If you don’t have a large-format, or even medium-format, printer, you can still print full-size maps by chopping (tiling) the image into smaller subsections, and then taping all those subsections together to re-create the original map in large format. I’ve posted before about several ways to do that generically, and another option that lets you tile georeferenced images to a specified scale. For generic tiling, there’s another option: PosteRazor. Multiplatform (Windows/Mac/Linux), open source, runs by itself (no installation required). A simple 5-step wizard walks you through the process:
- Select the image
- Specify the paper size, orientation and margins
- Choose the amount and orientation of the overlap, the areas that are redundant on the printed sheets to compensate for cutting/taping errors
- Select the number of pages to print the image on, with a live preview of the print layou
- Save the tiled images as a multi-page PDF document for printing (it’s very fast at this last step)
Doesn’t have all the bells and whistles of some of the other options, but for a simple tiling operation, PosteRazor is fast and easy.
