Quality control review process
OldMapsOnline Georeferencer is a powerful online tool that allows users to assign geographic locations to scanned historical maps and help map libraries retrieve important metadata. Once georeferenced, the entire map collection becomes geographically searchable, offering a new way of discovery for researchers, students, and the general public.
To ensure that the maps are georeferenced correctly and the metadata is correct, a review process is used to check the quality of the georeferencing work done.
Steps of the Review process
Assigning the "Reviewer" role
Log into georeferencer.com with your administrator email and go to your institution georeferencer website
Go to menu “personnel” and fill in the reviewer email address
Choose position “reviewer” and then click on “add person”.
Reviewer role is added.
Where to find maps for review
The person assigned as the "Reviewer" will see the "Review" section in the hamburger menu; clicking on it will open the dashboard.
On this dashboard, you can review a random map or a map from a specific collection. You can also see top reviewers and progress statistics.
After clicking on a review, a familiar georeferencer view appears side-by-side, and the reviewer can review the assigned points and adjust them if necessary. Of course, you can also use overlays, coordinates and, importantly, clip control.
Each map has in Georeferencer under "Coordinates -> Transformations -> Default Transformation" the option to set the transformation method used when exporting rasters to WMTS or GeoTiff.
During the review process, the reviewer needs to decide for each map which is the suitable transformation method for that particular map - make the decision and confirm it.
