Abstract
As the newest nation of the 21st Century, (East-Timor) faces the challenges of conducting her first population census after independence. This paper reviews the current mapping situation in East-Timor and presents how advanced mobile mapping techniques were used to delineate census enumeration areas in Dili metropolis. The peculiar nature of Dili, where the issue of building ownership and property boundaries remained contentious, coupled with the non-availability of up-to-date cadastral maps; led to a combination of remote sensing and geographical information system techniques being used to map census enumeration areas. QUICKBIRD high-resolution satellite imagery, GPS and an Internet enabled palm-top computer running on windows mobile operating system together with ArcPad 6.0.2 software were used to delineate census enumeration area maps. The methodological steps undertaken for the mobile mapping technique are narrated in this paper and the outcomes of the pilot study are compared with the traditional census enumeration area delineation methods.
