State of the Map Asia (SotM-Asia) is the annual regional conference of OpenStreetMap (OSM) organized by OSM communities in Asia. First SotM-Asia was organized in Jakarta, Indonesia in 2015, and the second was organized in Manila, Philippines in 2016. This year’s conference, third in the series, was organized in Kathmandu, Nepal on September 23 – 24, 2017 at Park Village Resort, Budhanilkantha, Kathmandu, Nepal. We brought nearly 200 Open Mapping enthusiasts from Asia and beyond to this year’s SotM-Asia. The event provided an opportunity to share knowledge and experience among mappers; expand their network; and generate ideas to expand map coverage and effective use of OSM data in Asian continent. We chose ‘from creation to use of OSM data’ as the theme of this year’s conference, emphasizing on the effective use of OSM data. We also brought together a government panel from four different countries in this year’s SotM-Asia. We believe this event will deepen the bond and enhance collaboration among OSM communities across Asia. More information about the conference can be found on: http://stateofthemap.asia.

2. Building back better!
Longer-term goal:

3. Immediate need:
Damage survey of 1 million houses

4. Traditionally…
▶ Thousands of surveyors
▶ Stacks of paper questionnaire
▶ Conduct survey for months
▶ Bring back heaps of filled up forms
▶ Spend another few months transcribing the data
▶ And then only start analyzing data to formulate
intervention plans

5. How a 7.8 Mg earthquake started
a digital revolution in Nepal

6. This time, we used electronic tablets:
▶ Better data quality
▶ Zero transcription time
▶ Zero transcription cost
▶ Shorter turnaround period
▶ Enhanced data security
▶ Richer dataset (GPS, pictures of a million houses)
▶ Near real-time data

7. 76% of the total data to be surveyed
were collected and usable within the
first 100 days of the survey

8. Challenge: Non-tech
▶ Momentous shift from paper to digital survey
▶ Hiring, deploying 2,500 survey teams
▶ Keeping all stakeholders on the same page
▶ Procuring and managing survey logisitics

9. Challenge: Tech
▶ Totally offline
▶ Compress photos (from 5 MB to 0.4 MB)
▶ Upload photos separately from text data
▶ Battery life
▶ (Near) real-time?
