Why GeoUtil? ​

🗺️ Map tools ​

Measure ​

Area Tool ​

Measure the true surface area of any region with spherical accuracy. Draw polygons on the map or upload GeoJSON to calculate areas in square kilometers, square miles, hectares, or acres.

Try Area Tool

Bearing / Azimuth Tool ​

Calculate the compass bearing (azimuth) between two points on Earth. Essential for navigation, mapping, and understanding directional relationships. Shows both forward and reverse bearings.

Try Bearing Tool

Distance Tool ​

Calculate great-circle distances between any two points on Earth using accurate spherical geometry. Perfect for measuring flight paths, shipping routes, or understanding true distances between locations.

Try Distance Tool

Globe Distance Tool ​

Visualize distances on an interactive 3D globe with realistic Earth curvature. Rotate, zoom, and see exactly how great-circle routes look in three dimensions.

Try Globe Distance Tool

Radius Around Point ​

Draw one or more accurate radius circles around any point on the map and see their area and circumference. Useful for service areas, proximity checks, travel planning, and distance buffers in kilometers, miles, meters, or feet.

Points ​

Destination Point Calculator ​

Pick a start point, enter a bearing and a distance in kilometres, miles, nautical miles or metres, and see where you end up. The map draws the great-circle path and shows the destination, the final bearing and the reverse bearing.

Lat Long Finder ​

Click anywhere on the map to get that point's latitude and longitude in every notation: decimal degrees, DMS, DDM, UTM, MGRS, SK-42, UCS-2000, Plus Code, Geohash and Maidenhead, each with a one-click copy button, plus the ground elevation. Search a place or paste coordinates in any of those formats to jump there, or use your current location.

Midpoint Calculator ​

Add two or more places and find the halfway point between them. Two points give the exact great-circle midpoint; three or more give their geographic center. Copy the result as decimal degrees, DMS or MGRS and share the map with a link.

Elevation & routes ​

Elevation Finder ​

Look up the estimated ground elevation for any point on Earth with a simple map click. See coordinates plus height in meters and feet using public terrain data, all processed directly in your browser.

Try Elevation Finder

Elevation Profile ​

Draw a route on the map or drop a GPX, KML or GeoJSON file to see its elevation profile, total ascent and descent, steepest grade and distance, with CSV and GPX export. Terrain is read in your browser.

Try Elevation Profile

GPX Viewer ​

Open a GPX file to see the track, its distance, elevation gain and loss and an interactive elevation profile. Nothing is uploaded.

Try GPX Viewer

Ridgeline Map Generator ​

Turn any mountain range, island or city into a ridgeline poster: stacked elevation lines from public terrain data, with titles, colours and print sizes. Download a PNG, a real vector SVG (with a plotter mode for pen plotters and laser cutters) or a print-ready PDF.

Places ​

Population Within a Radius ​

Find out how many people live within any distance of a point: 10 km around your store, 25 miles around a city, with a breakdown from 1 to 100 km. Estimates come from the 2025 global population grid (GHS-POP, European Commission JRC).

Count People in a Radius

Sunrise & Sunset Times ​

Pick a place to see sunrise, sunset, day length, twilight, golden hour and the time zone of any place on any date, with the sun's direction drawn on the map. Switch between the place's time and your own, and share the link. Everything is calculated in your browser.

Live data ​

Earthquake Map ​

See the latest earthquakes worldwide from the USGS feeds: the past day, week or month. Filter by magnitude or by distance from a place, and download the list as GeoJSON, CSV or KML. There are also earthquake pages for countries and cities.

Open the Earthquake Map

Live Wind Map ​

Watch wind speed and direction move across the globe, from the NOAA GFS weather model. Click anywhere to read the wind at that point in km/h, m/s or knots.

Open the Live Wind Map

Live Weather Map ​

See temperature, rain, cloud cover and pressure worldwide from the NOAA GFS model, and click the map to read the value at any point.

📍 Coordinates ​

Coordinate Converter ​

Paste coordinates in any notation and get them in all the others: Decimal Degrees, DMS, DDM, UTM, MGRS, SK-42 and UCS-2000 Gauss-Krüger, Plus Codes, Geohash and Maidenhead. The format is detected automatically, every result has a copy button, and a map preview shows the points.

Try the Coordinate Converter

Coordinate notations ​

• DMS to decimal and decimal to DMS: switch between degrees-minutes-seconds and lat/lon.
• UTM to lat/long and MGRS to lat/long: decode grid references.
• Plus Code, Geohash and Maidenhead converters.

Datums & projections ​

• SK-42 and UCS-2000 to WGS84: Soviet and Ukrainian map coordinates.
• CRS Converter: transform GeoJSON between 500+ coordinate reference systems (EPSG codes), from WGS84 to Web Mercator, UTM zones, national grids and more. The source CRS is detected from the file's metadata or coordinate ranges.

From files ​

Coordinate Extractor: extract every coordinate from GeoJSON files as CSV (lat, lon columns) for Excel, R, Python or other tools.

🔄 Converters ​

To GeoJSON ​

• CSV to GeoJSON: spreadsheets with latitude/longitude columns become GeoJSON Point features, for plotting addresses, locations or any tabular data.
• GPX to GeoJSON: GPS tracks, routes and waypoints from devices and fitness apps.
• KML to GeoJSON: Google Earth KML files for web mapping libraries, with names, descriptions and other attributes kept.
• Shapefile to GeoJSON: upload the Shapefile ZIP (.shp, .shx, .dbf, .prj) and get standards-compliant GeoJSON for web maps.
• TopoJSON to GeoJSON: back to plain GeoJSON for tools that don't read TopoJSON.

From GeoJSON ​

• GeoJSON to CSV, to GPX, to KML and to Shapefile: a CSV for spreadsheets, GPX for GPS devices and apps, KML for Google Earth, or a zipped Shapefile for ArcGIS and QGIS. Properties are kept, and everything runs in your browser.
• GeoJSON to TopoJSON: compact, topology-preserving files, often 80% smaller, with shared boundaries kept.
• GeoJSON and WKT: convert both ways between GeoJSON and Well-Known Text, including EWKT with SRID codes for databases.

To images ​

GeoJSON to SVG, PNG or JPEG: export your map as vector SVG or raster PNG/JPEG images, with your own colors, sizes and projections, for presentations, reports or web graphics.

🧰 File tools ​

Minify ​

• GeoJSON Minifier: reduce GeoJSON file sizes by 50-80%: remove whitespace, reduce coordinate precision, strip properties and simplify geometry.
• JSON Minifier: remove all whitespace from any JSON file.
• TopoJSON Minifier: make TopoJSON smaller by removing whitespace and unneeded properties; the geometry stays exactly as it was.

Merge ​

• GeoJSON Merger: combine many GeoJSON files into one FeatureCollection, keeping every property and mixed geometry types.
• JSON Merger: combine JSON files into one array or object: configuration files, data exports, API responses.
• Shapefile Merger: combine Shapefile ZIP archives into one GeoJSON file, aligning their attributes.
• TopoJSON Merger: merge TopoJSON topologies with their shared arcs rebuilt.

Split ​

• GeoJSON Splitter: split a large GeoJSON file by a property, one file per country, region or category, downloaded as a ZIP.
• TopoJSON Splitter: split TopoJSON by object or property with valid topology in each file.

Inspect ​

Feature Counter / Stats: GeoJSON statistics at a glance: feature counts, geometry types, coordinate counts, total length and area, bounding box and property coverage, for data validation and quality checks.

🔐 Privacy & Security ​

All GeoUtil tools run entirely in your browser using JavaScript. Your data:

• ✅ Never uploaded to any server
• ✅ Stays on your device at all times
• ✅ Completely private — we can't see what you're working on

Most tools provide live previews so you can verify results before downloading.

💡 Use Cases ​

• GIS Professionals: Convert formats, merge datasets, transform coordinate systems, validate data
• Web Developers: Prepare GeoJSON for web maps, reduce file sizes, convert legacy formats
• Data Analysts: Extract coordinates to CSV, calculate areas, analyze geographic data
• Educators: Demonstrate map projections, explain coordinate systems, visualize distances
• Researchers: Process geographic data without cloud services, maintain data privacy
