Abstract


Merapi eruption in 2010 causing major damage impact on that region. Post-disaster damage assessment that
has been done by the government have not been supported with a good spatial data so that validation is
relatively weak. Method of post-disaster damage assessment, particularly assessment of building damage using
geotagged photos, remote sensing and GIS is expected to improve the method of damage assessment by the
government of Indonesia. Geojot Applications for Android Smartphone/Tablet allows the assessment of building
damage to be included in the photo attribute. Interpretation of satellite imagery of building damage is done by
using three indications: building visibility, building collapse, and building roof. Geotagged photograph can
complement the needs of building damage assessment from satellite images because it can describe the
structural and non-structural damage to buildings clearly. Geotagged photograph with GPS Lock-Off mode
requiring information on the direction and distance of the object being photographed. Geotagged photograph
with the QR code is the most profitable because the identity of the building is already known and can be
matched with an existing database.
