Guida is currently providing on-call land surveying and mapping services to the Los Angeles County Sanitation Districts (District). The scope of services under this three year contract includes control and topographic design surveys, aerial photogrammetric mapping and digital orthophotography, boundary and right of way surveys, legal descriptions and plats, construction surveys, and as-built mapping.
A recent task order included the development of topographic mapping and digital orthophotography for a portion of Bullis Road from Lynwood Road to Cortland Road, and the collection and identification of approximately 15 sewer manholes along the Bullis Road to Temple Road Trunk Sewer Line. The topographic mapping was tied into County benchmarks and delivered in the District’s MicroStation and InRoads CAD standard. The digital orthophotography was captured with Guida’s Phantom 4 UAV system and tied into the horizontal and vertical controls established for the project.
