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)

• Cost-Effective possible doing voluntary
• Operate by Local Staff possible participatory
• Sharp and enough accuracy to see individual
• Fast in Production

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..
