Comprehensive GIS Capabilities
The Modern Online GIS Software for Web & Browser GIS
Engineered as a high-performance online GIS tool and large GIS file viewer. Everything runs client-side with zero installation.
View Shapefile Online Without Uploading
True online shapefile viewer with zero registration. Drop zipped Shapefiles (.shp, .dbf, .prj) or standalone .shp files up to 2GB+. Parse and stream geometry directly into WebAssembly with 100% client-side privacy.
Online GeoJSON Editor & Attribute Inspector
Comprehensive online GeoJSON editor and GeoJSON viewer. Inspect feature properties, edit layer symbology colors, adjust stroke widths, filter attribute tables, and export features with sub-millisecond responsiveness.
GeoParquet File Viewer & FlatGeobuf
Next-generation GeoParquet file viewer and FlatGeobuf viewer. Mount Apache Parquet and FlatGeobuf files straight into DuckDB-WASM virtual memory for columnar spatial queries and instant viewport rendering.
Interactive 3D GIS Viewer & WebGL Globe
GPU-accelerated 3D GIS viewer and WebGL GIS viewer. Renders geometries directly on a WebGL 3D globe via Deck.gl GPU vertex buffers, bypassing CPU tiling bottlenecks at 60 FPS.
DuckDB Spatial SQL & In-Browser RTREE
Advanced DuckDB spatial viewer and browser GIS tool. Automatically creates RTREE(geom) spatial indices for sub-millisecond spatial SQL filtering (ST_Intersects) without taxing your device's main thread.
Web GIS & Coordinate Reprojection (Proj4)
Modern browser GIS featuring On-The-Fly (OTF) reprojection using Proj4. Automatically converts projected coordinates (UTM, British National Grid, State Plane) into WGS 84 for seamless globe overlay.
ArcGIS REST Server & Layers Catalog
Explore 222 US County parcel servers across 50 states and Abu Dhabi SDI (216 government layers). Filter by geometry or domain theme (parcels, roads, zoning, environment) and stream layers directly into GeoEditor with one click.
High-Performance Pipeline
How This Browser GIS Software Operates
A look inside the client-side architecture powering our online GIS map editor and GIS data viewer.
Zero-Upload Ingestion
Files are loaded directly into browser Web Workers via Transferable ArrayBuffers, ensuring a true GIS viewer no upload experience.
DuckDB-WASM RTREE
Virtual tables are built in WebAssembly. Spatial indices (USING RTREE) accelerate bounding-box queries for our large GIS file viewer.
On-The-Fly CRS
Projected coordinates in UTM, British National Grid, or State Plane are reprojected to WGS 84 in real time by our web GIS engine.
Deck.gl 3D WebGL
GPU vertex shaders render polygons and points at 60 FPS, making this the most responsive 3D GIS viewer online.
Universal GIS File Viewer
Supported GIS & Geospatial Data Formats
No installation, no plugins, and no file conversion. Our online geospatial data viewer handles all standard spatial files.

Frequently Asked Questions
Online GIS Tool & Viewer FAQ
What is the best free online GIS tool and online shapefile viewer?
GeoEditor is the leading free online GIS tool and online shapefile viewer. Built on Next.js, DuckDB-WASM, and Deck.gl, it lets GIS professionals view, edit, and inspect large Shapefiles, GeoJSON, and GeoParquet files in any modern web browser without installing desktop software.
How does this online GIS map editor view large shapefiles with no upload?
As a true GIS viewer no upload solution, all decompression (via WebAssembly fflate) and spatial indexing take place in sandboxed Web Workers. Your data is mounted directly into a DuckDB-WASM virtual file system on your machine, making it an extraordinarily secure large shapefile viewer for proprietary datasets.
Can I use this as an online GeoJSON editor and GeoJSON viewer?
Yes. You can use it as an online GeoJSON editor and GeoJSON viewer to visualize points, linestrings, and complex polygons. You can customize layer colors, opacity, point radii, and stroke widths, inspect raw attributes in an interactive SQL table, and export binary FlatGeobuf files.
Does this 3D GIS viewer support GeoParquet and live ArcGIS REST services?
Yes. As an advanced 3D GIS viewer and GeoParquet viewer, it connects directly to Apache Parquet files, FlatGeobuf files, and live ArcGIS REST endpoints (FeatureServer and MapServer) without requiring middleware or server proxies.
How do I browse 220+ US County parcel servers and Abu Dhabi Open Data in GeoEditor?
GeoEditor includes an integrated Server Catalog with 222 verified US County ArcGIS REST servers across all 50 states, state DOT portals, USGS hazards feeds, and Abu Dhabi SDI (216 government layers). You can search by county or theme and open any layer directly in the studio with one click.
