The Carlson Story

Ray Carlson and Associates, Inc. has been surveying and mapping the North Bay since 1976. As a premier land consulting firm located in Santa Rosa, we offer vast knowledge and a keen understanding of the land throughout Sonoma, Marin, Napa, Lake and Mendocino Counties.

With knowledge and records of over 5,000 land parcels, we know original survey lines and monuments used by previous surveyors and we have a great rapport and history with agencies in order to complete your project. At Ray Carlson & Associates, we are always on the leading edge of surveying technology to ensure the highest possible professional service.

Our innovative approach to surveying includes being the first surveying firm in Sonoma County to own Global Positioning Satellite (GPS) surveying equipment. Our Geographic Information System (GIS) can track your land in layers; from where you buried your irrigation, electrical, and phone systems to the type of vines in a vineyard and can even include a report of the yield per field.

Our newest asset for surveying and GIS is a drone (small unmanned aerial vehicle – UAV). With this new technology, we can survey and gather more data than ever before. We are a dedicated team of professionals tuned into the land and the communities upon it. We invite you to make Ray Carlson and Associates your professional choice for all your GIS data management and surveying projects.

We have surveyed or mapped over 5,000 properties all over the North Bay.

Ray Carlson & Associates, Inc. has an ongoing commitment to: provide superior customer service; support our professional, highly trained staff; and produce quality land survey and data management products for our clients through a combination of experience, innovation, technology and honest communication.
