I'm using ArcGIS 10.4.1. I need to create a grid that will allow me to join spatial data to cells, while also aligning with 15 minute marks on the perimeter. My biggest issue is the spacing between the latitudinal lines going south. I cannot get my fishnet to line up to the 15 minute marks, the grid is always just a bit off. Projection: WGS 84.
Is my projection incorrect? If so, what should it be?
Is it possible to create a fishnet with grids ever 15 minutes?
Do I need to reproject my fishnet to align to my 15 minute data frame grid? and if so, how do I reproject it?
Can I save my data frame grid as a shapefile or feature class to join spatial data to it?
