There’s work to do.

  • Wind / PV Generation as Percentage of US Total, 2016 2%
  • Wind / PV Generation, Percentage of Carbon-Free US Total (2050) 50%

GW of Wind / PV Capacity Needed by 2050

SOA helps you get it done.

  • Time Savings vs. RTK GPS (60 Acres) 97%
  • RMSE vs RTK-GPS 30%
  • Cost Savings vs. LiDar or Survey 10%


Drone-Based Aerial Survey

Our use of UAVs for aerial survey allows us to map up to 5,000 acres per day at a resolution of tens of millions of data points per acre. SOA processes data and delivers a centimeter-accurate 2-D and 3-D snapshot of existing conditions for topography, hydrology, or planning purposes.

PE-Stamped Plan Sets

Our Professional Engineers combine their design expertise with SOA’s top-notch data accuracy to deliver value-engineered plan sets that are cost-effective, eliminate the need for rework, reduce risk, and accelerate your project through the planning stage.


Quick Turnaround

SOA prides itself on delivering client value in days, not weeks. We can mobilize and initiate field operations within 5 to 7 business days – for almost any site, under almost any condition. Shortly after, we deliver your completed technical package.

Global Reach

We service 50 US states, 5 countries – and are expanding. SOA’s innovative methodology gives us the flexibility to go where other companies won’t, so we can do the work that other companies can’t – operating on a shoestring to rapidly deliver industry-best data analysis services.
