Hunter Island UAV Survey June 2016

Hakai Institute UAV and Survey data for Hunter Island. Conducted June 2016

Purpose: The goal is to gather spatial data for Hauyat cultural site and the north end of Hunter Island. We aim to produce high resolution imagery, 3D surface models, and a survey datum point for future archaeological work. Site description: Hauyat is located south of Bella Bella, B.C. on the north end of Hunter Island. Over millennia, the Hauyat landscape has been modified from the lower intertidal to the terrestrial foreshore to include clam gardens, fish traps, root gardens, berry patches, orchards, shell middens, settlements, rock art, and defensive sites. At the center of this landscape is a large, terraced village (site FaTa-10) with at least 8 house depressions. The site is approximately ~ 80 meters wide and consists of three main platforms. From the central terrace a 0.5 meter high berm spans 100 meters to the southwest and 50 meters to the southeast. Elevation modelling using the RTK survey equipment will be employed to map the village site and features (e.g., house depressions) and spatial data on the surrounding landscape and archaeological features (e.g., clam gardens) will be gathered using UAV (unmanned aerial vehicle) imagery capture.

Early morning flights to catch the low tide resulted in lower light conditions during flights. Weather was overcast with low level clouds with occasional rain.

Two strategies were used for the imagery collection. 1) June 6th: Large area / higher elevation flights to cover the north coast of Hunter Island. High visibility GPS targets were placed over the 7 kilometer x 2.5 kilometer study area. Dual drone imagery capture was used to cover the area as fast as possible at low tide.

2) June 7, 8th: Multilevel UAV flights over the main village site and bay on Hunter Island. Low level flights were conducted just over the tree tops ~ 60 meters or lower to capture high resolution imagery. 5 - 10 meter test flights were conducted over exposed fish trap locations to produce sub cm resolution models. Higher flights ~ 120 - 150 meters covered the bay to include the village site / fish traps / and defensive islands.

UAV data processing was conducted using Pix4D software.
