Coordinate Converter for QGIS

About This Tool

The Coordinate Converter for QGIS is a domain-focused tool designed to transform point coordinates between coordinate reference systems (CRS) to support interoperable GIS data. It accepts source CRS identifiers (EPSG codes or PROJ/WKT strings), a target CRS, and coordinate inputs, and returns coordinates in the destination system. This enables accurate data exchange, QA checks, and ready export for analysis, mapping, and cataloging.
Under the hood, the tool uses a PROJ-based transformation engine that adheres to EPSG registry conventions. It handles 2D and 3D coordinates, respects axis-order expectations, and applies necessary datum shifts when defined. Users may supply a single coordinate pair or a batch of pairs; the engine computes precise results and reports them in the target CRS units.
Who benefits includes geospatial analysts, surveyors, urban planners, and data engineers integrating GIS layers into workflows. The tool reduces manual calculations, minimizes transcription errors, and accelerates data interoperability across project stages from field collection to GIS analysis. Common use cases include converting WGS84 data to local projected systems (UTM zones), aligning legacy datasets, and preparing coordinates for asset inventories or environmental modelling.
Unique value lies in its standards-based approach, wide CRS support, and batch processing readiness. Core features include 2D/3D transformation, EPSG and PROJ string inputs, configurable output precision, and clear numeric results for downstream pipelines. By encapsulating CRS logic in a single, auditable module, the tool streamlines GIS data preparation for reliable mapping, reporting, and regulatory compliance.
