I'm quite a newcomer when it comes to map data.
I have an Illustrator map, drawn by myself, with different polygons (regions, country, ...). In Illustrator I know 100% that the region and country line are perfectly in the same position.
I then used MAPublisher to export these to KML files, to then convert them into GeoJSON files.
I use these GeoJSON files together with Leaflet to generate polygons in the shape of what I have drawn in Illustrator.
But as you can see in the following picture, when I zoom in, the lines of regions and country are not in the same position.
Any ideas why this is the case?
