Title: Historical Map Annotations for Text Detection and Recognition
Description: This data is set designed for testing the performance of text/graphics separation and character recognition algorithms on text in scanned historical map images. Thirty one maps from the nineteenth and early twentieth centuries (1866–1927) were chosen from nine atlases in the David Rumsey Map Collection (http://davidrumsey.com). Most maps are of individual U.S. states, though some are regional and one is of the entire U.S.; most feature little handwritten text. The original MrSid files are converted into uncompressed TIFF images for a manual annotation, stored in JSON format. The authors gratefully acknowledge the David Rumsey Map Collection as the source of the map images, which come with the following notice: Images copyright © 2000 by Cartography Associates.
