Collaborative Indoor Mapping in a Spatial Data Management Context

The objective of this thesis was to research on collaborative geospatial data management, how to share, store and process data between different actors, of different natures and different purposes. This research work will serve as base for the implementation of a web-based collaborative map editing application for the company Nimble Devices Oy, and to be partly published as a free licensed software. The geospatial data is being stored as generic geometric objects in a PostgreSQL database. Every data processing will be represented as an ``Action`` object containing all the required informations to replicate the same data processing on any other actor of the whole system. The ``Action'' objects are transmitted to the database through an application programming interface on the server side, and will be transmitted to the other web clients with the Javascript library TogetherJS. This thesis will present background research and a literature review on the topics of geospatial data and indoor mapping. Then a specification and conception work will be done to suggest solutions for the previous problematic. The thesis then presents some technical validation and results of the project. And finally, a simple conclusion including the future works, and future possibilities related to this work
