Abstract
Chile Political Boundaries is a line theme representing political boundaries in Chile. This layer is a component of the Global Map, a 1:1,000,000 scale framework dataset of the world. It consists of vector and raster layers of transport, administrative boundaries, drainage, elevation, vegetation, land use and land cover data. The data were prepared from information provided by national mapping and other organisations worldwide.
Purpose
The concept of Global Mapping, and the establishment of an international body for Global Mapping, was first proposed by the Ministry of Construction of Japan (MOC) in 1992; and in 1994 the Geographical Survey Institute of Japan (GSI) proposed the first draft Map Specifications. The project currently involves the participation of many interested nations. The main objective of this global project is to bring all nations and concerned organisations together to develop and provide easy and open access to global digital geographic information at a scale of 1:1 million. This would be used to facilitate the implementation of global agreements and conventions for environmental protection, for monitoring of major environmental phenomena and to encourage economic growth within the context of sustainable development. As part of this objective, a Global Map product will be developed to this specification. The Global Map will also contribute to the development of a Global Spatial Data Infrastructure

Data Quality Information
Attribute Accuracy Report
Completeness is a measure of the degree to which all features listed in the technical specification have been captured, in accordance with the selection criteria, definitions and other rules specified. All instances of a feature and its attribute values that meet the selection criteria and appear on the source materials are captured. The data is generalised so the selection of features is to some extent subjective.
Logical Consistency Report
Logical consistency is a measure of the degree to which data complies with the technical specification. Logical consistency was validated by tests to check that table and file names are set out as in the Data Dictionary. Graphical tests checking such things as intersections, polygon closure, minimum sizes of polygons and length of linear features were also carried out.
Completeness Report
Completeness is a measure of the degree to which all features listed in the technical specification have been captured, in accordance with the selection criteria, definitions and other rules specified. All instances of a feature and its attribute values that meet the selection criteria and appear on the source materials are captured. The data is generalised so the selection of features is to some extent subjective.
Horizontal Positional Accuracy Report
For horizontal accuracy, 90% of points will be within 2km of their actual location. In the case of data obtained from satellite images, the maximum error is less than or equal to 0.5km.
