A century of Central Florida surveying
Founded by Joe Johnston in 1920, our firm has helped lay out the roads, communities, and public works that built the region — more than 23,000 completed projects, coast to coast, and counting.
We know this ground firsthand
For more than a hundred years, our field and office teams have measured and mapped Central Florida — from major roadways and planned communities to industrial and municipal projects. That longevity isn't just a number. It's a record of monuments set, plats recorded, and decisions clients could build on.
We pair that firsthand knowledge and long-standing relationships with local governments with current methods and legal requirements, so every survey holds up in the field, at the county, and in the record — coast to coast across the region.
Two offices. One region, coast to coast.
Field crews and mapping staff working across Central Florida — from the Kissimmee headquarters south and central, to the Oviedo office covering Seminole County and the northeast.
