6. Suggests in Next!
Next! “automatically” know what is the
nearest place closest to user interests
Using Search Graph, Next! traces all
sites visited by users
In this way, is easy to suggest the right
next sites for an user

10. Requirements Specification
Georeferenced map
according to user location
Path building that connects
the user to a cultural site
Map should include other
info like parking, foods,
leisure...
giovedì 6 giugno 13

11. Data Analysis
Overlay maps with
cultural sites and
other places
A Base map

12. DATA/SERVICE REQUESTED HW/SW NEEDED
Base Map Map Server
Overlay Map Map Server
Path building External Application
Hw/Sw Analysis

13. Choosing Hw/Sw
CloudMade provides tile
maps to Next! Navigator
Its license is narrow-free
For this reason, we
expected also the maps
provided by MQ
giovedì 6 giugno 13

14. OSM allows free access to
maps and all data you need
The overlay maps are
created by ourself, using
QuantumGIS

20. What’s in GeoDB
In the geoDB there are data obtained from
different sources
Data for Overlay Maps
Data for Routing construction
giovedì 6 giugno 13

21. Insert Data in GeoDB
Data used for the overlay maps
inserted in the GeoDB using Spit, a
QGIS plugin
Data used for the routing construction inserted in
the GeoDB using osm2po
SPIT

22. pgrouting allows to choose between
1) Dijkstra Shortest path
2) A-Star Shortest path
3) Shooting-Star Shortest path
Path Building
pgrouting is an open source library that provides
geospacial routing functionality
pgrouting gets the user position
by GPS and cultural site position
by Nominatim geocoder

Leaflet is a JavaScript library that
allows the construction of
interactive maps
Leaflet allows the user to control
the map (zoom, classic view, night
view, satellite view)
