GEOSPATIAL DATA AND SYSTEMS
1. Purpose. This manual provides detailed technical guidance and procedures for compliance
with the policy in Engineer Regulation (ER) 1110-1-8156, Policies, Guidance, and Requirements
for Geospatial Data and Systems, which establishes general criteria for the use and development
of geospatial technologies throughout the U.S. Army Corps of Engineers (USACE). This
manual includes, but is not limited to, geospatial system development and utilization as well as
the acquisition, processing, storage, distribution, and utilization of geospatial data and systems.
2. Applicability. This manual applies to all USACE Commands having civil works, military
construction, and environmental restoration responsibilities. It specifically applies to functional
areas having responsibility for regulatory investigations and studies, planning studies, real estate,
emergency operations, and other functions that involve geospatial technologies and services for
surveying (hydro and topo), mapping, Computer Aided Design and Building Information
Modeling (CAD/BIM), remote sensing, database development, and modeling. It also applies to a
variety of geospatial products, including river and harbor maps; navigation charts; inundation
mapping; vulnerability and risk analysis; recreation and lake management activities; dredge site
placement; real estate tract or parcel maps; engineering and construction drawings; survey
reports; reconstruction, restoration and rehabilitation efforts; environmental stewardship;
environmental studies; Hazardous, Toxic, and Radioactive Waste (HTRW) studies; shoreline
studies; and channel condition reports.
3. Distribution. This publication is approved for public release; distribution is unlimited.
4. Discussion
. This manual provides guidance for implementing the development and
maintenance of a unified and comprehensive use of geospatial technologies across USACE. It
outlines a corporate approach to implementing geospatial technology that meets functional
business process requirements in harmony with state, local, and Federal agency programs to
more efficiently produce geospatial products and serve customers. It promotes a holistic and
integrated approach to managing geospatial data and information that supports both the
comprehensive management of watersheds and military installation management. This manual
outlines a framework for sharing geospatial data with other Federal, state, and local partners in
