MapTiler was one of the companies pioneering map tile implementation. It started as an
open source software product in 2008 used by libraries to turn digitised paper
maps into
tiled web maps. MapTiler converts data into tiles that can be used as a
slippy map on a website. A set of tiles is created for each zoom level along with an
XML file. By 2018, MapTiler had become a maps
API with the capability of providing ad-free personalised maps in both online and offline environments. These developments along with the inclusion of
satellite imagery from
Sentinel-2 and
Airbus led to them being winners of the Airbus Multi-Data Challenge organised as part of the Copernicus Masters 2018. ==Data sources and technology==
