Which Spatial Index ArcGIS Pro uses? And where can I find it?

barrylim

Hello, I read an article and it said that ArcGis uses a spatial index for spatial queries, now I want to know which Spatial Index it uses (B-Tree, SP-GIST, GRID) and where I can find information about it. Does anyone know something about it?

article:

https://resource.esriuk.com/blog/processing-big-data-using-small-data-techniques/

especially this part:

"Within ArcGIS, if you display or query data in a File Geodatabase you are using Esri’s spatial index implementation. If your data is in Oracle, SQL Server, Postgres or SAP Hana, then typically ArcGIS will use that data store’s native spatial index rather than its own, making spatial queries as rapid (or almost as rapid) as attribute queries."

I found this help page for ArcGIS Pro that discusses types of Spatial Indexes as they relate to DBMS's and grid based indexes. Hope this helps!

Thank you for your reply! So it seems like it depends on the data source. If I for example import a shapefile into a file geodatabase it should use a grid based spatial index right?

That's my understanding if you import a shapefile into a fGDB.

If you feel my answer is the correct answer, you may close this thread my marking "Accept as Solution" - have a great day!
