In first image is a fishnet polygon. Using 'Polygon to Raster' tool, at SAME CELL SIZE of fishnet. I get image 2 (only few pixel shown to highlight misalignment).
Is it possible to convert to raster such that it aligns with fishnet.
Possible Solution based on above comments.
As per suggestion, I tried to set extent same as fishnet polygon, however the error stayed the same.
However I have another raster already with same pixel location. Selecting 'Snap Raster' to this raster in environment solved the problem
