Fast, browser-based geo utilities. Drop in your files, get results instantly. No complex software, no setup required.
Each tool is a single page — no complex setup, no dependencies on external servers.
The master converter. Transform Shapefiles, GeoPackage, GDB, KML, and more into valid GeoJSON. Multi-layer support and coordinate reprojection included.
↗Combine two or more GeoJSON FeatureCollections into a single merged file. Validates each file, shows feature counts, and generates a ready-to-download result.
↗Dissolve internal borders of polygons to create a single outline. Combine states into a country or counties into a region.
↗Explore a GeoJSON file's structure — feature types, property keys, bounding box, and coordinate counts. No map required.
Convert a CSV with latitude/longitude columns into a valid GeoJSON FeatureCollection. Map any column to a point property.
Reduce file size by simplifying polygon and line geometries using Ramer–Douglas–Peucker. Adjust tolerance visually.
Strip unwanted property keys from every feature in a GeoJSON file. Keep only what you need and slim down bloated exports.
Convert GeoJSON between coordinate reference systems — e.g. OSGB36/BNG to WGS84 — entirely in the browser using proj4js.
Every tool runs directly in the browser. No round-trips, no loading screens. Drop a file, get a result.
Each tool is focused and self-contained. No sprawling dashboards, no learning curve — just the utility you need, right now.
Designed for analysts, developers, and data journalists who work with geographic data and need quick, trustworthy utilities.
We use the File API, Blob URLs, and modern JavaScript — no heavy dependencies for most tools.

Professional interactive mapping solutions for the world's most popular CMS. No complexity, just results.
Trusted third-party tools that pair well with getlong.lat for editing, inspecting, and testing GeoJSON files.
The gold standard for simplifying and editing geographic data in the browser. Import GeoJSON, Shapefile, TopoJSON and more — then simplify, filter, clip, dissolve, and export. Indispensable for reducing file sizes without losing shape quality.
↗Paste or upload a GeoJSON file and instantly render it on an interactive globe. A quick sanity-check for coordinates, geometry validity, and visual layout — useful before embedding data into a map or project.
