The British Library Georeferencer: new 2800 maps!

In these days you have the unique opportunity to get involved and help the British Library to georeference new digitized maps, which were selected for scanning and online publishing recently.

Nearly 2800 maps are now available online and waiting for georeferencing. It is really easy process.

See this video:

and start at:  http://www.bl.uk/maps/

This release has implemented new functionality for use within social media, including better personalisation and visualisation options. It is possible to compare two old maps and create a personal map collection with the new "My Maps" function.

Klokan Technologies also prepared new Facebook application for georeferencing maps from the BL, you can participate and in the same moment compete with your FB friends: https://apps.facebook.com/georeferencer/

Moreover, involved contributors can choose from two different collections of maps, which were selected for release:

First collection represents maps of British and Irish towns and its fire insurance plans (2500 maps). This collection provides information, which you will not find somewhere else, not just about the land use, buildings, but also about the urban landscape in the late 19thc - 20th century.




Second collection consists of military maps from the World War I and US Civic War (225 maps). Among these maps you can find trench maps, campaign charts and also ethnographic mapping.

Each contributor will see his/her details and the best contributor will be publicly announced.

WebGL accelerated Georeferencer presented on ICA conference in Rome


On ICA conference in Rome (19-20 Sep. 2013) Hynek Pridal from Klokan Technologies presented integration of Polynomial and Thin plate spline transformation into Georeferencer. Those are more accurate for some of the use cases. Up to now this was done only with special map server software with OGC WMS needing installation on the local server. Now it is possible using html technologies such as .HTML5 Canvas, SVG or WebGL which means no installation on your server and no troubles consequently.

WebGL allows hardware accelerated graphical operations on a web page. A graphic card of your own computer is utilized and therefore the overall performance is much higher then experienced ever before. Maps appears faster and there is no need to store georeferenced and non-georeferenced copies of the maps separately - so it is possible to save on the digital storage as well.

TileServer: WMTS from map tiles and MBTiles

Do you want to host your maps online according the OGC WMTS standard? Did you know you can do that from an ordinary PHP web hosting?

Your maps could be used on the web and in mobile devices, but also opened in ArcGIS for Desktop from ESRI or in the open-source QGIS and other desktop GIS clients and systems. There is no need to install any special server software such as MapServer or GeoServer to achieve this.

On the 26th International Cartographic Conference in Dresden, Germany we have announced a new TileServer project which allows exactly this.

The presentation contains a step-by-step guide how to convert GeoTIFF or other raster geodata files into tiles and WMTS online endpoint.
Any ordinary webserver is supported  - no need to install additional server software - so the publishing process is extremely easy and the maps are very fast.


The TileServer comes with a nice JavaScript interface showing the list of the published maps, sample viewers in Google Maps, Leaflet and other web libraries including copy&paste ready code. Both tiles in a folder as well as the MBTiles are supported.

There are also step-by-step guides for desktop GIS software which is supported:
The maps are of course usable with:
  • Web mapping via Google Maps API, Leaflet, OpenLayers, MapBox.js via TileJSON
  • iOS mobile devices (iPhone/iPad) via MapKit or RouteMe
  • Android tablets and mobile phones via OSMDroid and Google Maps Android API
Check the presentation and feel free to download and try the open-source TileServer-PHP project.

To convert your geodata into tiles you can use our http://www.maptiler.com/.

The Bounding Box Tool described by the Harvard University Library

Marc McGee from the Harvard University Library has written a great step-by-step guide on how to use the Bounding Box Tool developed and maintained by Klokan Technologies GmbH.

The practical online tool for (not only) map librarians is freely available at the address http://boundingbox.klokantech.com/ and it allows visual selection of geographic coordinates for direct copy&paste into a library system during cataloguing in various formats such as MARC, DublinCore, CSV or KML.

The article has been published in the recent issue of the »base line« newsletter (Volume 34, Number 3, June 2013, ISSN 1943-6548) in the section »On the cataloging/cataloguing front« edited by Tammy Wong from the Library of Congress.

Base line is an official publication of the American Library Association’s Map and Geospatial Information Round Table (MAGIRT).

The complete text is open access and freely available online at: http://www.ala.org/magirt/sites/ala.org.magirt/files/content/publicationsab/baseline/34_3.pdf

We are keen to further develop such online tools in future and help with the geospatial search applications in large map catalogues and with community engagement through our Georeferencer and MapRank Search technologies.

It is really a pleasure to see our work appreciated by many map librarians all over the world!

Map overlays with WebGL: affine, polynomial, TPS transformations in JavaScript with GLSL

A new approach on how to overlay high-resolution images on top of online slippy maps (such as Google Maps, OpenLayers or Leaflet) has been introduced by Petr Pridal from Klokan Technologies at ETH Zurich (one of the world’s top technical universities) during the conference The Graphical Web 2012 / SVGOpen 2012.

The HTML5 and WebGL technology enables on demand calculation of various overlay transformations (affine, polynomial, TPS) for high resolution zoomable maps or large raster data (such as aerial photos) directly in a web browser - immediately, with instant response for an user interaction, as demonstrated in http://vimeo.com/50144414.

Technically it is an viable and scalable client-side alternative for traditional server-side services such as OpenGIS WMS or WMTS for some specific use cases.




This technology will soon be integrated with the Georeferencer online service - to be available to general public on the high resolution maps published in the David Rumsey map collection or in the British Library as well as other institutions using this service which allows to turn scans into true maps with a few clicks inside of a collaborative online interface.

The warping technology may be integrated with other third-party systems - desktop, server or mobile applications with OpenGL ES 2.0 compatible GPU. Support for transformations between custom map projections is also on our roadmap.



The record of the complete presentation is online.


This technology complements the MapTiler Cluster product, the significantly improved version of the popular open-source GDAL2Tiles utility for generating map tiles suitable for cost effective and scalable TMS and OpenGIS WMTS compatible map publishing from any cloud storage or a traditional Apache+PHP webhosting, practical for Google Maps API mashups and for native mobile applications (iPhone/iPad/Android) utilizing Apple MapKit, RouteMe or OSMDroid.

British Library: 3rd Georeferencer pilot announced

Using Georeferencer software from Klokan technologies, another 800 items have been selected for the Georeferencer Project from the British Library’s collection of over 4.5 million maps. The last time the British Library undertook such a project 708 maps were completed in less than one week.

It’s easy to use and highly addictive – and a fascinating way to explore the past while improving the information that underpins our digitised collections. This project brings together people’s passion for maps and history with the latest online crowdsourcing tools,” says Kimberly Kowal, Lead Curator of Digital Mapping at the British Library. 

As a result of these previous successful rounds of public crowdsourcing, those maps are now spatially enabled, allowing users to search and navigate maps online. Maps from previous rounds are accessible through the Library’s Old Maps Online portal developed by Klokan Technologies.
