  • Comments:

    We reprojected the data from its native projection into WGS 1984 Web Mercator Auxiliary Sphere (WKID: 3857; Authority: EPSG). While digital data can be displayed precisely at any scale, data accuracy remains constant. Although the user may increase the displayed scale, uncertainties and errors in raster location remain tied to original collection resolution. Users must recognize these limitations when zooming in farther than the mapped resolution for a given dataset and treat resulting visual representations with appropriate caveats.
