Office operations for data research, computations, and cartography require personnel with knowledge of which processing software?

• A. AutoCAD
• B. GNSS
• C. GE Surv
• D. NMAX

Answer: (B)

Processing software for data research, computations, and cartography must handle how geographic positions are determined and refined from satellite data. GNSS processing software takes raw satellite observations, applies corrections for orbit, clock errors, atmosphere, and other biases, and computes precise coordinates and baselines. It then outputs geospatial data that can be used directly in maps, GIS analyses, and spatial computations, ensuring accuracy and consistency across datasets.

AutoCAD, while excellent for creating and drafting maps and drawings, does not process GNSS observations to derive coordinates. The other options refer to tools that are not standard GNSS processing platforms, so they don’t fulfill the data-reduction and geospatial computation needs as GNSS processing software does.
