21 tools

• calculate_distance

  Exact 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…

• check_spatial_relationship

  Ground-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_operation

  Compute a buffer (shape-preserving, metres), geodesic area or length, centroid or convex hull. Returns the resulting geometry as GeoJSON with its measurements and units.

• geocode

  Find 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_geocode

  Find the address or place at a coordinate (OpenStreetMap Nominatim).

• get_elevation

  Ground elevation in metres (Copernicus GLO-30, Open Elevation fallback), with its vertical datum and accuracy.

• route

  Driving route between two points (OSRM over OpenStreetMap): line geometry, distance in metres and duration in seconds.

• get_weather

  Current weather and a daily forecast for a point (Open-Meteo, no key needed).

• get_air_quality

  Latest 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_fires

  Satellite active-fire detections near a point (NASA FIRMS; the server needs a FIRMS_MAP_KEY).

• isochrone

  Where 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_matrix

  Network travel time (minutes) and distance (metres) from each origin to each destination. Note: points here are [latitude, longitude] pairs.

• overture_features

  Open 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…

• transform_coordinates

  Convert 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…

• convert_height

  Convert 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…

• sun_position

  The 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_times

  Sunrise, 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_horizon

  The 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…

• line_of_sight

  Whether 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_report

  A 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_site

  Rank 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.
