So I have 2 separate GRTS (Generalized Random Tesselation Stratified) for spatial sampling that I want to align but am having trouble even after projecting them to the same coordinate system (Projected: NAD_1983_Albers / Geographic: GCS_North_American_1983).
Any suggestions?
What were the geographic coordinate bounds for both files, prior to the projection? and what were the projection parameters you used for both
Both are the custom projection below

Wow...you central meridians are different and so are your standard parallels, no wonder they look funky. They are definitely not the same ... except for the first 2 lines ... NAD_1983_Albers, Authority: Custom
They are both Custom but that is about it.
I didn't know if I could correct the Canadian one, I end up redrawing the fishnet, the problem was that I wanted to extract the data from the original one into the new grid draw but since the polygons won't be aligned I wouldn't get matching results. I run into the problem below where the IDs get out of order.
Red is original (skewed)
Green is new grid draw trying Spatial Join to match polygons.
