Data Management Plan
DMP Template v2.0.1 (2015-01-01)
Please provide the following information, and submit to the NOAA DM Plan Repository.Reference to Master DM Plan (if applicable)
As stated in Section IV, Requirement 1.3, DM Plans may be hierarchical. If this DM Plan inherits provisions from a higher-level DM Plan already submitted to the Repository, then this more-specific Plan only needs to provide information that differs from what was provided in the Master DM Plan.
1. General Description of Data to be Managed
Orthophotos combine the image characteristics of a photograph with the geometric qualities of a map. The primary digital orthophoto is a 15cm GSD resolution with tiles measuring 1500 x 1500 meters cast on the Universal Transverse Mercator Zone 17N on the North American Datum of 1983 (NAD83/2007). The aerial photography used to create the digital images was acquired between February 16th and March 8th, 2010.
Notes: Only a maximum of 4000 characters will be included.
Notes: Data collection is considered ongoing if a time frame of type "Continuous" exists.
Notes: All time frames from all extent groups are included.
Notes: All geographic areas from all extent groups are included.
(e.g., digital numeric data, imagery, photographs, video, audio, database, tabular data, etc.)
(e.g., satellite, airplane, unmanned aerial system, radar, weather station, moored buoy, research vessel, autonomous underwater vehicle, animal tagging, manual surveys, enforcement activities, numerical model, etc.)
2. Point of Contact for this Data Management Plan (author or maintainer)
Notes: The name of the Person of the most recent Support Role of type "Metadata Contact" is used. The support role must be in effect.
Notes: The name of the Organization of the most recent Support Role of type "Metadata Contact" is used. This field is required if applicable.
3. Responsible Party for Data Management
Program Managers, or their designee, shall be responsible for assuring the proper management of the data produced by their Program. Please indicate the responsible party below.
Notes: The name of the Person of the most recent Support Role of type "Data Steward" is used. The support role must be in effect.
4. Resources
Programs must identify resources within their own budget for managing the data they produce.
5. Data Lineage and Quality
NOAA has issued Information Quality Guidelines for ensuring and maximizing the quality, objectivity, utility, and integrity of information which it disseminates.

Process Steps:
- 2010-10-01 00:00:00 - The Digital Orthoimagery is comprised of 8 bit color imagery captured by the PanoramiX camera. Using the Preprocessor software, data was unpacked and indexed. A QA/QC process was performed to ensure integrity of the raw data. An automated radiometric calibration was performed as an initial adjustment to aid in creating consistent imagery. GPS data captured during flight was processed and integrated into the project, after which a block solution was calculated in the Dataviewer software. A QA/QC process was performed on this solution to identify any anomalies. This was done by reconstructing various points in the solution. Ground Control was imported into the Dataviewer software and measured in order to refine the solution. The surface model from the 2009 Horry County project, with some updated areas, was imported into the Dataviewer software. The imagery was then rectified for each flight line using the refined block solution and the imported surface model. A QA/QC process was performed to check for any rectification errors. The rectified imagery was exported from the Dataviewer software along with a reduced resolution mosaic, or Quicklook, of each of these imagery strips. The quicklooks were radiometrically adjusted using Earthdata Proprietry software and then imported into the Pixel Factory software along with the full resolution mosaic flight lines. The histogram from the quicklook was applied to the full resolution imagery. Mosaic lines were placed, joining the imagery strips. In initial QA/QC was performed by the technician to ensure that the mosaic lines were appropriately placed and that there was appropriate imagery coverage. The final imagery data set was removed from the Pixel Factory environment in a process called "packaging" where the individual tiles are created. The created tiles are reviewed again for anomalies and interactive radiometric adjustment applied where needed. QA/QC was performed looking for anomalies, smears and other indications of problems within the digital orthophoto creation process, interactive radiometric adjustment applied where needed. Two additional radiometric adjustments are applied to the completed orthos in Adobe Photoshop. The first is a sharpening mask filter; this filter is used to help increase sharpness of a digital image. The basis for this filter is to locate pixels that differ in value from surrounding pixels by the threshold specified. It then increases the pixels contrast by the value identified. For neighboring pixels specified by the threshold, the lighter pixels get even lighter and the darker pixels get even darker based on the specified amount. The changes made maintained the integrity of the original histogram curve. The imagery is then Projected to the appropriate co-ordinate system and recut to the tiling scheme required for delivery. The final digital ortho product was GEOTIFF files. All data was delivered on external hard drives.

6. Data Documentation
The EDMC Data Documentation Procedural Directive requires that NOAA data be well documented, specifies the use of ISO 19115 and related standards for documentation of new data, and provides links to resources and tools for metadata creation and validation.

7. Data Access
NAO 212-15 states that access to environmental data may only be restricted when distribution is explicitly limited by law, regulation, policy (such as those applicable to personally identifiable information or protected critical infrastructure information or proprietary trade information) or by security requirements. The EDMC Data Access Procedural Directive contains specific guidance, recommends the use of open-standard, interoperable, non-proprietary web services, provides information about resources and tools to enable data access, and includes a Waiver to be submitted to justify any approach other than full, unrestricted public access.
All orthophotography is the property of the USGS and Horry County
