How to get a defined boundaries of a masked grid?

SyifaSukri

Hello everyone,

I masked my grid using a polygon to only include my area of interest, AOI (within the polygon). However, the grid boundaries are not well-defined. My polygon is rectangular but the masked grid has irregular or 'zigzag' outer boundaries. Is there a way to get these boundaries clear (shaped as rectangle instead of irregular)? I do think that it is caused by a small AOI over the largely spaced survey line spacing. But maybe there's a way to make it better?
