The blog of the Library of Congress’s Geography and Maps Division isn’t the first place you’d expect an explanation of the GeoTIFF format (basically, an image file in TIFF format that includes georeferencing metadata, so that the image can be projected on a map grid). But georeferencing old maps so that they can be placed on a modern map grid is definitely a thing, and Carissa Pastuch’s piece, “The Secret Life of GeoTIFFs,” looks at GeoTIFFs through the lens of an experimental dataset of georeferenced late 19th- and early 20th-century Austro-Hungarian maps.

An Austro-Hungarian Mapmaking Guide

The Bodleian Map Room Blog posts some excerpts from an 1882 Austro-Hungarian guide to mapmaking. “The Schlüssel und vorlageblatter für den situations zeichnungs unterricht (which translates roughly as ‘Key and template for drawing lessons’) is a teaching aid created by the Institute of Military Geography in the Austro-Hungarian Ministry of War in 1882 for the drawing of maps. Inside there are a number of different terrain examples and sheets showing scales, text, topographical features and legends.” As the blog post points out, the purpose of the guide was to ensure uniformity in military mapmaking.
