Geoinformation for Disaster and Risk Management - ISPRS

Delays, due to security clearance and permission to
fly, meant the flight campaign was only completed in
July 2005. All final products were completed and
delivered to Bakosurtanal in April 2006. With the
exception of the DTM, Bakosurtanal provided all
products in August 2006 to the Spatial Information &
Mapping Centre, (SIM-Centre) of the GoI Agency for
Rehabilitation and Reconstruction of NAD and NIAS
(BRR), for distribution to the aid and recovery
community (users).
The data set was distributed in three ways, either;
(case 1) directly as an electronic data set to users;
(case 2) provided as a customised product; or (case
3) enabled for users electronically via web
applications. Primary data users (case 1) were given
digital (soft) copies of the data set and were bound
by a signed data user agreement. During the period
August 2006 to July 2008 there was a total of 99
recorded primary data users and over 635
secondary data users (cases 2 and 3). The data set
was also used as a core data in Geographic
Information System (GIS) training provided to at
least 500 local government officials.
Example case studies on data use
To justify their requirement for the use of the data
set, all primary data users were obliged to provide
project details, which were confirmed with an
independent project registration maintained within
the Recovery Aceh Nias Database (RAND) of the BRR.
The requests for the data set, as is shown in Figure
2a, covered the spectrum of all agencies within the
recovery and rehabilitation community. Examples of
data usage are presented in the following section.
Asian Development Bank (ADB)
The Earthquake and Tsunami Emergency Support
Project (ETESP) of the ADB used the data set in four
of their projects. The data was used to support their
Spatial Planning and Environmental Management
project, Agriculture Sector, Fisheries Sector and Road
and Bridges project. Specifically the projects
oversaw the preparation of sub-district level Action
Plans; the rehabilitation and reconstruction of
livelihoods assets post Tsunami in both agriculture
and fisheries sectors; support to fisheries
rehabilitation in Aceh and Nias and the creation of
the design and project preparation documents for
road segments within Banda Aceh and on the East
coast. The four projects had over 125,000 direct
beneficiaries and cost a total of over 79 Million Euro.
The data set was used to some extent, in all five
phases of each project's lifecycle (i.e. project
initiation, planning, operation, monitoring and
evaluation and project closure), but was most
significantly used in the operational phase of the
projects. Over 85 maps were created within the
projects from the case study data set and GIS data
sets provided.
United Nations Development Programme
(UNDP)
The UNDP through its Tsunami Recovery Waste
Management Programme (TRWMP) began the
program for Agriculture land clearances in January
2006.It removed the heavy deposits of sand, silt and
debris blanketing the land, and blocking the
irrigation channels and drains. The program cost
over 1.5 million Euro and supported 2600 families as
direct beneficiaries. The TRWMP used numerous
spatial data sets, including the orthophoto data set,
to locate areas in greatest need of land clearance,
and to work with farmers and community leaders to
demark field boundaries, canals and drains.
The orthophoto data set was used as a primary
mapping tool to determine areas and potential
volumes of waste that required removal and to
prepare clearance plans. This information was
critical for preparation of heavy equipment contracts
required for land clearance. The data set was
critically used for project planning, operation and
monitoring and evaluation and is estimated that it
would cost approximately 200,000 Euro to obtain
the same information from different sources.
Data user survey
To asses the benefit of the orthophoto data, a data
user survey was undertaken in Aceh, during 2008.
The survey, delivered as a questionnaire, was
distributed to all primary data users. To encourage a
high response rate, the survey was intentionally
simple and brief. It was designed to retrieve
information to determine answers to the following
study questions:
�Which category of organisation were the
main users of the data set?
�What type of project required the data set
and how was it used?
�At which phase of the project life cycle was
the data set most significant?
�What was the benefit of using the data set?
�What were the problems with the data set?
