Abstract. Digital geographical maps have become an important part of many websites and mobile applications. For example, we can embed a map and geo-location tracking into a web page, or into a smartphone application. Nevertheless, the management of user maps and routes is different between the many competing geographic information services. We designed and implemented an open-source and linked-data web service for facilitating the process of a map and route management. The implementation of our open-source web application has been built on-top of existing web services that provide maps. In this way, the Mapito.org service provides an open abstraction layer above the proprietary implementations of commercial companies. Notably, the Mapito platform provides an Application Programming Interface (API), which facilitates the creation and editing of a map and the ability to download the data, or routes without visiting the Web-based user interface. In this paper, we outline the system and provide representative case studies.
