The document outlines a townwatching manual that uses community observation and ICT to develop community-based hazard maps. It involves 4 phases: 1) developing an OSM basemap with community mapping; 2) community hazard mapping of risks, buildings and evacuation routes using a mobile app; 3) a demonstration drill and crisis mapping; and 4) policy discussions to improve community resilience. The goal is to strengthen disaster resilience by applying space-based technology and ICT to involve communities in developing hazard maps and sharing reliable disaster data.

2. Installation/Registration of geoBingAn
• Download from playstore
• Register with email address and a password of your
choosing
• Check your email for approval
• Follow email instructions

3. Membership of geoBingAn for
townwatching
• Download from playstore
• Register with email address and a password of your
choosing
• Check your email for approval
• Follow email instructions

4. Prepare Materials
• In geoBingAn.info use the OSM
basemap to create a paper
map of the area extent of your
townwatching activity
• The paper map should
highlight the following:
all public buildings such as:
schools, shelters, hospitals,
police and fire stations
All OSM buildings
All roads, paths, waterways and
open space

5. Still waiting for the create/print map
function for manual input
• Visualizing
OSM data
(public
buildings)
• Creating a
map

6. Creating Groups
• Groups should be composed of a
heterogeneous mix of stakeholders and not
exceed more than 7 people;
• Each group should have one disaster
management expert

7. Still waiting for the administrator
function so members can have tw
function on their mobile phone

8. What is townwatching?
Townwatching is a process to prepare a community-
based hazard map for disaster reduction through
community-based observation. A hazard map
provides graphic information on potential natural
hazards and evacuation matters.
Community based hazard mapping has 3 key objectives:
a) involve local residents in developing the hazard map for their community
b) reflect the opinions of local residents in policies made by their local government,
and
c) foster common understanding of risks among local residents, government officials
and experts

9. Collecting Data in the
Field
Once in the field each group will
walk around their community
and record information that will
either be advantageous or
disadvantageous during a
disaster. This information is
recorded using geoBingAn
mobile application. Groups
should focus on Evacuation and
shelters information and
previous disasters in their
community. A simple list of
presets available on GeoBingAn
mobile application to capture
this information is below.
Evacuation
Road Condition (Good, Poor, Dangerous)
Stair condition on road slope (Good, Poor)
# Sudden depression in the road (Y/N)
Possible road barriers (Slope, Sudden Depression, Unstable Structures, Narrow Brid
Poor quality bridge, could be damaged by earthquakes
Street light (Yes/No)
Dangerous electric poles/wiring on the road (Y/N)
Available open space (Closed, Open)
Shelter
Shelter is more than one storey (Y/N)
Shelter is strong enough for earthquakes (Y/N)
Shelter is strong enough for cyclones (Y/N)
Shelter capacity ________________
Shelter has adequate water supplies (Y/N)
Shelter has sufficient toilets (Y/N)
Flood
The area/building was flooded before (Y/N)
Flood type (Riverine, Flash, Embankment breach, local rainfall)
Presence of flood early warning system (Y/N)
Availability of public information board for flood (Y/N)
Maximum level during recent floods (Knee, Waist, Chest, above Head)
Cyclone
The area/building was affected by cyclone before (Y/N)
The area/building was inundated by storm surge before (Y/N)
The area is open (Y/N)
The area is on a higher elevation (Y/N)
The area has a concentration of light material/poor quality buildings (Y/N)
Availability of public board for cyclone (Y/N)
Earthquake
Building is strong enough for earthquakes (Y/N)
The area/building was inundated by storm surge before (Y/N)
The area is open (Y/N)
Landslide
The area/building is located in or near slope more than 30 Degree (Y/N)
Slope is covered by vegetation (Y/N)
Presence of landslide mitigation measures (Y/N)
Availability of public information board for landslide (Y/N)

10. Advantageous or Disadvantageous
Advantageous/Capacities
 things that will increase
community’s resilience to
disaster
 signage informing the
public about disaster or
hazards in the area
 weather station
 shelter
Disadvantageous/Vulnerabilities
 previous disaster has
occurred
 high water marks or the
extent of a storm surge
 poor quality
infrastructure
 areas likely to be
affected by future
hazards

11. Shelter
• Draw small polygons around shelters

12. Evacuation route
• Evacuation route criteria:
Routes should avoid hazard polygons
Evacuation routes should start at an highly
dense area and link people to shelters

14. Why?
• Disaster events are increasing
in Asia
• Technology and information is
becoming available at zero to
low cost which can help people
access and create information
helpful in disaster risk
management

15. How?

16. Organizations Involved
• To be developed

17. 1)Community-based
OSM base map
development;
2)Community-based
mapping of
hazards, risks,
buildings and
evacuation routes;
3)Crisis mapping;
4)Utilization of
satellite-based
damage
assessment;
5)Data management
using GIS at local
governments; and
6)Utilization of data at
the community level
for DRR, response

18. Phase 1: Community-based OSM base map development
Roles and Responsibilities
Nation consultants – organize
mapathons and teach communities
members how to use OSM and a
mobile application to map their
community

imagery is not clear enough for
mapping
AIT – work with ADRC to develop
the list of attributes to be field
validated, train NC’s in using the
mobile application for field
validation

application to field validate OSM
data

19. Phase 1: Community-based OSM base map development
Output - OSM basemap
Uses of OSM basemap
Community hazard mapping– OSM basemap will be
used in Phase 2 townwatching to create a community hazard map
Building damage assessment – following a disaster,
community can use a mobile application to perform a building damage
assessment – in SW3 statistics can be generated to inform the
government of economic loss in the area

21. Status of OSM desktop mapping in
pilot area

22. Once OSM buildings and roads data was available attribute information was added to
the data through community field validation using mobile application geoMapTool –
information collect on this mobile application is then uploaded directly to OSM
Platform
