A Cadastral Survey System of Mountain Forest Area using Remote Sensing Technologies

Abstract

A cadastral survey system for mountain forest area using aerial and space remote sensing technologies has been established for solving a difficulty to make onsite parcel boundary demarcation by aged land owners. In the system, the parcel boundaries are interpreted and measured by cadastral surveyors utilizing remote sensing information as well as existing old parcel maps as basic reference data, after making limited amount of field survey with local authority, in order to make tentative parcel maps. Then, the tentative parcel maps are confirmed by land owners at a community center. If the tentative parcel boundaries are approved by the land owners, the boundary data are treated as official cadaster data. In case some tentative boundary data are not approved and onsite demarcations are requested, the data are corrected by field survey. In this paper, an overview of the system is given.
