GPS Inspector

GPS Inspector is a geospatial QA tool designed for GIS analysts, surveyors, logistics planners, and field teams who need to validate coordinates, verify data quality, and accelerate QA workflows. It centers on coordinate accuracy, datum awareness, and transparent calculations. Users supply coordinates in common formats, select a reference datum, and specify units. The tool then applies established geodetic methods to produce interpretable results without requiring scripting, enabling faster data vetting and auditability across projects.
Conceptually, the engine accepts two points (A and B) or a single point for boundary checks. It validates input ranges, normalizes formats, and computes great-circle distance and initial bearing using widely adopted formulas. When a second point is provided, the system also returns forward/back azimuth, delta latitude/longitude, and a simple accuracy score. All outputs come with units and clear numeric boundaries to support threshold-based decision making in field operations and data merges.
Unique value includes datum-aware validation, optional altitude context, and deterministic results suitable for reproducible GIS workflows. The tool flags outliers when distance or bearing deviate beyond configured thresholds, and it refuses to produce ambiguous results for invalid coordinates. It also supports export-ready data structures and CSV/JSON compatibility to integrate into ETL pipelines, quality dashboards, and inventory systems.
Typical use cases include QA of GPS logs from field surveys, asset-tracking validation, data merges across disparate sources, and disaster-response mapping where rapid coordinate validation is essential.
