This is the map I rectified.
Did this process change your understanding of the spatial DH projects you explored earlier?
Yes, georectifying a historic map transforms how spatial digital humanities projects interpret and analyze historical geography. By aligning an old map with a modern one, we can directly compare past landscapes with present-day geography, revealing changes in urban development and environmental shifts. This process provides deeper insights into history and geography, enhancing our understanding. Moreover, it makes historical maps more interactive and accessible through digital platforms, fostering public engagement with spatial history.
Examine the This Map page: what formats can you access the map you rectified in?
On the This Map page, I found that the map can be accessed and used in GIS apps and exported in GeoTIFF and IIIF formats.
What possibilities do you see once you have a georectified map? What would be next steps?
Once a historic map is georectified, it opens up numerous possibilities for spatial digital humanities research. We can overlay it with modern GIS datasets, census records, archaeological findings, or environmental data to analyze and reveal historical transformations. This comparison can aid studies on urbanization, environmental change, and cultural shifts. Additionally, georectification makes historic maps more interactive and accessible by allowing them to be uploaded to websites and apps or exported in different formats.
Are there problems with georeferencing that you should consider?
Yes, several challenges and potential problems arise when georeferencing historic maps. These maps were often drawn with different projections, scales, and levels of accuracy, leading to distortions when aligning them with modern maps. In the map I rectified, many cities are marked with just a single point, which could result in inaccuracies when matching them with present-day locations. Moreover, some landmarks on the old map have changed. For example, some cities have been renamed and cannot be found on the modern map. Additionally, geographic features such as rivers, coastlines, and land boundaries may have shifted due to natural or human-made changes. All these factors should be taken into consideration.
What research questions or areas would this method NOT be appropriate for?
Research on regions and time periods that lack reliable data may result in inaccurate maps, making georectification challenging. Also, this method is not appropriate for studies requiring high precision, considering the limitations mentioned in the previous question.
