This publication, Army Techniques Publication ATP 3-34.80 Geospatial Engineering June 2014, provides doctrine for geospatial engineering operations at all echelons. It is an extension of FM 3-34 and is linked to joint and other Army doctrine to ensure its usefulness for operational level commanders and staff. This manual serves as a guide for the integration of geospatial engineering in support of unified land operations at all echelons, with added focus on describing geospatial engineering within divisions and brigades. The principal audience for ATP 3-34.80 is engineer commanders and staff officers, but all Army leaders will benefit from reading it. Trainers, combat developers, and educators throughout the Army will also use this manual. This manual will help other Army branch schools in teaching the integration of geospatial engineering capabilities into Army operations. This manual describes the application of geospatial engineering in support of Army forces conducting unified land operations. It also acknowledges that Army doctrine remains dynamic-balancing current capabilities and situations with projected requirements for future operations. As geospatial engineer capabilities continue to improve through organizational changes, technological advancements, and emerging best practices, leaders and planners at all levels will be charged to leverage those improvements and adapt the processes and procedures that are described in this manual to meet the demands and provide the most effective geospatial support possible to the commander. ATP 3-34.80 is built directly on new or revised joint and Army doctrine, notably Army capstone doctrine that is found in ADP 3-0 and FM 3-34. This revision also captures the results of the lessons learned and the observations from recent operational experiences in Afghanistan, Iraq, and other locations, to include the challenges of operating in complex terrain. ATP 3-34.80 is organized into four chapters, with supporting appendixes that sequentially describe geospatial engineering, the roles and responsibilities for integrating geospatial support at the various echelons, and the integration of geospatial engineering within the Army operations process. A brief description of the chapters and appendixes follows: Chapter 1, Support to Unified Land Operations, describes the role of geospatial engineering in supporting unified land operations. It also describes the critical roles that geospatial engineering units and staffs have in providing geospatial engineering in support of Army operations. Chapter 2, Army Geospatial Enterprise, focuses on defining the Army Geospatial Enterprise (AGE) and SSGF. Chapter 3, Roles and Responsibilities, discusses the geospatial engineering capabilities that reside within the echelons above brigade down to the brigade combat team (BCT). Chapter 4, Geospatial Support Integration, focuses on how to integrate geospatial engineering capabilities into the Army operations process. Appendix A provides a metric conversion chart. Appendix B, Geospatial Products, provides examples of geospatial products that aid in terrain visualization and support decisionmaking. Appendix C, Geospatial Data Management, provides information on gathering, storing, and disseminating relevant digital terrain data that supports operations and enables decisionmaking. Appendix D, Terrain Characteristics, describes the six characteristics of terrain that geospatial engineers analyze in determining the terrain effects on operations. Appendix E, Systems and Software, describes the DTSS family of systems and the DCGS-A that is used to support mission requirements. The DTSS has been absorbed under the DCGS-A program of record, but it is still in use across the geospatial force. The DTSS will be replaced in the near future.
