Digital database of the geologic map of Alamagan Volcano, northern Mariana Islands

This digital database should not be used in any manner that violates the spatial resolution of approximately 2 millimeters (0.1 inches) at 1:5,000-scale, or 10 meters (33 feet) on the ground. Although digital geospatial data are not constrained by scale like paper maps, the inherent uncertainty of the source data is transferred to this database. The dataset was edited at a scale of 1:5,000; therefore, no data of higher resolution have been included. Displaying or analyzing the data at larger scales will not provide greater detail, and it may reveal irregularities that were not visible at the intended scale of 1:5,000. If these data are used alongside any higher-resolution digital data, the spatial resolution of the combined dataset will only be equal to that of the lowest-resolution data. This dataset has been approved for release and publication by the Director of the USGS. Although the dataset has been subjected to rigorous review and is substantially complete, the USGS reserves the right to revise the data pursuant to further analysis and review. Furthermore, it is released on condition that neither the USGS nor the U.S. Government may be held liable for any damages resulting from its authorized or unauthorized use. Acknowledgment of the USGS is appreciated in any products derived from this database. All trademarks and trade names are the property of their respective owners. Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government.
