This peninsula constitutes the prototype project area for the main IGM-INACH project No 153 “Cartographic Survey and Geographic Information System of the South Shetlands Islands” The Digital Cartography was implemented at the 1:5 000 scale, using geodetic GPS control points referenced to ITRF 92 and WGS 84 Data. The UTM Projection was used. All products were produced in compliance with the cartographic standards of the IGM. This cartography was designed in order to satisfy the requirements of a Geographic Information System developed by INACH. This geo-referenced database incorporates a variety of thematic information, enabling it to support scientific investigations, environmental and multi-disciplinary studies, and other applications. As a result of this project the Instituto Geográfico Militar de Chile produced a map at 1:5 000 scale in digital format, and also a 1:10 000 topographic map, in paper format, with two editions: first edition of two charts and a second edition with one chart covering the whole project area. Chile and other countries have a number of important permanent activities in this area. These maps are designed to support several and diverse geo-spatial studies related to these activities.展开更多

The paper evidences that there are three important aspects about parcels： relational database, survey of geometry and land registry. Inserting irregular settlements inside an urban development pattern is the duty of local authorities that apply the Territorial Order Plan to the slums located in the city of Belo Horizonte, Brazil The Territorial Order is developed by the City Hall via the District Planning Secretariat, and it is approved or revised by the district itself. It concerns public areas and urban planning. The paper also presents some research results related to the cadastral aspects of spatial use above and below surface--the 3D cadaster. The main objective of such research is to set the outlines of the development of a spatial cadastral model for irregular settlements. Finally, the paper defines the guidelines for the transition from surface cadaster into spatial eadaster.展开更多
