Toponym-assisted map georeferencing: Evaluating the use of toponyms for the digitization of map collections

Karim Bahgat, Dan Runfola, Claudionor Ribeiro da Silva
2021 PLoS ONE  
We find that toponym-based georeferencing is sufficiently accurate to be used for data extraction purposes in nearly half of all cases.  ...  A major barrier to such map digitizing efforts is that the geographic location of each map is typically unknown and must be determined through an often slow and manual process known as georeferencing.  ...  Evaluating the accuracy of toponym assisted georeferencing In order to evaluate the accuracy of toponym-assisted georeferencing, we engage in two exercises.  ...
