too are having the same issue. This allows the project sponsor to prioritize incoming issues.
• Have you provided a clear description of your issue so that the project sponsor is able to answer all your questions with as few back-n-forths as possible?
• (Please acknowledge by checking this box) If a screenshot or visual helps better communicate some complex idea, have you provided one?. Draw.io and lucidchart are some excellent and quick drawing tools.
• (Please acknowledge by checking this box) When an issue is resolved, please post the steps to resolution or clearly describe the resolution before marking the issue closed.

• Have you been kind, courteous, and considerate in your questions?
• Have you considered using Stackedit.io, a handy tool to quickly write in markdown?

The result of spatial_overlay is not exactly the same as the result generated from Arcgis. I found some similar concerns regarding doing overlay on large datasets.

Do you think this difference is acceptable?

Thanks @lingyielia - please prepare to demonstrate this on our next meeting.

Compare the performance of spatial_overlay, qgis, and arcgis

• Algorithm: spatial_overlay = qgis ≠ arcgis
• Speed: arcgis > spatial_overlay = qgis
• How they deal with 'invalid geometries': arcgis (handled somehow by itself), spatial_overlay (set a buffer of 0 to make the geometries valid), qgis (throw error)

For more information, see the discussion at the end of here.

Closed because this is beyond scope of this particular project but something that we need to look at in the future

@vr00n , These are Data with Invalid Geometries. If you need any further information, please let me know.

Hi team any objections to closing this issue? Doing some housekeeping
