Monday-Friday, 8 am - Noon, 1 pm - 5 pm, CST Request to speak to a GIS specialists originator mapDigital Point dataset representing hard control monument or benchmark locations used by the GSA to collect Gulf of Mexico-fronting beach profiles on Dauphin Island and the Morgan Peninsula. The data were developed as part of ongoing studies on coastal erosion as part of the Alabama Coastal Zone Management Program. Funding for this project was provided by the Alabama Department of Conservation and Natural Resources, State Lands Division, Coastal Section (ADCNR-Coastal), in part, by a grant from the National Oceanic and Atmospheric Administration, Office of Ocean and Coastal Resource Management. completed GIS Specialist Geological Survey of Alabama GIS 205-349-2852 205-349-2861

Federal, State, or local regulatory bodies are not to reassign to the originators any authority for the decisions they make. Photographic or digital enlargement of these maps to scales greater than those at which they were originally delineated can cause misrepresentation of the data. If enlarged, the data will not yield greater real detail, although it may reveal fine-scale irregularities below the intended resolution of the data. Similarly, where this dataset is used in combination with other data of higher resolution, the resolution of the combined output will be limited by the lower resolution of these data.
