Specialized And Technology
Specialized & Technology Surveying Services in Northern California
Some projects call for more than boundary lines and topographic data. When the work involves aerial mapping, water storage capacity, or a large-scale control framework, you need survey services grounded in specialized technology and technical judgment developed over 80+ years of combined experience. BC Land Surveying's licensed team applies photogrammetric surveys, reservoir volume surveys, and control networks to give developers, agencies, engineers, and property owners across Sonoma, Marin, and Napa Counties precise data for work that goes beyond conventional survey methods. Each service in this category draws on aerial technology, hydrographic technique, and geodetic accuracy to solve problems a total station and a property line can't address alone. Whatever the deliverable, you get data that holds up under scrutiny, on a timeline that matches your project.
Our Specialized & Technology Surveying Services
This category covers survey work built around advanced tools and techniques: aerial imagery, water volume calculation, and geodetic control. These services support engineering, agricultural, environmental, and infrastructure projects that require data beyond what a standard boundary or topographic survey can provide on its own.
01
Photogrammetric Surveys
Aerial imagery converted into precise measurements and mapping data. Ideal for large sites, difficult terrain, or projects requiring detailed topographic information without extensive ground access.
02
Reservoir Volume Surveys
Accurate volumetric data for reservoirs, ponds, and impoundments. Supports irrigation planning, water rights documentation, and agricultural water management across Sonoma, Marin, and Napa vineyards and ranches.
03
Control Networks
Survey control points that anchor accuracy across large or multi-phase projects. Essential infrastructure for construction, subdivision, and engineering work spanning extended timelines or multiple survey crews.

WHY CHOOSE US
Why Northern California Trusts BC Land Surveying for Specialized Survey Work
Specialized survey work demands more than equipment. It demands judgment built from experience. Our team brings 80+ years of combined experience to projects that require aerial mapping, water volume calculations, and control network design, work that leaves little room for error. Licensed Professional Land Surveyors oversee every specialized project, applying the same precision and accountability that defines our boundary and construction work. We understand the terrain across Sonoma, Marin, and Napa Counties, from vineyard water storage ponds to multi-phase development sites, and we build data you can hand to an engineer, an agency, or a title company with confidence. Responsiveness matters here too. Specialized projects often move on tight timelines tied to permitting, financing, or construction schedules, and we're built to keep pace with them, without cutting corners on the accuracy your project depends on.
Frequently Asked Questions
Specialized surveying raises questions that don't come up with a standard boundary or topographic job. Here are answers to what Northern California clients ask most.
What is a photogrammetric survey, and when do I need one?
A photogrammetric survey converts aerial imagery, captured by drone or aircraft, into accurate measurements and mapping data. It's a strong option for large or hard-to-access sites, steep terrain, or projects where extensive ground survey work would be slow or costly. Developers and engineers often use photogrammetric surveys during early planning stages to capture topographic detail across an entire parcel quickly. If your project covers significant acreage or terrain that's difficult to walk, this method can deliver the data you need without sacrificing accuracy.
How does a reservoir volume survey work, and who typically needs one?
A reservoir volume survey measures the storage capacity of a pond, reservoir, or impoundment, typically by combining bathymetric data with a topographic survey of the surrounding banks. Vineyard owners, ranchers, and agricultural operations across Sonoma, Marin, and Napa Counties rely on these surveys for irrigation planning, water rights documentation, and permitting that requires proof of storage capacity. Municipalities and water districts use them too, for infrastructure planning and compliance reporting. If you need documented, defensible volume data for a water storage feature, this is the service that provides it.
What is a control network, and why does my project need one?
A control network is a set of precisely located survey points that anchor accuracy across a site, especially on large or multi-phase projects. Once established, every subsequent survey task, staking, topographic work, or boundary verification references the same fixed points, which keeps data consistent even if the project spans months or years and multiple survey crews. Developers managing phased subdivisions or long-term construction projects benefit most, since a strong control network keeps small errors from compounding as the project moves forward.
Do you use drones for specialized and technology surveys?
Yes. Drone-based aerial photography supports our photogrammetric surveys and can supplement reservoir volume and control network projects where aerial data adds efficiency or accuracy. Drone technology lets us capture detailed imagery across large or difficult terrain quickly, then convert it into precise, usable survey data. We pair that aerial capability with traditional field methods and GPS/GNSS equipment, so every project gets the right mix of technology for the terrain and the deliverable.
Which areas of Northern California do you serve for specialized surveying?
We provide specialized and technology surveying services throughout Sonoma, Marin, and Napa Counties, our primary service area. This includes vineyard and agricultural properties, development sites, and infrastructure projects across the region. Projects outside these three counties can be accommodated on request. If you're unsure whether your project qualifies or which specialized service fits your needs, contact our team and we'll help you scope it out.
