Other_Citation_Details:

The DCW was developed in conformance with a new Geographic Information System (GIS) data format known as the Vector Product Format (VPF), which is a U.S. Department of Defense Military Standard. The National Imagery and Mapping Agency (formerly Defense Mapping Agency) will use VPF for future digital vector products developed at different resolutions and with different data.

Description:

Abstract:

The South America Town (SATOWN) coverage is a graphic point (node) representation depicting the towns (urbanized areas) of Argentina, Bolivia Brazil, Chile, Colombia, Ecuador, the Falkland Islands, French Guiana, Guyana, Paraguay, Peru, Suriname, Uruquay, and Venezuela in South America. It is a 1:1,000,000-scale vector basemap with geographic and attribute data that can be accessed, queried, and displayed.

Purpose:

The SATOWN coverage was processed for the Inter-American Geospatial Data Network (IGDN) at the EDC. The IGDN provides access to geospatial data in partnership with business, universities, nongovernment organizations, and governments in the Western Hemisphere.

Supplemental_Information:

The SATOWN data set was converted from the Vector Product Format (VPF) Digital Chart of the World (DCW). The DCW is a vector data base developed by the National Imagery and Mapping Agency (NIMA), formerly the Defense Mapping Agency (DMA), in support of Geographic Information System (GIS) applications. Feature content is based on the 1:1,000,000-scale Operational Navigation Charts (ONC) series. Additional information about the Digital Chart of the World is in the report "Development of the Digital Chart of the World". The DCW database is described in detail in the Military Specification, dated 13 April 1992, MIL-D-89009, and the DCW product in Vector Product Format (VPF) is described in the Military Standard (MIL-STD-600006). The DCW VPF version is in the public domain.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

The attributes refer to the characteristics of the source Operational Navigation Chart (ONC) series. The theme is cartographically based and does not include extensive attribute lists.

Quantitative_Attribute_Accuracy_Assessment:

Attribute_Accuracy_Value: Unknown

Attribute_Accuracy_Explanation:

Digital Chart of the World feature coding reflects the characteristics of the symbolization rules defined in the ONC product specification rather than a strict one-to-one correspondence to all features present in the real world.

Logical_Consistency_Report: Point features present.

Completeness_Report:

No changes were made to the original Digital Chart of the World Data Base.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The absolute horizontal accuracy of the DCW for all features derived from Operational Navigation Charts (ONCs) is 2040 meters (6700 feet) rounded to the nearest 5 meters at 90% Circular Error (CE), World Geodetic System (WGS84). These figures are the root sum square of the original data DMA Operational Navigation Chart (ONC) sheet positional errors plus the additional error introduced by the of the World production process.

Quantitative_Horizontal_Positional_Accuracy_Assessment:

Horizontal_Positional_Accuracy_Value: .00010 meters

Horizontal_Positional_Accuracy_Explanation:

Ellipsoid derived from adopted model of Earth. World Geodetic System 84 (WGS84) has same dimensions within accuracy shown.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

The absolute vertical accuracy of the DCW is the same for the original Operational Navigation Charts (ONCs) at 90% Linear Error (LE), Mean Sea Level (MSL).

Quantitative_Vertical_Positional_Accuracy_Assessment:

Vertical_Positional_Accuracy_Value: .00010 meters.

Vertical_Positional_Accuracy_Explanation: Resolution as reported.

Process_Step:

Process_Description:

The data were acquired from the National Imagery and Mapping Agency (NIMA), formerly the Defense Mapping Agency (DMA), on CD-ROM in Vector Product Format (VPF). In order to perform GIS functions, the DCW data base must be used in conjunction with user-supplied GIS software. DCW employs a feature and attribute coding structure that is tied to the codes used in the ONC series. Using VPFIMPORT, the DCW tiles covering the region of South America were extracted and converted to an ARC/INFO workspace. The VPF version of the DCW tiling scheme is retained in the ARC/INFO database. Further processing included the selection of the urbanized areas (built-up areas) theme, the tiles were MAPJOINed, CLIPped, and CLEANed with the output coverage as SATOWN (South America Town).
