The expert can compare the monuments and control points relied upon, field measurements, bearings and distances, coordinate information, deeds, plats, prior surveys, and the methods used to establish each result. Differences may arise from the evidence selected, measurement procedures, reference systems, or interpretation of existing records. Tracing each survey back through its underlying observations can help identify where the conclusions begin to diverge.
Coordinates are meaningful only in relation to the reference system used to define them. If datasets rely on different datums, projections, epochs, or vertical references, locations or elevations may not align properly until the data are transformed into a consistent framework. NOAA's National Geodetic Survey identifies geodetic datums as the reference foundation used for surveying and mapping.
The analysis can consider the survey method, control network, instrument records, stated accuracy, check points, data resolution, coordinate reference system, and whether the finished map accurately represents the source measurements. Accuracy requirements can vary according to the intended use and mapping method. Current ASPRS standards address positional accuracy for digital geospatial data and include guidance for field surveying of ground control and checkpoints, LiDAR, photogrammetry, and other mapping technologies.
LiDAR can produce dense three-dimensional point data used to represent terrain, elevations, structures, and other surface features. In a dispute, an expert may examine the source point cloud, acquisition specifications, coordinate system, point classification, sampling density, processing, and derived elevation products to determine whether the data support the mapped conclusion. LiDAR should be evaluated as one mapping source rather than assumed to be accurate merely because it is highly detailed.
