Georeferencer for Leiden University

In Leiden University, over 300 of hand-drawn manuscript maps from the collection Van Keulen have been georeferenced in the new pilot. The maps were drawn between 1704-1755.

After more then 300 years it was quite tricky to place the control points, as nearly all places are using different names and on some places the landscape shape was changed significantly as well.

OldMapsOnline - new version released

OldMapsOnline is a search engine for maps that allows visitors to explore and discover the beauty of historical maps depicting a past geographical place of their interest. 

In the new version released in July 2015, additional maps have been added and the website already indexes over 400,000 scanned maps from collections of The British Library, National Library of Scotland, David Rumsey, Harvard Library, Dutch National Archives, Charles University in Prague, New York Public Library and other institutions worldwide.

It is a well-known project in the cultural heritage sector. From its first launch in 2012, the website has had over 1,500,000.  OldMapsOnline provides a single entry point for searching maps of the same geographical location without the need to know which library holds the actual map. This is a real benefit for researchers and students because it saves their time, effort and costs.

Georeferencer for State Library New South Wales

Glad to see another Georeferencer project for State Library New South Wales in Australia. The tricky part of this project were significant changes in names of the streets, which needed the contributors with local knowledge.  

Over 900 maps were successfully placed and the obtained data enriched the library catalogue with geographical locations. More information about the project is available at http://www.sl.nsw.gov.au/using/map_georeferencing.html


Garmin GPS: Create a custom map with MapTiler

To create a custom map was never so simple. MapTiler converts your map into the high resolution format compatible with Garmin handheld GPS devices.

You can very quickly import any map in only 3 steps:

1) Use MapTiler to create a map from any image
2) Pack the result into .zip archive and rename to .kmz
3) Upload the map into your Garmin handheld device

Why not use Google Earth overlay?
Compared to the traditional way recommended by Garmin, this approach has several advantages:
  • you can import larger maps
  • the georeference is much more precise, mainly on large areas
  • the process is faster

Just follow the tutorial at

Produced maps are compatible with following devices
