Description:

Abstract:

Ground control points and checkpoints were collected during Global Positioning System (GPS) surveys conducted between September 6, 2014 and September 18, 2016 along the northern coast of Barter Island, Alaska. Data were acquired and post-processed using precise positioning and used to co-register and assess accuracy of photogrammetric data sets.

Purpose:

The data were acquired in support of a larger study to demonstrate the utility of using structure-from-motion photogrammetric methods for deriving digital elevation data using imagery acquired from a fixed-wing aircraft in remote environments. Companion data sets, including orthophotomosaics, elevation point clouds, and digital surface models are used to evaluate fine-scale morphological and volumetric change to beaches and permafrost bluffs.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

GPS data were acquired using precision Ashtech Z-Extreme receivers and external antenna mounted on a separate tripod or survey rod. Data were acquired kinematically at both fixed locations and along walking transects. Data were differentially post-processed using an On-line Positioning User Service (OPUS) derived base station solution based on GPS data from an average over multiple days.

Logical_Consistency_Report:

The differential processed GPS was checked for outliers and anomalies.

Completeness_Report:

Data set is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Horizontal accuracy at static locations is approximately ±0.03 m. Horizonatal positions of points along the walking survey transects could be biased upward by 5 to 10 cm because of the data collection techniques.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

Vertical accuracy at static locations is approximately ±0.03 m. Vertical positions of points along the walking survey transects could be biased upward by 5 to 10 cm because of the data collection techniques.

Process_Step:

Process_Description:

USGS field crews collected GPS coordinates on September 6 and 7, 2014 at a stationary base station, 3 fixed, monumented locations (CP-3, TSM-1, and TSM-2) and along 9 (walking) transects across low tundra bluffs that coincided with electrical resistivity survey transect (ERT) locations. The base station was an Ashtech Z-Extreme GPS receiver and external 2.25 m high antenna mounted on a tripod secured on the eastern railing to the ramp of the U.S. Fish and Wildlife bunkhouse in Kaktovik, Alaska. The coordinates of the base station were determined from On-line Positioning User Service (OPUS) solution based on GPS data from an average over multiple days. The rover was an Ashtech Z-Extreme GPS. The rover antenna was mounted on 2-m survey rod with a bubble level and 5-cm diameter, flat base. Rover data were post-processed using the OPUS derived position of the base station position and the PPP method in Grafnav software. A single position for each of the 3 monument points was determined from the mean value of a cluster of points collected over 1 minute. Positions along the walking transects along the ERT lines were edited to remove obvious spurious and duplicate points, but may be biased upward 5-10 cm because of the data collection techniques.

Process_Step:

Process_Description:

USGS field crews collected GPS coordinates on September 17 and 18, 2016 at a stationary base station, 4 fixed, monumented locations (unnamed, CP-3, TSM-1, and TSM-2) and at 4 circular concrete pads at the former Petroleum-Oil-Lubricant (POL) tank farm of the Radar Station at Barter Island, Alaska. The base station was an Ashtech Z-Extreme GPS receiver and external 2.25 m high antenna mounted on a tripod secured on the eastern railing of the ramp to the U.S. Fish and Wildlife bunkhouse in Kaktovik, Alaska. The coordinates of the base station were determined from On-line Positioning User Service (OPUS) solution based on GPS data from an average over multiple days. The rover was an Ashtech Z-Extreme GPS. The rover antenna was mounted on 2-m survey rod with a bubble level and 5-cm diameter, flat base. Rover data were post-processed using the OPUS derived position of the base station position and the PPP method in Grafnav software. A single position for each of the 3 monument points was determined from the mean value of a cluster of points collected over 1 minute. Positions along the walking transects at the POL pads represent the ground surface.
