Hi,
For a university project I am trying to create a scoring framework based on climate indicators and visualise this on Tableau. Since I don't have access to any reliable reverse geocoders, I downloaded a .shp file with all level 1 administrative boundaries and did a spatial match with my climate data (which has a very long list of centroids covering the globe). My issue is when I do the spatial match, the data that comes out of it is equal to 3GB, and I can't output the matched polygons to a shapefile as it says that the file exceeds 2GB. To address this I've kept lowering the maximum number of rows per file and still got the same message. I even output the polygons as a .gdb file and after 5 hours, it outputted a 440GB folder. When I split my outputs I manage to download all of the centroids and attributes, but I need the polygons for when I begin visualising as the centroids only show points all around the globe while I need them to be concentrated and filled in each individual State/Province.
I hope I wasn't confusing and happy to clarify. I also attached a screenshot of part of the workflow which might be helpful.
