New generation of Georeferencer



Georeferencer v4 is a revolution in the online processing of scanned old maps. Matching scanned maps to the real world coordinates in a web browser has never been easier.

With feedback from the previous crowdsourcing pilots in over a dozen of countries all over the world, we have decided to reimplement our online Georeferencer tool from scratch. The new version comes with many new features, improved usability and finally, after two years of development, it is available to the public!

A complete mapping platform for old maps

The Georeferencer is now a complete mapping platform which provides the full toolset for bringing the maps from paper to screen. After the maps are scanned, they can be turned into precisely located map overlays on top of modern maps.

Redesigned interface is optimised for tablets and mobile devices. With the full-screen layout, which focuses the attention on the map, no screen space is wasted while the important tools are highlighted, and you have everything in your hand. The whole tool is collaborative so multiple people can work on the same map at the same time - similarly to Google Docs. On top of that, there are tutorials available throughout the interface so the new users can start georeferencing immediately and learn to use even the advanced features and produce professional output.


Overlay recalculated instantly

When at least three control points are placed the tool can be switched to overlay mode. The old map overlays a new map and visitors can easily add points to improve the precision of the location of the map. The map position is recalculated instantly directly in a web browser. The visitors can even switch between five different transformations and see warping results on-the-fly. 



The new “My maps” sidebar allows you to add other maps as overlays to the Georeferencer tool, which can be powerful when processing a collection of seamless maps.

Various map services are available to bring the georeferenced maps to GIS tools such as ArcGIS and QGIS, web viewers such as Leaflet or OpenLayers as well as Mobile applications. The provided map services are compatible with the Web Map Tile Service (OGC WMTS). High-resolution images are displayed via International Image Interoperability Framework (IIIF).

Online research with Compare tool

Georeferencer mapping platform also contains a new public tool that can combine maps from various institutions from OldMapsOnline. The Compare is designed for fast searching and in-depth comparison of old maps.

Several view modes are available - besides overlaying the maps you can also study them in a Swipe mode, using a “Spy glass" or you can interactively compare multiple maps in a Grid.



Try the compare tool now at http://www.georeferencer.com/compare.




David Rumsey pilot launched

David Rumsey is the first to move maps to the new version of Georeferencer. His collection of maps contains now over 47.000 images. All are available to be georeferenced at DavidRumsey.com.

OpenMapTiles: Vector Tiles from OpenStreetMap


After months of work, we are thrilled to announce a new game-changing open-source project!

OpenMapTiles (http://openmaptiles.org) provides the fastest way how to setup custom styled world maps with open-source software. In a few minutes, you can have your own OpenStreetMap tile server - ready for use in your websites or products.

Just download the pre-generated vector tiles and get started

The project turns the publicly available OpenStreetMap data into ready-to-use packages containing vector tiles for the whole planet, individual countries and major cities.

Downloaded map tiles can be displayed on websites with JavaScript viewers, used in native mobile applications on Android and iOS (even offline), or turned into traditional raster tiles or high-resolution images for printing.

There are online guides to get started.


Open Map Styles & Open Tile Schema

We have prepared a set of beautiful Open Map Styles for our vector tiles. The styles are free and open-source, and you can adapt the design and code for your project or commercial product however you like. Either use one of our map styles directly as your base map or as a starting point for your own map design. You can also use an open-source visual map style editor.

Open Map Styles compatible with OpenMapTiles Vector Tiles
Our new Vector Tile Schema is encoding the cartography decisions made on top of OpenStreetMap, Natural Earth and other OpenData sources and is 100% open and free to use, extend or build upon. We hope people will adapt, copy and reimplement our schema and data model in their projects while providing attribution.

Open-source tools and no vendor lock-in

The whole project is open-source, documented and comes with a license which is friendly even for business use (BSD + CC-BY). The project reuses existing many open-source components, map designs and open standards from the OSM & FOSS community and Mapbox Inc. The work on the new open vector tile schema was done in cooperation with Paul Norman and Wikimedia Foundation and was initially modelled after the cartography of the Positron base map from Carto (former CartoDB), with their permission.

With OpenMapTiles there is no lock-in to a single hosting platform or provider, and interested parties can adopt our workflow and do the tile generating as well as hosting completely independently and in-house. We offer a set of services and preprocessed data - including worldwide contour lines and hill shading datasets - to speed up the adoption of the project and applications in production use.

The OpenMapTiles project is a successor of OSM2VectorTiles, a project which won the OpenStreetMap Innovation Award of 2016 at SOtM in Brussels and which started in Switzerland as a student bachelor thesis at HSR Rapperswil in cooperation with Klokan Technologies GmbH.

Support and community

The team behind OpenMapTiles is available for commercial support and consulting and can assist with deployment and applications of the maps in products and services.

Contributions to the source code from the community are very welcome!

MapTiler helps people to recover from the Hurricane Matthew



The U.S. Government organization NOAA (National Oceanic and Atmospheric Administration) has chosen the MapTiler software from Klokan Technologies GmbH to turn the aerial photos taken after the Hurricane Matthew into a fast and reliable mapping service offered to the press and general public during the disaster recovery actions.

The speed of generating of the map tiles, as well as the reliability and scalability of the produced mapping service are able to handle hundreds of thousands of visitors. This is the main reason why our software is used for such cases.

Processing and hosting of the aerial photos happen on the Microsoft Azure cloud on Linux virtual machines running our latest MapTiler Pro on the command line. The tiles are served from Azure platform with an open-source TileServer software. It permits fast distribution of the maps to various mashups and websites, as well as opening of the map layers in the standard GIS software such as QGIS or ESRI ArcGIS. The same map tiles are directly reused thanks to the OGC WMTS standard. See the Coastal Imagery Services.

Other customers are using our MapTiler Pro (http://www.maptiler.com/) for similar tasks on their standard desktop computers, virtual machines, in private clouds or on Amazon or Google cloud platforms.


The maps produced by MapTiler during the previous flights are also used by pilots on the board of the airplanes together with open vector maps - as an extra option to standard navigation for taking new photos. More details are available at: http://blog.klokantech.com/2016/06/noaa-pilots-use-open-source-tileserver.html

OSMNames: Place names data & geocoder


Today we launch the OSMNames open-source project which provides a basic place search / geocoding functionality.

It is a lightweight search system powered by full-text engine with world-wide coverage. At the moment it is limited to place names like streets, towns, cities, administrative units, countries, etc.. It can be extended in future with other place types like lake or mountain names and even with POIs. The enhancement with postal addresses (house numbers and zip codes) is also possible.
Try it at:


Install the software easily together with the provided global data on your own server with the docker container osmnames-sphinxsearch. The process is described in the documentation.

The OSMNames project consists of two parts:

OSMNames data available for download

The core of the OSMNames project is the pre-processed data. It comes in easy to handle text format, the TSV (tab separated value). This allows filtering with UNIX text processing tools (grep, sed, awk, less, cut, etc.) and direct indexing via a full-text search engine.

You can download the data at http://osmnames.org/download/

It contains over 21 million gazetteer records with lat/lon location, bounding box, names in several languages, identifiers for OSM and Wikidata, etc. All the records are sorted by precalculated numerical importance (derived from Wikipedia and existing Nominatim ranking). Our website recommends how to filter the data by country, geographical location or type to create smaller extracts.

Search engine software

The project comes with an open-source server software providing a place search API suitable for a basic geocoder with autocomplete functionality. The server is written in Python and is powered by the high-performance C++ open-source full-text engine called Sphinx Search.

The OSMNames project is a result of the cooperation of Klokan Technologies GmbH and HSR Rapperswil.

Klokan Technologies GmbH is using the service in products such as MapTiler or Georeferencer. We are excited to release it now and hope more users can help us to make it even better! Hope to see OSMNames adopted by more individuals and companies soon.

TileServer GL: Maps with GL JSON styles from your server


New open-source project TileServer GL has just been released in version 1.0 at the FOSS4G conference and is available on our GitHub:

https://github.com/klokantech/tileserver-gl

With TileServer GL you can host vector tile maps on your own infrastructure, under your control, or even completely offline. The software takes care of serving the vector maps (PBFs, GL JSON styles, and all the assets), but also provides server-side rasterized tiles as a fallback.

Raster tiles look exactly the same as vector maps and are generated from vector tiles and GL JSON style on the server side with the MapBox GL Native rendering core made in C++.

The vector tiles allow for nicer maps, with a higher degree of interactivity and also decrease bandwidth to your server. The vector maps can be used in several web mapping libraries such as MapBox GL JS or OpenLayers 3 as well as native mobile applications for Android or iOS. The raster tiles can be used in almost any software including Leaflet or GIS tools (via XYZ, TileJSON, WMTS).

This way you can transition to the vector tiles wherever possible, but still have the raster tiles with the same look & feel without the need to write the map style twice in a different format.

The server can be easily set up to provide several different styles (in a modern GL JSON format), so you can have multiple maps for different use cases served from a single set of vector tiles. There are also endpoints serving static raster maps with the possibility to add polygon overlays simply by adding parameters to the URL. All the endpoints support scaling parameters so you always have HiDPI/retina, print-ready maps at your disposal.

The TileServer GL relies on other open-source projects, which have been under development for years. Most notably mapbox-gl-native, which we use for the server-side rendering and mapbox-gl-js which is default viewer for vector tiles.

This video shows in the first two minutes how easy it is to run your own map server using TileServer GL with open-data tiles downloaded from OSM2VectorTiles:



All what you need is a single docker command:

docker run -it -v $(pwd):/data -p 8080:80 klokantech/tileserver-gl

Feel free to try our TileServer GL live instance at https://maps.klokantech.com/.

It's also possible to combine multiple input sources (MBTiles; tiles from Amazon S3 or GCS; dynamic tiles from GeoServer, MapServer, ...) to create complex or even hybrid maps (satellite maps with labels). The whole stack is usable with custom coordinate systems as well!

If you are interested to know more watch the complete video recording of our presentation from FOSS4G at https://youtu.be/rOg4VnSAnI4.
