There are two ways how to add maps into the search engine.
The easiest and preferred way with the most benefits. Just let us know, that you want to add your georeferenced collections into OldMapsOnline.
We can migrate all your maps and you will see the button “View as overlay” next to the thumbnail, which will point the map to the Compare tool.
The import is simple, we don't need any further information, extra data or actions taken on your side.Contact us for Georeferencer
If you are not using the Georeferencer tool, to upload your maps to OldMapsOnline, you need to provide us with an excel spreadsheet with basic information about each map. The minimum number of maps to be imported via excel sheet is 100 maps.
Each spreadsheet must have the following columns:
|id:||Your unique identifier|
|viewer:||URL to the zoomable viewer of the scan|
|title:||Title of the map|
|date_from, date_to:||Date of what is depicted on the map|
|north:||Latitude of the north-most point|
|south:||Latitude of the south-most point|
|east:||Longitude of the east-most point|
|west:||Longitude of the west-most point|
|thumbnail:||URL to thumbnail|
