PARTICIPATORY MAPPING TO FILL DATA GAP FOR BETTER FLOOD INFORMATION

MANAGEMENT IN JAKARTA

Flood Risk Workshop & Urban Resilience 2

Background

• Have only limited access to tables, and hard copy maps

• data is not easy to manage or even search

• Inexistence of higher resolution data on : – administration boundaries

– Critical assets (important buildings)

Population : 10,000,000+

Why Participatory Mapping?

• Map is the best way to describe earth surface

• Most of the maps used for decision making often not consider local knowledge

• Knowledge of one’s environment is best described by the people who lives in the neighborhood itself

Participatory mapping - also called community-based mapping - is a general term used to define

a set of approaches and techniques that combines the tools of modern cartography with participatory methods to represent the spatial

knowledge of local communities.

Why we’re doing it?

• To help the decision making process before and after disaster with provision of more complete & accurate information

• To ensure better provision on spatial & tabular data

• Collection of information that can be used in the process of development planning, Contingency Planning, damage & loss assessment & development of priority plan in post disaster

• Community engagement

• open and accessible for further improvement

How we do it? • Participation

• Collaboration

• Technical Support

• Open sourcing

• With support from

BNPB, North Jakarta Municipality, Central Jakarta Municipality, West Jakarta Municipality, East Jakarta Municipality, South Jakarta Municipality, AIFDR (Funded by AusAID), World Bank - GFDRR, UNOCHA, University of Indonesia and Humanitarian OpenStreetMap Team (HOT)

(Technology and Local Knowledge)

Where we do it?

We’re visiting all the municipality offices and work together with the heads of villages on mapping their areas

DKI Jakarta Mapping Project

• 6 Regions (5 Municipalities + 1 Regency)

• 44 sub-district (Kecamatan)

• 267 villages (Kelurahan)

• 2,658 sub-villages (RW)

• 124 flood affected villages

Mapping Workshops • Held at each Municipality office

• Villages were provided with a package of maps and information prior to workshop

• At each workshop the Village representatives were assisted by a trained University Student

• Ask to map: Sub-village boundaries, Government buildings, Hospitals, Clinics, Schools, Place of Worship, Sport Facilities, Open Areas etc Before Flood

• Ask to map : damage/flood impacted assets of 15 subsectors After Flood

Results • 6 workshops before flood

& 5 workshops after flood

• 100% attendance 267 Villages before flood

• 95% attendace of 124 affected villages after flood

• Over 6,000 structures digitised

• 2,668 sub villages (RW) mapped

• Impacted assets of 15 subsectors identified

What is the end result (pre disaster mapping)?

Critical Infrastructure Admin Boundaries

Based on the support from Head of Village we map RW boundaries across Jakarta

What is the end result (post disaster mapping)?

What is its utility ? Before Disaster:

Can be used as base map

Can be use for further analyze on the impact of disaster

For planning purpose

Data accessible

Post Disaster :

Estimate damage & loss (amount & location, distribution )

Develop Priority Plan for Rehabilitation & Reconstruction

OpenStreetMap Support for Participatory Mapping in Indonesia

What is OpenStreetMap?

openstreetmap.org

What is OpenStreetMap?

OpenStreetMap (OSM) is an internet project devoted to creating a map of the entire world that is free for anyone to use. The map is made entirely by volunteers who use GPS, aerial imagery, and free software to add information to the worldwide map.

Why OpenStreetMap?

• Free to use (license ODbL 1.0)

• Everyone can edit

• Data quality always improved

• Supported by volunteers worldwide

• Data can be retrieved back easily (hot-exports.geofabrik.de or download.geofabrik.de)

• Lot of tools

OpenStreetMap Support for Participatory Mapping in Jakarta

• Supporting the initial training for university student before they work as mapping assistance

• Supporting on the main mapping event by providing handouts, tips, and mapping guides (all materials can be found on learnosm.org)

• Direct support for software/tools troubleshoots

• Assisting editor and validation team to help improve the data quality

THE ROLE OF UNIVERSITY

Why University?

University has three main objectives

• Education

• Research

• Community Service

UI’s Role in The Project

• 72 Students with basic GIS skill, good communication and interpersonal skills

• Provide their assistance to compile and to digitize data from each Kelurahan

• Provide mapping assistance through OpenStreetMap & other software

• Actively communicate with the Head of Kelurahan to fill-out out the provided template of information

What’s Next?

Making villages (kelurahan) office as agent to maintain & update data

Expanding the initiative to be included into other hazard analyses (from mainly only flood)

Encourage risk data to be considered in sector planning e.g.settlement affected most
