Aerial Survey. Deploy drone to capture high-resolution aerial imagery
Aerial Survey. To inform field survey strategies, the CRS will conduct an aerial reconnaissance of survey areas prior to deploying field crews for pedestrian surveys. The goal of aerial survey will be to identify areas that should be pedestrian surveyed or tested within moderate and low potential areas of the construction footprint, without having to walk over the entire area. Aerial survey will also be used for areas that are considered low potential for the presence of archaeological and historic resources. Aerial survey may also be used to identify isolated higher-potential areas for targeted field survey. Aerial surveys will consist of a helicopter traveling low and slow enough to visually inspect the survey area terrain for indications that the area should be pedestrian surveyed. During aerial survey, the crew(s) will collect the following data: • Aerial photographs of the area that was surveyed • GPS tracks of the flight lines • Notations on field maps regarding the vegetation and terrain conditions observed in the survey areas • Written description of the surveyed area, vegetation type, and explanation of why the area did not warrant pedestrian survey • Overview and/or ground surface photos of all areas where pedestrian survey is warranted
Aerial Survey. Aerial surveying is used in conjunction with limited land surveying efforts. Products may require a digital compilation of contours and physical features, digital terrain models and other new technologies such as LIDAR or other reflective or absorption technology. Firms should indicate both preference and expertise with various systems.
