2015 Southwest Florida RCD30 4-Band 8 Bit Imagery

These files contain imagery data collected with an RCD30 camera as 8-bit RGBN TIFF images. Imagery was required 1000m seaward of the land/water interface or to laser extinction (whichever came first), while topographic lidar data were required 500m inland of the land/water interface. Data coverage generally extends along the southwest of Florida from Anclote Key to Marco Island. Horizontal positions, provided in meters, are referenced to the North American Datum (NAD83) 2011, projected to Universal Transverse Mercator (UTM) Zone 17 North in meters. Vertical positions were acquired to the NAD83 2011 ellipsoid.Imagery was rectified, upon request, using a Bare Earth elevation model in order to create mosaics with improved aesthetics. Positions of buildings could be in error and imagery should not be used for digitizing structures. The data file naming convention is based on the year, project, area name, clip boundary, product type, number of bands, and altitude and in some cases a dataset name or a number to indicate multiple files. An example file name is "2015_NCMP_FL_01_5mGrid_RGB where 2015 is the year of data collection, NCMP is the Effort under which data were collected, "RGB" is the product type, In rare cases file names may include whether data was collected at a nominal range of high tide (HT) or low tide (LT). The supplementary files are of the same name.

These data are not attributed. | Quantitative Value: None | Quantitative Test Explanation: These data are not attributed.

The data positions were obtained using post processed KGPS methods. The horizontal accuracy of the true color imagery operation is 1 meter at 2 sigma. Gross offsets in imagery data may be due to DEM affects or unforseen timing offsets caused by missed or unknown camera trigger times.

This data set covers the spatial extent of true color imagery data obtained during this survey.

During inspection and QC of the true color imagery data, flightline to flightline accuracies met the RCD30 sensor specifications.
