GPS and GNSS for GIS Professionals

A coordinate is only useful when you know how accurate it is, what reference system it belongs to, and whether you can trust it.GPS and GNSS for GIS Professionals takes you beyond simply accepting the blue dot on a screen. It builds the practical GNSS knowledge you need to collect, evaluate, transform, document, and integrate positional data with greater confidence from field capture to finished GIS. Inside, you'll learn how to: - Understand GPS, GLONASS, Galileo, BeiDou, satellite signals, geometry, and positioning errors- Work confidently with datums, ellipsoids, coordinate reference systems, EPSG codes, and map projections- Recognize datum shifts and avoid costly coordinate-system mismatches- Compare autonomous GNSS, differential correction, RTK, network RTK, PPP, and PPP-RTK- Match recreational, mapping-grade, sub-meter, and survey-grade equipment to project requirements- Plan more defensible GNSS field-data collection and quality-control procedures- Assess horizontal and vertical accuracy and understand commonly used positional-accuracy standards- Apply post-processing and differential-correction workflows- Move corrected GNSS data into ArcGIS Pro, QGIS, mobile GIS, and field-to-office workflows- Understand GNSS applications in drone mapping, spatial-data infrastructure, metadata, and emerging positioning technologyWritten for GIS analysts, technicians, field crews, program managers, students, and professionals in surveying-adjacent, engineering, utilities, public works, and natural-resource roles, this book connects satellite positioning with the GIS decisions professionals make every day.Stop treating positional accuracy as a black box.
