Discussione su OpenStreetMap, sistemi GIS classici, confronti, potenzialità di OSM e dei suoi strumenti di estrazione dati. Slide per la conferenza OpenGeoData Italia - Roma - 27 febbraio 2014.

1. OSM for
developers
or, how I stopped worrying about layers,
and love the database
Simone Cortesi @simonecortesi
Maurizio Napolitano @napo

5. Understanding the data
there is no layer(s)
Tagging
Map Features, Taginfo

6. Existing Solutions
Linux, Virtual Machines
Osm2postgresql
OpenCageData
Geofabrik, Osm2Shp
Osm2pgsql, Osmosis

7. Solution

8. OSM “planet” files
Requesting large amounts of data from API can place undue load on
the OSM server
API is really designed for adding and editing data, not retrieving
So OSM also makes its data available as downloadable “planet” files in
OSM XML format, containing OSM data for the entire planet
Whole planet too large for most to use directly, so country or regional
extracts available (eg. Geofabrik)

9. OSM planet is huge
The complete OSM Data
Latest Weekly Planet File: 33 GB
Latest Weekly Changesets: 782 MB

10. Rendering the map on your PC with
Tilemill

11. Tilemill
Pavia
showing building age
colorcoding based on native OSM data
satdt=
tr_ae*
2 hour job
tilemill is free and opensource software

12. web visualization
Openlayers
Leaflet.JS
Modestmaps
d3.js
mapstraction

13. Leaflet.JS

20. Editing the data
JOSM
Standalone editor, written in Java
Powerful and flexible
Communicates with API over HTTP
Potlatch
Online Flash Editor
Easy to use
iD
HTML5/JavaScript/d3.js, in early development

25. Services
geocoding - routing - public transport - quality assurance

26. Geocoding
Search engine services
Nominatim (official with fair use policy ) by Mapquest (data under
ODbL)
Cloudmade - with API commercial support (15$ per 100,000
transactions)
GISGraphy - with API commercial support
Search engine open source software
Nominatim php+postgresql
GISGraphy (LGPL) java+postgresql offers API for Android like Google
Photon (Apache License 2.0) java+postgresql+solr used in komoot

29. Routing
There are many offline, embedded and web-based routing services
using OpenStreetMap data
Please visit: http://wiki.openstreetmap.org/wiki/Routing
pg_routing: extension for postgis with osm data support GPL,C++
OSRM C++,BSD, research oriented
Grasshoper Java, Apache, Scales from big server to mobile device,
works on Raspberry Pi
OSRM C++,BSD, research oriented
Spatialite VirtualNetwork C, GPL/LGPL/MPL, portable
... and other services in the cloud made available by Cloudmade,
MapQuest, Skobbler...

30. Public Transport
OpenTripPlanner provides a range of passenger information and
transportation network analysis features using our infrastructure for
finding itineraries combining transit, pedestrian, bike, and car segments.
network from osm, tpl from gtfs sources, lgpl, java

31. quality assurance
... again a lot of tools
http://wiki.openstreetmap.org/wiki/Quality_Assurance
We suggest to look and collaborate with OSMOSE
