JOA Surveys, LLC (JOA) provides support for a variety of hydrographic services. Our specialty is water-level measurement and tidal datum determination. Water-levels are an integral part of shoreline mapping, nautical charting, tidal determination and bathymetric surveys.
We install, operate and maintain zoning, tertiary, secondary and primary water-level stations. We have online tools for plotting, QC’n and downloading data transmitted via satellite telemetry. This database can be used by our clients for flight planning on shoreline mapping projects and a data portal for field processing. This has proven to be an invaluable tool for us to monitor data quality at remote stations.
