geoBoundaries API

healthy 3,933 Subscribers

Open administrative boundaries as an API, powered by geoBoundaries — the open database of political administrative boundaries built by the William & Mary geoLab. For more than 200 countries and every administrative level — ADM0 (national), ADM1 (states, provinces or regions), ADM2 (counties or districts) and on down to ADM4/ADM5 local units — get the boundary's metadata (official name, the source agency that produced it, the data licence, the year represented, the number of administrative units and the mean vertex count) together with direct download links to the geometry in full-resolution GeoJSON, a simplified GeoJSON, TopoJSON and a ZIP bundle; list every administrative level available for a country with its unit count and download link; and browse the full catalogue of countries that have boundaries. The geometry itself is delivered as standard GeoJSON/TopoJSON files at the returned URLs, ready to drop into Leaflet, Mapbox, QGIS, deck.gl or any GIS pipeline. Ideal for mapping and visualisation, choropleths, spatial joins, geofencing, election and census cartography and location analytics. ISO codes are 3-letter (DEU, USA, BRA); administrative levels are ADM0 to ADM5. Data from the geoBoundaries project (CC-BY 4.0).

Coordinate Systems API

Map projections and coordinate reference systems as an API — the EPSG dataset made queryable. Every CRS, from geographic systems like WGS 84 (the GPS standard, EPSG 4326) to projected ones like Web Mercator (3857), the UTM zones and national grids, has an EPSG code. Search the dataset by name to find the code you need, then resolve any code to its full definition: name, kind (geographic, projected, …), area of use, scope, and — most usefully — the ready-to-paste PROJ.4 string and WKT definition that GIS libraries (GDAL, PROJ, PostGIS, Leaflet, OpenLayers, QGIS, GeoPandas) consume directly. Search comes from the official EPSG Registry maintained by IOGP; the PROJ.4/WKT exports come from epsg.io. A geodesy / coordinate-reference-system resource — distinct from geocoding (addresses to coordinates), geohashing and administrative-boundary APIs. Ideal for GIS, mapping, surveying, remote-sensing and spatial-data applications.

Climate API

Classify any location's climate with the Köppen-Geiger system — the standard used across geography, ecology, agriculture and architecture. Provide a location's twelve monthly mean temperatures and precipitation totals and get back its climate code (for example Cfb or BWh), the climate group and full name, a description, and a block of derived statistics (annual mean temperature, annual precipitation, warmest and coldest month, driest month, months above 10 °C, summer-precipitation share and the aridity threshold). The hemisphere is auto-detected from the temperature curve, or you can set it explicitly. A reference endpoint returns all thirty Köppen-Geiger codes with names, groups, descriptions and example cities. Every endpoint accepts input via the query string or the request body and returns lean JSON. Pure server-side computation (no third-party upstream), so responses are instant and always available. Ideal for EdTech and geography tools, AgTech and crop-suitability apps, architecture and GIS pipelines.

Elevation API

Terrain elevation in metres above sea level for any coordinate — a single point or a batch of up to 50 points for route and grid profiles. Ideal for hiking and outdoor apps, mapping, drone flight planning, solar siting, flood and line-of-sight analysis.

Geohash API

Work with geohashes through a fast, fully-local API. Encode a latitude/longitude pair into a geohash at any precision (1–12), decode a geohash back to its centre coordinates with the exact bounding box and error margins, list the eight neighbouring geohash cells (north, north-east, east and so on), or get the bounding box, centre and dimensions of a cell. Geohashes turn coordinates into short sortable strings that are perfect for spatial indexing, proximity grouping and map tiling. Pure server-side computation with no third-party upstream, so responses are instant and the service is always available. Ideal for geospatial indexing and search, proximity and nearby queries, map tiles and clustering, IoT and fleet tracking, and location bucketing in databases.
