The document discusses how the USGS's geospatial datasets and services will be affected by the modernization of the National Spatial Reference System (NSRS). It notes that elevation datasets associated with 3DEP will be most impacted. Preparations include requiring machine-readable coordinate systems and messaging support for GPS on benchmarks. There is excitement about improved geoid and datum models aligning better with global systems. However, there is also concern about the challenges of transforming vast existing NAD83 datasets, such as 11 trillion lidar points. Key needs are the NADCON8 transformation tool and its incorporation into various software.
