Damaged buildings are identified by changes to their shadows between pre- and post-event data. The approach makes use of object-based image analysis concepts to extract relevant information on damage distribution. The methodology selected requires pre-and post-disaster images with similar sun angles and will only be suitable for the detection of collapsed (or partly collapsed) structures. The new methodology proved to be effective for the Carrefour area despite using satellite images of different qualities with inadequate image (co-)registration, producing positively validated results within an acceptable processing time, and was, to the best of our knowledge, the only automated damage assessment method to have delivered appropriate results to requesting relief organizations within a few days of the Haiti earthquake.

Analytical 3D views and virtual globes: scientific results in a familiar spatial context / D. Tiede in ISPRS Journal of photogrammetry and remote sensing, vol 65 n° 3 (May - June 2010)

Four case studies are presented, in which information extraction results from very high spatial resolution (VHSR) satellite images were conditioned and aggregated or disaggregated to regular spatial units. The case studies were embedded in the context of: (1) urban life quality assessment (Salzburg/Austria); (2) post-disaster assessment (Harare/Zimbabwe); (3) emergency response (Lukole/Tanzania); and (4) contingency planning (faked crisis scenario/Germany). The results are made available in different virtual globe environments, using the implemented contextual data (such as satellite imagery, aerial photographs, and auxiliary geodata) as valuable additional context information. Both day-to-day users and high-level decision makers are addressees of this tailored information product. The degree of abstraction required for understanding a complex analytical content is balanced with the ease and appeal by which the context is conveyed.

Earth observation in conflict mitigation / Olaf Kranz in GIM international, vol 23 n° 7 (July 2009)

Millions of civilians have had to leave their homes and hundreds of thousands have died as a result to attacks. The worst years of fighting were 2003 and 2004, but violence is on the increase again. International peacekeeping has not proved effective and access to humanitarian agencies is limited. A powerful tool in support of planning process for international missions is earth observation (EO) via up-to-date satellite imagery.

Combined object-based classification and manual interpretation-synergies for a quantitative assessment of parcels and biotopes / S. Lang in Geocarto international, vol 24 n° 2 (April - May 2009)

At the interface of GIS and remote sensing, object-based image analysis methodologies are one possible approach to close this gap. With this, methods from either side are integrated to use both the capabilities of information extraction from image data and the power to perform spatial analysis on derived polygon data. However, dealing with image objects from various sources and in different scales implies combining data with inconsistent boundaries. A landscape interpretation support tool (LIST) is introduced which seeks to investigate and quantify spatial relationships among image objects stemming from different sources by using the concept of spatial coincidence. Moreover, considering different categories of object fate, LIST enables a change categorization for each polygon of a time series of classifications. The application of LIST is illustrated by two case-studies, using Landsat TM and ETM as well as CIR aerial photographs: the first showing how the tool is used to perform object quantification and change analysis; the latter demonstrating how superior aggregation capabilities of the human brain can be combined with the fine spatial segmentation and classification. Possible fields of application are identified and limitations of the approach are discussed.
