RAPID ASSESSMENT OF ENVIRONMENTAL CHANGES
IN POST DISASTER AREAS UTILIZINGUAV-BASED MAPPING
1. Before Disaster (mitigation, simulation, earlywarning)
2. When Disaster (rapid assessment, emergencyresponse)
3. Post-Disaster (monitoring, rehabilitation)

Why UAV-Based ? RIMSRapid Imaging and Mapping SystemTeknologi Karya Kreatif Anak Bangsa
Person In Charge
Di Lapangan
UAV
Tele-kontrol maks
10km
Autopilot
Berat < 2.5kg
Kemampuan produksi
< 750Ha per Hari
Cost-Effective possible doing voluntary
Operate by Local Staff possible participatory
Sharp and enough accuracy to see individual
Fast in Production

Indonesia Region (Land Part)
+ 190 Million Ha
so big so many Island so beautiful also
-
Meeting the Need for disaster mapping:
- In General, Damage Area < 3000 Ha
(EXCEPT ACEH/EARTHQUAKE)
- High Accuracy up to 0.1m resolution and geometric quality
(TO SEE THE OBJECTS....)
- Low cost, fast in production, and easy in operate
(DEPLOYABLE, PORTABLE, RESPONDABLE, SAFETY)
Indonesia Region (Land Part)
BUT high risk form disaster

Some Facts, regarding the needs for imagery
Most of People want to see the objects
Satellite Imagery is not enough to see the objects
The Damages Happen in small area (< 3500Ha)
Its lucky, if we have up to date geo-database
limited cost; operator/technicians; any fast product?
Running UAV-based Photogrammetry can handle those facts and have some benefits also

Seeing the Parameter for a Better Anticipation
Tsunami, its parameters: the strength of the quake, coastal bathymetry, coastal land use, historical records
Landslide, parameters: rainfall, soil slope, soil structure, land use, the historical record.
Volcano (eruption and debris flow), its parameters: topography, watersheds, land use, changes in dimensions, gas / chemical, a record period of eruption.
Earthquake (tectonic), parameter: the movement of the plates, layer structure, the condition of buildings, land use, historical records
-
Flood, parameters: rainfall, tides, soil porosity, land use, elevation, surface hydrological network, the historical record.
Fire, parameters: surface temperature (hot-spot), density, network utilities, water resources.
Tropical Cyclon, parameters: meteorology, land use, utility network
Drought, parameters: Climate change, land use, surface hydrology
Epidemic of disease, social conflict, failure of technology, population density, economic-region
Seeing the Parameter for a Better Anticipation
-
Demanding The Common Data
Terrain topography: elevation, slope, watersheds, geomorphology, etc.
Cover and land use patterns
The existence of assets: infrastructure, Public Facilities, utility networks, property rights, etc.
Population density / residential
Meteorology, climatology
bathymetry, oceanography, current patterns, etc.
Can UAV-imagery see all of those ?

Only Damage Houses can be seen
-
Imagery from the system with spatial resolution less than 20cm can
see man-made objects and the enviromental changes clearly.
The existence of previous data (existing) is very important in terms of
assessing the changes that occur. Not all objects can be seen from
the air as a result most of the objects covered by the higher object.
The Houses with minor damaged (cracked) can not be interpreted
clearly on the aerial photo image.
In the future, need to be developed in terms of process automation
objects valuation changes (change detection) to speed up the
process of assessment in environmental.
This technique also open the possibilities for running the participatory
mapping, where local people can be involve in thematic map
production..
