GPS is for outdoor localization only, since there is no GPS signal indoor. Although there are some
indoor localization techniques, e.g. WiFi fingerprint, they are too complex to be implemented by a
small team, since you need to create a big database and implement the machine learning algorithm
by yourself. I would suggest only use the GPS APIs in Android SDK and Xcode to provide the students
with building level localization service. You may collect some GPS reading at each entrance of the
building to build a database. When the students need routing service, give them the direction and
the straight-line distance in the first version. For the next version, you may add the roads in the
campus to achieve on-road routing instead of straight-line routing.

Good morning. Thank you very much for your message and question. The mobile device based
positioning service, including GNSS (GPS), certainly could be useful to guide a new student in campus.
Besides the positioning devices, one needs to have the map resources available to make this
workable. In most university campus of Taiwan, campus map has been made by OSM (Open Street
Map) volunteers. Therefore, it is available for those app using OSM. But, at this moment, it only in the
building level, not the classrooms. I personally use Maps.me. An app certainly could be devised for
specific campus as well. For providing temporal information, a new app may be needed. Regards.
