About us

We are a swiss software company dedicated to the development of programs and systems
around public transport, particular extremely fast nearby-searches.


We are developing and operating the website https://www.arrlee.ch. Arrlee enables searching for points of interest such as hotels, museums, hikes etc. in your vicinity by using public transport. For a short demonstration see the demo video.

The Arrlee-Engine can be licensed for use on your website or – for easier integration – a travel time matrix can be purchased.

borderextract is an osmosis-plugin we released as open source (MIT-License). With borderextract you can easily export administrative boundaries as polygons from an Openstreetmap dump. Export formats are KML (keyhole markup language, used for example by Google Earth) or SQL (MySQL-Spatial-Dialect). Particular the sql-export into a spatially enabled database makes it possible to query for the administrative area (village, district, state, country etc.) of a given coordinate. Find more information on our borderextract-page.
