WKT Viewer

The WKT Viewer is a focused parser and validator for Well-Known Text strings used in GIS workflows. It accepts a WKT string and returns the inferred geometry type, coordinate arrays, and a computed bounding box. If an SRID is provided, it is stored with the results but no coordinate transformation is performed, keeping outputs faithful to the input frame of reference. Conceptually, the tool operates as a lexical parser that builds a lightweight geometry model in memory and derives simple metrics like area for POLYGONs and length for LINESTRINGs. This supports data ingestion checks, QA verification, and quick geometry previews without requiring a full GIS stack. The key differentiator is speed and determinism: instant feedback on syntax, type, and basic metrics, suitable for integration into data pipelines and automated validation steps. Use cases include validating user-submitted WKT in data-entry portals, inspecting geometry samples in ETL jobs, and pre-validating data before storage. Core features include syntax validation, geometry type inference, coordinate extraction, and optional metric calculations. Outputs are designed for easy consumption by downstream processes, with a JSON structure containing validity, type, coordinates, and metrics. The tool avoids rendering or styling tasks and stays focused on domain logic and data integrity.

Examples: parsing "POINT(30 10)" yields type POINT, coordinates [30,10], valid=true; parsing with SRID="SRID=4326;LINESTRING(30 10,40 40)" yields srid 4326, type LINESTRING, coordinates [[30,10],[40,40]], length computed. This tool is valuable for GIS developers, data engineers, and QA staff who require reliable, fast, and portable WKT analysis.
