Accurate ground control is the foundation of dependable solar farm mapping. Survey-grade Ground Control Points, or GCPs, help ensure that aerial imagery, orthophotos, terrain models,
Ground Control Points, or GCPs, anchor corridor and mobile mapping workflows to a verified coordinate reference system. They help correct positional drift along long, narrow
Ground control points anchor coastal mapping to verified, survey-grade accuracy by connecting shoreline, infrastructure, and bathymetric data to a consistent real-world reference frame. For projects
Airport mapping accuracy standards demand survey-grade Ground Control Points, or GCPs, validated through rigorous field and quality-control processes. CompassData collects GCPs using dual-frequency GPS and
Independent geospatial accuracy verification confirms whether mapping and survey data meet their stated positional standards through a qualified third-party audit. When a project depends on
Archive GCPs are well suited to budget-conscious projects that need a fast turnaround, while new collection delivers site-specific accuracy through CompassData’s field-proven process. New collections
