This document provides information about a mapping party organized by the Free Software Movement Karnataka to map areas using OpenStreetMap. It introduces OpenStreetMap and explains how to get started with mapping using a GPS-enabled smartphone and OSMTracker app. Details are given on registering an OSM account, using editing tools like iD and JOSM, OSM data structure of nodes, ways and tags, and how to upload tracked GPS data to OSM to start mapping.

4. AN INTRODUCTION TO OPENSTREETMAP
What's OpenStreetMap(OSM)?
AWikipedia-style platform for maps – open, transparentand
editable byanyone with adesire to do so.
Started in 2004, its builtbyacommunityof mappers that
contribute and maintain free geographic dataof the entire planet
through collaboration.

5. WHY OPENSTREETMAP?
(WhenwehaveGoogle,HERE,Bing,andothers!)
PresentMaps/Geodataisn't
Free (as in Freedom)
Open
Emphasize localknowledge
Wikiis obvious nextstep
Its justfun

6. WHY DO WE NEED FREE GEODATA?
Free Geodataallows generatingfree AND cusotmized maps.

14. INTRODUCTION TO MAPPING
Whatdo we need?
How do we do?
How the OSM datais structured -Geometryand Tags.
And there are three ways of editingOSM -
1. Usingaerialimagery
2. UsingGPS data(*.gpx) from trackingapps through ground
survey
3. Importingexistinggeodatawhich is compatible with
ODBl(Open Database License) to OSM.

15. WHAT DO WE NEED?
GPS enabled smartphone with trackingapp for ground survey.
Osm registered account.
Tools to convertexistinggeodataif importingis to be done.

16. HOW DO WE DO?
Register and verifyaaccountin osm.
Use anyof these popular GUI editors are:
1. iD -web-based HTML5 editor(easyone)
2. JOSM -Javabased desktop editor(advanced editor)
3. Poltach -Flash-based web editor(notcommonlyused now)
Upload the datato OSM.

17. OSM DATA STRUCTURE
1. Geometry--
Node(Point): Used for mappingPoints of Interest(POIs). Ex:
Cafe's, Shop, etc.,.
Ways: Used for mappingRoads, Rivers, etc.,.
Area: Used for mappingRegionalboundaries, Buildings,
Forests, etc.,.
2. Tags --
Representhow datais saved in OSM.
Theyare atype of key-value pair
Ex: amenity:cafe, name:Coffee day, landuse:forest, etc.,.

18. MAPPING USING OSMTRACKER GPS DATA
InstallOSMTracker app(Available on
Fdroid) to your GPS-enabled smartphone
and turn on GPS
Starttrackingbytakingnote or pic or voice
rec.
Once the trackingis done, save itand export
the track to gpx format
Copythe gpx file to the machine or upload
directlyto osm for editing.

19. Upload into your osm profile from the app

20. STARTING EDITING
1. Go to
2. Sign up and confirm email.
3. Sign in to
4. Open the uploaded track and zoom to your area
5. Click on Editto startediting.
