Acknowledgment of the U.S. Geological Survey, St. Petersburg Coastal and Marine Science Center, as a data source would be appreciated in products developed from these data, and such acknowledgment as is standard for citation and legal practices for data source is expected. Sharing of new data layers developed directly from these data would also be appreciated by the U.S. Geological Survey staff. Users should be aware that comparisons with other datasets for the same area from other periods may be inaccurate because of inconsistencies resulting from changes in photointerpretation, mapping conventions, and digital processes over time. These data are not legal documents and are not to be used as such.
The purpose of this project was to produce a highly detailed and accurate digital elevation map for the Big Sandy Creek Corridor Unit of Big Thicket National Preserve in Texas for use as a management tool and to make these data available to natural-resource managers and research scientists. To ensure that SPCMSC data management protocols were followed, this survey was assigned a USGS field activity number (FAN), 13LTS02. Additional survey and data details are available at http://cmgds.marine.usgs.gov/fan_info.php?fan=13LTS02.
Are there legal restrictions on access or use of the data?
