MassDOT is now granting public access to its CORS/Real-Time GPS Network. The MaCORS Network is administered by the Survey Section of the MassDOT Highway Division. Many sectors throughout the Commonwealth that utilize precise positioning applications will benefit from its availability.

The Massachusetts Continuously Operating Reference Station Network (MaCORS) is a system of continuously operating Global Navigation Satellite System (GNSS) reference stations located throughout Massachusetts. It is designed to assist surveying, engineering, and GIS mapping professionals in a variety of static and real-time differential GNSS positioning applications. It is comprised of 18 GNSS base stations located in MassDOT maintenance facilities throughout Massachusetts which are approximately 50 km apart.
Positional information can be obtained from this network through the post-processing of raw static GNSS data downloaded from this website, or in real-time through the use of correction data broadcast via the internet. Depending on equipment and procedures, MaCORS can provide users the ability to achieve 1-3 centimeter positioning for surveying applications or sub-meter positioning for GIS mapping applications.
The MassDOT Survey Office is responsible for the maintenance of the horizontal and vertical network of geodetic survey control stations throughout Massachusetts; MaCORS serves to enhance this network.
