Places
Find Settlements Within a Radius
Click the map to set the centre, choose 10, 25, 50 or 100 km, and search. Every matching settlement comes back as a sortable table and as pins on the map, with its name, type, population and distance from the centre.
Search Inside a Drawn Shape
When a circle is the wrong shape for the job, draw a polygon with the Draw tools and press Use drawn shape to search inside that outline instead of a radius.
Filter by Settlement Size
Narrow the list to cities only, widen it to towns and cities, or include every settlement down to villages. Change a filter after a search and the panel offers to re-run it against the same area.
Population and Exports
Results come from OpenStreetMap, which has no population figure for roughly three quarters of places — those rows show a dash rather than an estimate, so an unknown population never reads as a small one. Signed-in users can download the list as CSV or GeoJSON.
- List cities, towns and villages within 10–100 km
- Or search inside a polygon you have drawn
- Filter to cities, towns & cities, or all settlements
- See name, type, population and distance from the centre
- Results are drawn on the map as pins
- Export the list as CSV or GeoJSON
Tag Zones
Tag Points by the Area They Fall In
Pick a layer of points and a layer of areas, then tag. Every point that lands inside a shape gets that shape's name written into its properties, so it shows up in the attribute table and travels with the point into any export. The areas can be an uploaded file, shapes you drew, or buffers.
Choose the Label Column
Any attribute column on the boundary layer can supply the label — a NAME column on a territories file, for example. Drawn shapes and buffers carry no attributes, so they fall back to a shape number.
Read the Summary and Export
After a run you get a points-per-zone breakdown, including how many points fell outside every shape. A point sitting inside two overlapping zones is counted in both, so the rows can add up to more than the total. Download the tagged points as CSV, and tick Keep a copy first if you want the untagged original kept alongside. The whole run can be undone.
- Tag points with the zone they fall inside
- Use uploaded, drawn or buffered layers as the zones
- Pick which boundary column supplies the label
- See a points-per-zone summary, plus points outside every zone
- Keep a copy of the original, untagged layer
- Download the tagged points as CSV
- Undo a tagging run
File Conversion
Convert Between Geospatial Formats
Upload a file and pick one or more output formats. The tool detects the input type automatically. Shapefile (.zip), GeoJSON, KML, GeoPackage, FlatGeobuf and SQLite all work as both input and output; CSV and GML are available as output formats only. GPX and CSV are not currently accepted as inputs.
Reproject Coordinates (CRS / EPSG)
Change the coordinate reference system of your data during conversion. Set a source EPSG code and a target EPSG code to reproject geometries — useful when moving between WGS84 (EPSG:4326) and projected national grids.
Convert Several Formats at Once
Tick multiple output formats for a single upload and the tool produces each one in a single run. Results are available from the Conversion Results page when processing finishes.
- Convert between Shapefile (.zip), GeoJSON and KML
- Import and export GeoPackage, FlatGeobuf and SQLite
- Export to CSV and GML (output formats only)
- Reproject coordinates between CRS / EPSG systems
- Convert to several output formats in one run
- Download converted files from Conversion Results
CSV Bulk Run
Run an Analysis Across Many Rows
Upload a CSV with one location per row and pick an operation. The tool runs your chosen analysis — location hierarchy, distance to border, distance to coastline, or point-to-point — against every row in a single batch and returns a downloadable results table.
Prepare Your CSV
Download a ready-made template to get the columns right. Hierarchy, coastline, and border runs need SourceLatitude and SourceLongitude (a Location column is optional). Point-to-point runs also need DestinationLatitude and DestinationLongitude for each source pair.
Pick the Operation
Choose Location Hierarchy to get the administrative breakdown of each point, Distance to Border or Distance to Coastline to measure proximity, or Point-to-point to measure the distance between each source and destination pair.
- Run hierarchy, border, coastline or point-to-point in bulk
- Process many coordinates from a single CSV upload
- Download single-point and point-to-point CSV templates
- Map your own columns to source and destination points
- Get all results back as a downloadable table

- See the compass-point abbreviation alongside the degree reading
Add Data to the Map
Open a File on the Map
Drop a .geojson, .json, .kml or .gpx file onto the drop zone, or click it to browse. The file is read in your browser and drawn immediately, and the map zooms to fit what it contains. Other formats — Shapefile, GeoPackage, FlatGeobuf and the rest — need the Files converter first; this panel takes GeoJSON, KML and GPX only.
How Big a File Can Open
Free accounts open files up to 100 MB and paid plans up to 300 MB. Nothing is sent anywhere, so the cap is there to protect your browser tab rather than a server — for anything larger, the Files converter runs server-side and handles far more.
Individually Selectable Features
A file holding a modest number of shapes is split into separately selectable pieces, so you can click one shape, zoom to it, rename or recolour it, and open its properties in the attribute table. That limit is a shape count set by your plan — 300 on a free account and 10,000 on any paid plan — and is entirely separate from the megabyte size limit above. Past it the file still draws in full, but as one combined layer in a single colour: individual shapes can't be clicked, coloured by column or opened in the attribute table, which keeps the map responsive.
- Open GeoJSON, KML and GPX files on the map
- Files are read in your browser and never uploaded
- Up to 100 MB on a free account, 300 MB on a paid plan
- Up to 300 shapes selectable individually, 10,000 on a paid plan
- Rename, recolour, zoom to or remove a single feature
- Open the attribute table to read and edit properties
Layers
One Place for Every Layer
Whatever you add to the map — measurements, drawn shapes, uploaded data, buffers and analysis results — shows up here as a layer. Each row lets you show or hide it, jump the map to it, rename it, or remove it.
Recolor and Export
Give drawn, uploaded and buffer layers a custom color so they stand out, and export any layer's geometry as a GeoJSON file. Use the header Copy/Download to grab the whole map as a single GeoJSON in one go.
- Show or hide any layer with one click
- Recolor drawn, uploaded and buffer layers
- Rename, zoom to, or delete a layer
- Export a single layer as GeoJSON
- Copy or download the whole map as GeoJSON
Draw
Draw Shapes on the Map
Pick a shape — marker, line, polygon, rectangle, circle or text — and click on the map to place it. Everything you draw becomes a layer you can manage from the Layers panel.
Style and Edit
Choose a color, stroke width and fill opacity for new shapes and the last shape you drew. Switch to Edit to reshape existing geometry, or Delete to remove it.
- Draw markers, lines, polygons, rectangles and circles
- Add text labels anywhere on the map
- Set color, stroke width and fill opacity
- Edit or delete shapes after drawing
- Every shape becomes a manageable layer
Add Coords
Add Points by Typing Coordinates
Enter a latitude and longitude pair, give it a name if you want one, and it lands on the map. Points gather into a single typed-points layer you can recolour, export or delete from the Layers panel like anything else on the map.
Build a Shape Corner by Corner
Switch to Build a shape and enter each corner in turn. Once you have at least three, close the shape and it becomes a polygon layer. Any corner can be removed from the list before you close it.
Formats It Understands
Decimal (52.2297, 21.0122), DMS (50°03'53"N 19°56'42"E) and degrees with decimal minutes are all accepted, and hemisphere letters may come first or last. The comma separates latitude from longitude. The panel echoes back the decimal value it read before you commit it, so a mistyped DMS entry is visible before it reaches the map.
- Add points by typing latitude and longitude
- Build a polygon corner by corner (three corners minimum)
- Accepts decimal, DMS and degrees-and-decimal-minutes
- See the decimal value understood before you add it
- Name any point or finished shape
- Typed points and shapes are layers like everything else
Buffer
Create a Buffer Zone
Pick a layer to buffer, set a distance in meters or kilometers, and create a zone that wraps the shape at that distance. Useful for catchment areas, setbacks, exclusion zones and proximity analysis.
Manage Your Buffers
Each buffer is a layer you can rename, recolor, zoom to or delete. The original distance stays in the buffer's subtitle so you always know what it measures.
- Buffer any drawn, uploaded or measured layer
- Set the distance in meters or kilometers
- Recolor buffers from a built-in palette
- Rename, zoom to, or delete a buffer
- Buffers are layers like everything else
