SurvTech Solutions recently completed a task order through USACE Jacksonville District supporting the Mogote Stabilization Project in Fort Buchanan, located in Guaynabo, Puerto Rico.
The work consisted of UAV LiDAR and Imagery acquisition, data processing, and ground survey support. This task order is part of a larger effort to determine current Mogote conditions and to provide a base for USACE design, volume analysis initiatives, and improvements in stabilizing the cliff face of the Mogote. UAS Remote sensing played a critical role in capturing the necessary data.
A mogote is a unique formation of isolated residual hills with steep sides typically composed of limestone often surrounded by alluvial planes and have a rounded tower-like shape. The sides are so steep that they are almost vertical.
The Fort Buchanan Mogote has a cliff face roughly one mile long. Considerable erosion over time has made portions of the cliff-face unstable, hence the efforts to stabilize and minimize potential damage to nearby structures.
SurvTech Solutions mobilized to the island in June 2024. They accomplished this project with Blue List UAS Harris H6 Hybrid with a Riegl VUX LiDAR sensor and WingtraOne Gen II vertical take-off. They were both configured to meet USACE Aviation requirements.
The flight plans were designed to maximize LiDAR and image coverage on the cliff face on the north side of the mogote. LiDAR point density achieved was an aggregate average density of 150 ppsm (points per square meter), and the imagery had a pixel resolution of 1 cm. Processed data included survey-grade LiDAR point cloud, imagery, and ground control.
