Geospatial Positioning Accuracy Standards, Part 4: Architecture, Engineering, Construction, and Facilities Management
U.S. Army Corps of Engineers
PART 4 provides accuracy standards for engineering drawings, maps, and surveys used to support planning, design, construction, operation, maintenance, and management of facilities, installations, structures, transportation systems, and related projects. It is intended to support geospatial mapping data used in various engineering documents, such as architectural, engineering, and construction (A/E/C) drawings, site plans, regional master planning maps, and related Geographical Information System (GIS), Computer-Aided Drafting and Design (CADD), and Automated Mapping/Facility Management (AM/FM) products. These products are typically created from terrestrial, satellite, acoustic, or aerial mapping techniques that output planimetric, topographic, hydrographic, or feature attribute data.
This standard defines accuracy criteria, accuracy testing methodology,
and accuracy reporting criteria for object features depicted on A/E/C
spatial data products and related control surveys. It references
established voluntary standards that may be used for some smaller-scale
A/E/C mapping applications. In addition, Appendix A contains general
guidance for specifying accuracy criteria for selected types of A/E/C
features or control surveys. Using the standards and guidance contained
in this section, end users of A/E/C products (e.g., planners, designers,
constructors) can specify surveying and mapping accuracy requirements
needed for their projects or specific CADD/GIS layers, levels, or entities.
From these specifications, data producers (e.g., surveyors, mappers, photogrammetrists)
can determine the instrumentation, procedures, and quality control processes
required to obtain and verify the defined accuracies.
