摘要:The use of HR and VHR (high/very high spatial resolution) imagery and OBIA (objectbasedimage analysis) offers new possibilities for monitoring activities in and aroundrefugee camps to manage, understand, and assess developments and impacts of the camp onits environment (see for example TIEDE et al. 2013, HAGENLOCHER et al. 2012). Here wedemonstrate how VHR imagery in combination with OBIA can be used to retrieve andcreate valuable information about a remote refugee camp and its surroundings before,during, and after the dismantling and the repatriation process. Feature extraction approachesfor single dwellings and further information retrieval, as well as land cover classificationfor the refugee camp Lukole in Tanzania were combined for an integrated monitoringapproach.
