Rather than distributing actual large-format posters via mail, we now offer several poster-sized and wall-sized high-quality maps in the Adobe PDF format distributed on CD/DVDs. All PDFs are designed to be printed on high-quality large-format plotters and cannot be edited. The user may print these out on their own large-format plotter or take the media to a 3rd-party vendor such as Kinko’s. Users may choose to laminate and treat their posters to protect it from scratching and UV radiation. These maps are all original creations by Paul Wessel using GMT scripts and Geoware tools. The resulting PostScript plots were converted to PDF and are limited to printing only (no editing/copying). To achieve the highest image resolution, the 30×30 arc second GLOBE30 topography and Smith and Sandwell’s predicted bathymetry grids were specially processed with GMT and proprietary Geoware tools and resampled at the final pixel resolution (300 dpi) in the map projection used for each map. Tectonic maps have high-quality relocated epicenters based on the dataset of Engdahl et al  and Holocene volcanoes from the Smithsonian Institution data set. Shipping/Handling charges include Worldwide Airmail shipping of the CD/DVDs. We recommend you order and pay using your credit card with the above free PayPal service, available from most countries.
