1. Open Street Map (OSM)
It’s Linux to Windows
It’s about claiming our own world and space

2. Introduction
 OpenStreetMap (OSM) was founded in July 2004
by Steve Coast
 In April 2006, the OpenStreetMap Foundation (OSMF)
was established to encourage the growth, development
and distribution of free geospatial data and provide
geospatial data for anybody to use and share.
 In March 2008, founders announced that they have
received venture capital funding of 2.4 million euros
for CloudMade, a commercial company that will use
OpenStreetMap data
 In Nov 2011, OpenStreetMap is having 500,000
registered users

4. Methodology
 Download the data from
http://planet.openstreetmap.org/
 Check the authenticity of the data
 Edit the map
 Edit the data
 Download the latest available map to check if any
changes has been made to the map
 Upload the map

5. Data Collection
Data can be collected by the following methods:
 GPS- This is currently the most common way of
gathering data for OSM, and often preferred or
even essential for collecting the initial geometry
of roads, paths and other ways.
 Local knowledge - Perhaps the best source of
data, though, is if one simply happen to know the
area very well, and thus for example the names
of the roads, which shops or buildings there are,
the local traffic rules and restrictions, or what
ever else one might want to add to OSM.
 Seeing mistakes in a map and fixing them.

6. What data to add
There are lot of data that can be gathered and put
into OSM:
 Parks and playgrounds
 Shopping malls and supermarket
 Accomodation
 Transport areas
 Water-bodies, Lakes and drains
 Power Supply
 Barriers
 Man-made structures.

7. Editing the Map
The map can be edited in the following two
ways:
 Front End: Using the inbuilt software Potlatch
in the openstreetmap website
 Back End: Map editing can be done using
JOSM editor and upload the edited map in the
OSM website

8. Editing in the website
 Create a user id login
 Click on Edit map to enable editing
 Type the name of place in search tab to get the
map
 Use potlatch to edit the map
 Once editing is done save the data
 Changes will be reflected in the map

10. Creating maps using OSM
1. Install JOSM
First we need to go to the JOSM download site (
http://josm.openstreetmap.de/) and get the latest
version. At the bottom of the page we'll find the
'download' link. Save the 'josm-latest.jar' file on
your desktop.
If everything is okay, one should have the JOSM
editor application now running and the page
looks like:

12. Map Downloading
2. Download a MAP
To do this go to the OpenStreemMap website (
http://www.openstreetmap.org/). Search for
your favorite city e.g. 'Copenhagen'. Click first
on a search result and then on the 'view' tab on
the top of the webpage. One need to click 'view'
to see the exact URL or HTTP address in you
browser location bar.
Now, copy this URL with ctrl-c and go to your
JOSM application. Open 'File->Download from
OSM...':

14. And paste with ctrl-v the URL in the textarea on
the bottom:

15. Data Composition
OSM's data is made up from the following elements:
 Nodes: The dots that are used to mark specific locations
(such as a post box) or for drawing segments between.
 Ways: An ordered list of nodes, displayed as connected
by line segments. They are used to describe roads, paths
etc.
 Closed Ways: Closed ways are ways which go in a
complete loop. They are used to describe areas like parks,
lakes, islands or buildings.
 Relations: When different ways are linked to each other,
but do not represent the same physical thing, a relation is
used to describe the role of each way. They are used to
describe things like cycling routes, turn restrictions and
areas with holes.

16. The end result of should be a window containing a
vectorial view of your map:

17. Map Rendering
3. Render a MAP
 To transform the vectorial view of the map into
something more artistic is called rendering. We
need to process the sample.osm file with some
tools (eg:osmarender) and calculate all colors,
images, streets, waterways we need to put on the
map. One need to download two files and save
them into the 'openstreetmap' directory:
 osm-map-features-z17.xml
 osmarender.xsl
The first file is a features file which tells the
osmarender what you want to put on the map. The
second file is a stylesheet that directs the actual
rendering work

18. Uploading the Map

19. Uses/Advantages
 OpenStreetMap can use available satellite
imagery to map the roads, buildings and refugee
camps during crisis conditions like earthquake,
floods or other natural disasters.
 The resulting data and maps can be used by
several organizations providing relief aid, such as
Red Cross, etc
 It is compatible with Ushahidi mobile platform (a
non-profit tech company that develops free and
open source software for information collection,
visualization and interactive mapping).

20. Business Value
 We can form association with different mobile service
provider which will use this data to display maps on
mobile phones and other GPS supporting devices.
 The data will also be of use to different Driving Teaching
agencies which uses street information to teach driving.
 The data of the street maps can be sold to different game
developing vendors which use street information in their
high end games.
 We can also use the data to make segmentation for doing
market survey of some particular products.
 The data can also be used by financial intermediaries like
bank etc to prepare a loan portfolio of a particular region
or to prepare credit default rating of a region.

21. Demonstrating Business Value
 We have downloaded data about individuals from
social networking sites like LinkedIn, Jigsaw,
Spoke, etc using LeadGrabber Pro software
 The addresses of the software professionals can be
used to make a route map in OSM.
