Hello, found a great tutorial (https://www.fantasticmaps.com/2012/01/tips-and-tricks-rescaling-maps-and-slicing-them-up/#comment-11414)on how to easily rescale grid maps to line up.
Quoted from the linked website.
"This map is 21.6 pixels per grid square – the wrong size for printing at home, and the wrong size for most virtual tabletops. How do you resize this so it can work in your home game?
The following works well in both Photoshop and Gimp, but can also be used just as easily in most other graphics programs:
Open up the file and select the measurement tool. In Photoshop it hides underneath the eyedropper in the tools pallet. Click and hold the eyedropper and it will open up a set of tools. Pick the ruler tool. In Gimp it’s just called the Measure Tool (shift-M to quick select).
Click one of the grid intersections and drag to another grid intersection on the same horizontal or vertical line. I tend to measure 10 squares this way, as it makes the calculation easy. Your program should now tell you the number of pixels in the 10 squares. In this case Photoshop tells me it’s 216 pixels for 10 squares (in the bar at the top of the window) and Gimp agrees (in the bar at the bottom of the window).
Now we’re going to resize the map. I want to scale the map up so that each square is 100px wide. That means the current image is 21.6/100 = 21.6% the size I want it to be. That means I need to scale it up by 100/21.6=463% (you always scale up by a factor equal to <size you want in pixels>/<size you currently have in pixels>). In Photoshop go to Image->Resize. First set the dpi to 100dpi – this will make the image print at 1 grid square = 1 inch – and then pick Percent from the drop down menu beside the Width field and enter your percentage – in this case 463%. Click okay, and your image will scale up. In Gimp, it’s basically the same. Go to Image->Scale Image. Set the x and y resolution first, and then set width and height in percent.
Throw this into your virtual tabletop of choice and you should now be able to lay in a 100px grid and have it all line up. Or you can print it off at 100% (turn off page scaling) and you should have nice 1 inch squares for your minis! It’s likely that your new scales up map will be too big to fit on one page."
