National Surveyors Week 

Surveyors Week falls on the 3rd full week of March each year.  This time of recognition for the professional of surveying and those who practice it is celebrated on a Nation Level and on a State Level.  At the state level, Pennsylvania requests a Proclamation from the Governor every year celebrating Surveyors.

PSLS Reaching New Heights

In an effort to improve the geoid and implement the next iteration of our vertical datum, PSLS is seeking volunteers to occupy First and Second Order Bench Marks with dual-frequency GPS receivers for 4.5 hours.  This data will be submitted to OPUS and the solutions published so NGS can use them to refine the current geoid and to develop the upcoming vertical datum known as GRAV-D.  PSLS is working to make the process as simple as possible to accommodate those familiar with OPUS and those that are not.
