Hello guys,
I've been making a hand made map in photoshop for a long while, and I'd like to know which is the best method and software to "interpolate" a tiled heightmap. If it exists.
For me, the ideal outcome would be if the program could made smooth transitions between such contour lines, where the slope varies depending on the distance and height between contours, and also respecting those contours avoiding modifying them. In such a way that the map is ready to add the final details in wilbur.
Like this...



I am mainly interested in it being an automated method because the map is huge.
This is a piece of said map.



Best regards.
