Architecture for Including Personalization in a Mobile GIS via Semantic Web Techniques - Geographical Information Systems: Trends and Technologies - page 233

We created a routing algorithm from scratch that works effi ciently
running locally in a smartphone device and it is scalable until distances up
to 1 km. The algorithm uses a backtracking function with some heuristics
that improve effi ciency and reduce memory requirements, in order to work
on a smartphone device. For a deeper explanation see (Descamps-Vila et
al. 2012b).
Proof of Concept: Itiner@
This section presents the final product developed considering the
architecture presented in Section “Tests and Discussion”, which is an
Android application, called Itiner@.
Final Architecture
The fi nal architecture (see Fig. 9) combines GIS functionality with semantic
data stored in a relational database.
We developed a location-aware application that provides an all-in-
one system with the following features: 1) stores and manages spatial
data locally; 2) displays cartographic data and facilitates interaction with
