I have a grid of squares which are not aligned N-S, E-W.

These are 5m squares, but I've been asked to reduce these to 1m squares.

Therefore I need to sub-divide one square into 25 squares on the same grid orientation as the 5m square.

I have access to ArcMap.

Below is an example, showing the 5m sqaures split into 9 sub divisions.

enter image description here

    Can you add a screenshot? Pick either ArcMap or QGIS or your question might get closed (pick QGIS). Probably easier to create a new 1 m grid and join your data to it – BERA Feb 08 '22 at 13:03

    This is pretty easy with ArcPy (dirt easy if the polygons are really quadrilaterals), but you need to choose a stack first. – Vince Feb 08 '22 at 13:55
  • They look like perfect squares, area is 25.00001 to 24.99995 I assume because the grid was rotated. Despite preferring open source, let's go with ArcMap as the focus. – Spatial Digger Feb 08 '22 at 14:34
