No surveyed Ground Control Points were used during the processing. The dataset was therefore georeferenced using the UAV’s internal positional information only. No independent accuracy assessment was undertaken; therefore, the positional accuracy of the dataset has not been independently verified. As the imagery was not acquired or processed for accurate mapping or survey purposes, no Ground Sampling Distance (GSD) has been specified, and no photogrammetric processing or accuracy report is available for this item. > [!WARNING] > This orthomosaic is intended for visual reference, site awareness, and general progress-record purposes only. > > It should not be used for precise measurement, setting out, design verification, engineering assessment, asset positioning, boundary definition, or any other survey-grade application. > [!TIP] > Any use requiring reliable spatial accuracy should refer to the Minimum Snow Cover (MSC) dataset survey. unrestricted Open Access (Anonymous) license This information is licensed under the Creative Commons Attribution-NoDerivatives 4.0 International Licence (CC BY-ND 4.0).
