  • Optimization Strategies for Geospatial Data on End-User Devices

    Abstract: The ability to quickly disseminate geospatial data across all echelons, particularly those at the tactical edge, is critical to meeting threats described by the Multi-Domain Operations doctrine. The US Army Engineer Research and Development Center, Geospatial Research Laboratory (ERDC-GRL), is researching the optimization of the formats, data models, file sizes, and quality of geospatial products to be exploited by end-user devices (EUDs). This report describes a processing methodology comprising custom software and open-source tools to optimize Army Geospatial Enterprise Standard Sharable Geospatial Foundation and industry-accepted products for exploitation on EUDs. The Integrated Visual Augmentation System (IVAS) was emphasized, but other devices, including the Nett Warrior and Program Executive Office—Soldier targeting systems, were also studied. Additionally, we developed a compression methodology that reduced the size of three-dimensional model data by a factor of 9 without a loss in data quality. A summary of the results describes steps to address remaining technical issues and considers future efforts to further optimize geospatial data for additional EUDs and tactical applications.
