Creating a better, accessible and efficient online map of Kathmandu Valley
adyota.org
What is "MapKathmandu?"
● Initiative to make a detailed online map of Kathmandu Valley
● Make the map free to use● Use crowdsourcing to speed up data upload● Create a community of active mappers
Who are we?
● Group of graduate students and young professionals who want to see change in Nepal
● 3 based in the U.S., 2 in Europe and 1 in Nepal
● Diverse background from mapping and engineering to journalism and management
Why map Kathmandu?
● Disaster relief and medical emergency● Easy navigation● Enable businesses to deliver services and
products easily● Enable innovation in location based mobile
apps and services
How does the current map of Kathmandu look like?
Zooming into Baneshwor
Saw the problems?
● Many streets are not traced yet● Names of most of the streets are missing● Many other items of interest are missing● Not very usable, same with Google maps
Is there a solution? YES!
● Low budget, no politics● Crowd effort● Community of active OSM contributors● Youth who want to make a difference
Why is it the right time?
● Active and growing OSM Nepal community● Support from universities and media● Earthquake awareness● Smartphone revolution, faster internet● Youths want to solve problems themselves
Opportunity to build a critical mass of active contributors
How we can help?
● Map the city with the help of interns and volunteers at Adyota
● Provide training on OSM● Form a community of active mappers● Support with funding● Run projects with universities and other
youth groups to make direct impact○ Part of the curriculum/course○ Competition based projects○ Extracurricular credits
What we will map?● Roads:
○ All roads that are accessible by car and bus-stops○ GPS traces of narrower roads and their names when possible
● Buildings and landmarks:○ Hospitals, clinics, blood banks, pharmacies○ Schools, Government offices, Ward offices○ Banks, large businesses, ATMs, tourist landmarks
○ Bridges, temples, chowks, bahal○ Public toilets, garbage containers, major public open spaces,
named intersections, roundabouts

Why?
(sub-question: why not google maps?)
For us:
Same as why
(maps, like encyclopedia articles, are awesome information, lets have a free world-editable version!)
Mapping data is not free
Mistakes cannot be corrected
(these are first-world examples;
Nepal has its own set of
delicious ones)
Off-line possibilities
Apps! (both use and write...)
OpenStreetMap is Volunteered Geographic Information: the harnessing of tools to create, assemble, and disseminate geographic data provided voluntarily by individuals.Goodchild, M.F. (2007). "Citizens as sensors: the world of volunteered geography". GeoJournal 69 (4): 211–221
Open DataThe one GIS data platform to rule them all (?)
UN
ICIMOD
SURVEY Dept.
VDC
खानेपानी सं था
सडक बभाग
Who else?
Re-use & reprint (legally)
What?(ie, what exactly are we talking about?)
- nodes- ways- tags- relations (only advanced)
How?
(how to add data to OSM?)
GPS tracks
Imagery!
Local Knowledge
Data sources
UNNepal govt.?
ICIMOD
Who else?
(Challenge: Licensing)
OpenStreetMap editing tools
Potlatch – Flash-based web editor
OpenStreetMap editing tools
JOSM – Java-based desktop editor
We can do it!
Case Study: Haiti
Possibilities?Haiti before the earthquake
Haiti within 24 hrs of the earthquake
Haiti in the following days
