The purpose of this guidance is to provide the demonstrator with a more concise description for the submission of data upon the completion of a geophysical survey at the UXO Standardized Sites. The primary purpose of the UXO Standardized Test Site Program is to develop and demonstrate advancements in detection technologies meeting the exit criteria established for detection/discrimination performance, production rates, and costs. The data deliverables establish baselines for technologies and quantify performance levels of individual vendors. The current requirements of raw data definitions address data formats without merged positional information or a common database. Sensor specific formats are often unknown and more than one data stream is often present. While this requirement is necessary to verify that data has in fact been captured, it lacks the details needed to fill in the gaps.

Raw sensor data is a sensor specific, rudimentary form of data with the corrected GPS (or other locating system) diurnal variations, applied by the sensor system prior to being subjected to post processing algorithms. (i.e., raw data for a magnetometry system would be the magnetic flux readings in nano-Tesla relative to time and position).

Processed sensor data is result of the demonstrator's manipulation of the raw data collected by their sensor. The processed data is the equivalent to a dig sheet. This program requires that there be two stages of processed data submitted, response stage and discrimination stage. The demonstrator will be scored based on the information provided in the processed sensor data.

Data Deliverable #1: (Due on-site upon completion of survey) Raw sensor data/output streams of each hardware-sensing component recorded by the acquisition system. Supporting documentation/explanation is required regarding data formats.

Data Deliverable #2: (Due 30 days after last day of acquisition), the demonstrator is required to submit minimally processed, georeferenced data set. This data set should provide adequate content for objective utilization by other approved parties. The structure of the georeferenced dataset will not be predefined, but ASCII format is recommended. At a minimum, this should include positional information and geophysical sensor readings (separate channels for raw and final). If acquired, the platform orientation, GPS data, and database time channels should also be included in the database. A concise explanation describing the analysis procedures and classification approach must accompany the data set that clearly defines the target characteristics used for classification and the selected thresholds.

Data Deliverable #3: (Due 30 days after last day of acquisition) The final dig list in Excel spreadsheet as provided in the above format.

Letter - Combined with Number provides grid location on the blind test grid
Number - Combined with Letter provides grid location on the blind test grid

Response Stage - The Response Stage scoring evaluates the ability of the system to detect emplaced targets without regard to ability to discriminate ordnance from other anomalies. For the Response Stage, the demonstrator provides the scoring committee with the location and signal strength of all anomalies that the demonstrator has deemed sufficient to warrant further investigation and/or processing as potential emplaced ordnance items. This list is generated with minimal processing (e.g., this list will include all signals above the system noise threshold). As such, it represents the most inclusive list of anomalies.

Discrimination Stage - The Discrimination Stage evaluates the demonstrator's ability to correctly identify ordnance as such, and to reject clutter. For the same locations as in the Rresponse Stage anomaly list, the Discrimination Stage list contains the output of the algorithms applied in the discrimination-stage processing. This list is prioritized based on the demonstrator's determination that an anomaly location is likely to contain ordnance. Thus, higher output values are indicative of higher confidence that an ordnance item is present at the specified location. For electronic signal processing, priority ranking is based on algorithm output. For other systems, priority ranking is based on human judgment. The demonstrator also selects the threshold that the demonstrator believes will provide "optimum" system performance, (i.e., that retains all the detected ordnance and rejects the maximum amount of clutter).

Classification - Demonstrator determines if the item is ordnance (O), clutter (C) or blank (B).

Type - If a demonstrator determines an item is Ordnance, provide the caliber. A demonstrator leaves this blank for clutter or in the blind grid a blank square.

Depth - Demonstrator identifies the depth (meters) to the top of the ordnance item.

Azimuth - Demonstrator provides the direction of the Ordnance relative to magnetic north. 0^o azimuth indicates nose of the projectile facing magnetic north.

Dip - Demonstrator provides the incline of Ordnance in degrees, (+) positive, indicates nose of the projectile facing down, (-) negative, indicates nose of the projectile facing up.
