calculate_distanceExact geodesic distance between two places or geometries on the WGS84 ellipsoid. Use for any "how far" question instead of estimating. For NAMED places pass place_a and place_b; the server geocodes them, so never type coordinates for a place yourself. Use point_a/point_b only fo…
check_spatial_relationshipGround-truth topology: does geometry_a <relationship> geometry_b? Use instead of guessing containment, overlap or adjacency. Invalid geometries (for example self-intersecting polygons) are refused with the reason.
spatial_operationCompute a buffer (shape-preserving, metres), geodesic area or length, centroid or convex hull. Returns the resulting geometry as GeoJSON with its measurements and units.
geocodeFind coordinates for an address or place name (OpenStreetMap Nominatim). Check `geospark.warnings` for ambiguous names (e.g. "Springfield") and ask the user which one they mean, or add a region.
reverse_geocodeFind the address or place at a coordinate (OpenStreetMap Nominatim).
get_elevationGround elevation in metres (Copernicus GLO-30, Open Elevation fallback), with its vertical datum and accuracy.
routeDriving route between two points (OSRM over OpenStreetMap): line geometry, distance in metres and duration in seconds.
get_weatherCurrent weather and a daily forecast for a point (Open-Meteo, no key needed).
get_air_qualityLatest PM2.5, NO2, O3 from the nearest monitoring stations (OpenAQ; the server needs an OPENAQ_API_KEY), with each station's data licence.
get_active_firesSatellite active-fire detections near a point (NASA FIRMS; the server needs a FIRMS_MAP_KEY).
isochroneWhere can you get to from a point within N minutes on foot, by bike or by car? Returns one polygon per contour with its geodesic area (Valhalla over OpenStreetMap).
travel_time_matrixNetwork travel time (minutes) and distance (metres) from each origin to each destination. Note: points here are [latitude, longitude] pairs.
overture_featuresOpen global map data from Overture Maps, no API key: points of interest (with categories), building footprints (height, floors, geodesic footprint area), road and path segments (geodesic length), or `divisions`, the administrative areas containing the point (country, region, cit…
transform_coordinatesConvert coordinates between CRSs as the official transformation does: GDA94 to GDA2020, MGA zones, British National Grid (OSTN15), NAD27 to NAD83 (NADCON), ITRF at an epoch, and any other EPSG pair. Uses national grids (downloaded once), refuses PROJ's ballpark approximations, a…
convert_heightConvert a height between the ellipsoid (GNSS, drones) and a national height datum with the official geoid model: AHD (AUSGeoid2020), ODN (OSGM15), NZVD2016 (NZGeoid2016), NAVD88 (GEOID18), or global EGM2008. Never estimate a geoid separation from memory: it is often tens of metr…
sun_positionThe Sun's apparent elevation and azimuth (from true north) at a place and time, and the shadow a vertical object casts on level ground (NOAA solar position, refraction included).
sun_timesSunrise, solar noon, sunset and day length on a date for a flat horizon; with terrain=True, also the hours of direct sun once hills are taken into account.
terrain_horizonThe skyline the terrain makes around a point: for each azimuth, the elevation angle of the horizon and how far away the blocking terrain is (Copernicus 30 m DEM, Earth curvature and refraction). Use for solar-panel shading, valley sunlight, or what hills hide. ~10-60 s.
line_of_sightWhether A and B can see each other over the terrain (Copernicus 30 m DEM, curvature and refraction), the minimum clearance and where it occurs; with frequency_mhz, the first Fresnel zone clearance of a radio link (60% clear is the usual rule).
location_reportA dossier for a place: address, elevation, weather, and nearby amenities with exact distances, as a GeoJSON map layer listing every data source used. Takes ~10-30 s.
select_siteRank candidate sites in an area by geodesic distance to amenities you want nearby and away from ones to avoid (OpenStreetMap data). Takes ~10-30 s.
