About Us

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 a vast knowledge and keen understanding of the land throughout Sonoma, Marin, Napa, Lake and Mendocino Counties.

Land Surveying Services

With knowledge and records of over 4,000 land parcels, we know original survey lines and monuments used by previous surveyors and we have a great rapport and history with other 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) equipment. Our Geographic Information System (GIS) is so powerful it can track your land in layers; from where you buried your irrigation systems to the type of vines in a vineyard and can even include a report of the yield per field.

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 truly are "Mapping a Better World."
