OldMapsOnline.org: Open Source & Online Tools for Old Maps
1 like754 views
The document summarizes the results of the OldMapsOnline.org project. The project developed open-source tools and online services for managing and publishing historical map collections on the web. Key results include documentation on free software tools, software like IIPImage and MapTiler that can be used to publish scanned maps online, and an online georeferencing tool at Georeferencer.org. Future plans include customizing the online tools for libraries and improving community collaboration features.
OldMapsOnline.org: Open Source & Online Tools for Old Maps
- 1. Mgr. Petr Přidal - Klokan [email protected] OLDMAPSONLINE.ORG: OPEN SOURCE AND ONLINE TOOLS FOR OLD MAPS Moravian Library Brno: OldMapsOnline.org R&D grant of the Czech Ministry of Culture (DC08P02OUK006) FOSS4G 2010 - OSGEO, Barcelona, 6-8 September 2010
- 3. PROJECT OLDMAPSONLINE.ORG • Research project of Moravian Library in Brno, Czech Republic (Bernhard Moll’s Map Collection, 12k+ scans). • Development of a workflow based on open-source software: to assist in the management, manipulation and visualization of historical map collections on the web • Best practices and step-by-step guides for use of the free software • Online tools to explore, georeference, annotate and visually integrate online old maps in a Web 2.0 style, following OGC standards and known best practices
- 4. THE RESULTS? 1.Documentation and links to free software tools, and relevant scientific articles. Presentations. 2.We have produced open-source software you can use right now for publishing your scanned maps online: IIPImage JPEG2000, MapTiler, .. + contributed patches in OpenLayers (Zoomify), GDAL (gdal2tiles), GeoTools 3.An online service: Georeferencer.org

Presentations. 2.We have produced open-source software you can use right now for publishing your scanned maps online: IIPImage JPEG2000, MapTiler, .. + contributed patches in OpenLayers (Zoomify), GDAL (gdal2tiles), GeoTools 3.An online service: Georeferencer.org
- 8. JPEG PUBLISHING OF THE SCANS 2000 • Easiest and fastest: Zoomify or DeepZoom/OpenZoom via “prerendered tiles”. Step by step tutorial: http://help.oldmapsonline.org/publish/ • Image Server software as an alternative: • For collections with thousands of images and their own hardware servers connected to the Internet • Possibly one image file for both online distribution and digital archiving (“open archive”) • Save the disk space thanks advanced compression
- 9. OPENLAYERS, ZOOMIFY, MOOVIEWER, OPENZOOM TILES PREGENERATED OR SERVED BY IIPIMAGE
- 10. JPEG IIPIMAGE JPEG2000 2000 • Free and open-source software, runs best on a Linux server • Compatible with several popular viewers (Zoomify, SeaDragon, IIPMooViewer, OpenLayers, PanoJS, ...) and iPhone or Google Earth • Easy to install (prepared step-by-step tutorial and a Debian package) • Alternative to commercial products such as Lizardtech ExpressServer (MrSID), ERDAS Image Web Server (ECW) • Direct distribution of TIFF images (with encoded pyramid) • Support for JPEG2000 format (via Kakadu library - non- commercial use only, 100% free OpenJPEG library later on)
- 11. 400 DPI 9606 x 7322 px 202 MB uncompressed TIFF ~107 MB JPEG2000 (lossless) 15 MB JPEG 85% ~ 8 MB JPEG2000 (lossy)
- 12. JPEG IIPIMAGE JPEG2000 2000 • Considering to use JPEG2000 format for archiving? • Do you want to publish high resolution images online? • Have a look at our open-source project! • Documentation, best practice articles related to encoding to JPEG2000, software for download: http://oldmapsonline.org/jpeg2000/
- 32. PUBLISHING OF THE MAPS • Easiest and fastest: prerendered tiles via MapTiler: http://www.maptiler.org/ • Alternative to map servers, which are harder to install/ configure/maintain: • MapServer, GeoServer, ... • Available on the OSGeo LiveDVD! • It generates OSGeo TMS tiles, same like GDAL2Tiles.

Presentations. 2.We have produced open-source software you can use right now for publishing your scanned maps online: IIPImage JPEG2000, MapTiler, .. + contributed patches in OpenLayers (Zoomify), GDAL (gdal2tiles), GeoTools 3.An online service: Georeferencer.org
- 34. Technology Preview: ONLINE SERVICE GEOREFERENCER.ORG
- 35. WHAT IS IT? • Online tool designed to bookmark, georeference and annotate high resolution images of maps on the web. • Collaborative Web 2.0 online service for all of us! • You can create your personal virtual map collection and do a research and genealogy studies online. • Share the results of your work with online old maps, compare and synthesize maps published at different websites • Automatic 3D visualization and overlays of Google Maps-like base maps • You need only a web browser to process the maps!
- 36. DEMO http://georeferencer.org/ Still under development! PUBLIC ALPHA VERSION AVAILABLE NOW!
- 38. PLANS FOR THE FUTURE: • Customization for libraries, adding of metadata. • Clipping, composites of maps, correct merging of map series • Map projections and custom coordinates (EPSG) • Reference maps via OGC WMS - from national authorities • Closer integration with library websites (via a link) • Improvement of the community services, comments, links to research, etc. • Image analysis: “colored version of ...”, automatic neat line detection, cropped maps and derivatives, deduplication • A free service, hopefully a new grant (MZK + CUNI + MU)
- 39. WE NEED YOUR HELP! • Try it and submit “feedback” via the online button! • Ideas for improvement? Do you want to collaborate? • Developers? We have a REST API to access the data. Need for JavaScript API for development of external tools? Please contact us, feedback wanted! http://georeferencer.org/ Support for all JPEG images, Zoomify maps and David Rumsey’s maps with and an improved georeferencing interdace now! Support for more formats of maps coming soon!
- 41. GEOGRAPHICAL SEARCH • Intuitive interface: Where, When, Who, What • Ranking to sort the maps, even in a large catalog • Tested projects: • TimeMap.net - (ECAI.org) • Alexandria Digital Library • DigMap.eu Lucene GeoTemporal (LGTE) • Google GeoSearch API
