I have a set of georeferenced rasters that I want to combine in a seamless layer in QGIS. I believe what I have to do is clip them by mask layer and then build a virtual raster. There is an issue however. The original maps that I have scanned have zero overlap, so each one starts exactly where the other one ends. What do you think would be the best course of action here:
- include the neatlines in the clipping mask - then my eventual map will have black lines along the seams
- exclude the neatlines - then there will be gaps up to 10 pixels wide - is there any good way to fill them?
- any other suggestions? maybe I am approaching it from entirely wrong angle?
By the way, is there by any chance a tool to trace the neatlines automatically instead of painstakingly drawing the clipping polygons manually?
