Geovara — Free Online GeoJSON Editor, Shapefile Viewer & Map Drawing Suite

Professional Geospatial Data Editing & Analysis Platform

Geovara is a free, modern web-based GIS platform and GeoJSON editor designed for geospatial engineers, developers, urban planners, and GIS analysts. Draw, edit, convert, validate, and analyze geographic data across standard 2D cartographic projections and photorealistic 3D globe views — 100% in-browser with zero registration or installation required.

Automatic Shapefile (SHP/ZIP) Import & Reprojection

Import Shapefile .zip archives seamlessly. Geovara automatically parses SHP, DBF, PRJ, and CPG components. When projected coordinate reference systems (such as UTM Zone 48S / EPSG:32748) are detected, Geovara leverages Proj4js to automatically reproject geometry coordinates into standard WGS 84 (EPSG:4326), guaranteeing instant and accurate visualization on the map.

Comprehensive Multi-Format Spatial Importer & Exporter

Convert and edit across leading geospatial file formats: GeoJSON, TopoJSON, Shapefile (.zip), Comma-Separated Values (CSV with latitude/longitude or WKT geometries), Well-Known Text (WKT), Keyhole Markup Language (KML), and GPS Exchange Format (GPX).

Interactive Geometry Drawing & Knife Splitting Tool

Digitize spatial features with high-precision tools: Point, LineString, Polygon, Rectangle, and Circle. Utilize the Knife / Slice tool to split polygons into separate geometries with automatic attribute preservation. Benefit from magnetic vertex snapping, live vertex editing, and complete undo/redo action history (Ctrl+Z / Ctrl+Y).

Advanced Spatial Operations & Analysis

Execute powerful geometric algorithms directly in the browser powered by Turf.js: Buffer generation with custom distance radius, Convex Hull generation, Polygon Dissolve (merging overlapping boundaries), Bounding Box calculation, Centroid extraction, and Douglas-Peucker geometry simplification.

Real-time Geodesic Measurement

Calculate geodesic distances and polygon surface areas in real-time. Measurement labels are dynamically clamped and formatted in metric units (meters, kilometers, m², and km²).

Photorealistic 3D Globe with Atmosphere & Cartographic Labels

Experience 3D geospatial exploration powered by CesiumJS. Features include realistic atmospheric scattering, dynamic solar lighting, star constellations, synchronized basemap imagery, and automatic ground-clamped 3D vector rendering with place name labels.

0ms Deterministic RFC 7946 Validator

Validate GeoJSON syntax, geometry types, coordinate bounds, and winding order rules in 0ms latency with zero AI quota consumption. Get instant actionable error indicators with exact line numbers in the Monaco code editor.

AI-Powered Spatial Assistant

Interact with your geospatial data using natural language commands powered by Google Gemini AI. Ask the assistant to fly to geographic coordinates, perform spatial buffers, filter feature attributes, or query spatial relationships.

Privacy-First Stateless Architecture

Geovara processes all spatial operations locally on your machine using in-memory Web Workers. Share full map workspaces instantly via URL hashes compressed with LZW algorithms — no data is stored on remote servers.

Frequently Asked Questions

What is Geovara and how does it compare to geojson.io?

Geovara is a modern, high-performance alternative to geojson.io. While retaining the simplicity of instant browser-based GeoJSON editing, Geovara introduces advanced capabilities including automatic Shapefile reprojection, polygon knife slicing, photorealistic 3D globe visualization, multi-format conversion (CSV, WKT, KML, TopoJSON), and AI spatial assistance.

How do I convert Shapefile to GeoJSON online for free?

Simply drag and drop your Shapefile .zip archive into Geovara. The platform automatically extracts the files, detects the coordinate reference system from the .prj file, reprojects projected coordinates (like UTM) to WGS84, and outputs valid GeoJSON in the editor for instant export.

How do I split or cut polygons on a map?

Activate the Knife (Slice) tool from the toolbar and draw a cut-line across any polygon on the map. Geovara computes the intersection and splits the polygon into distinct feature parts while retaining all property attributes.

Can I import CSV files with coordinates or WKT?

Yes, Geovara automatically parses CSV files containing latitude/longitude columns (such as lat, lon, latitude, longitude, Y, X) or Well-Known Text (WKT) geometry columns into interactive map features.

Is my data private and secure in Geovara?

Yes. Geovara operates entirely client-side. Your geospatial files, coordinates, and attribute tables are never uploaded to or stored on external database servers.
