validate_geojsonCheck whether a GeoJSON file/string is valid — catches broken geometry, malformed structure, self-intersections, and out-of-range coordinates before you try to use the file elsewhere (e.g. "is this GeoJSON valid", "why won't my GeoJSON load", "lint my GeoJSON", "check topology e…
geojson_to_csvConvert GeoJSON to CSV/spreadsheet — one row per feature, properties as columns, geometry flattened into a column (e.g. "turn this GeoJSON into Excel/CSV", "I need a spreadsheet from these map features", "export GeoJSON as a table"). Returns the CSV as plain text.
count_featuresCount features in an ArcGIS FeatureServer layer, optionally filtered by a WHERE clause. service_url: full layer URL ending in /FeatureServer/<n>. token: only for private layers. Returns JSON: {"ok": true, "count": ..., "name": ..., "geometry": ...}.

check_field_typesInspect the field schema of an ArcGIS FeatureServer layer. Returns JSON: {layer_name, geometry_type, fields:[{name, alias, type, length, nullable, has_domain}]} — useful before importing/mapping data.
check_service_healthCheck whether an ArcGIS FeatureServer layer is reachable and responsive. Returns JSON: {ok, ms (latency), name, geometry_type, field_count, record_count, capabilities, max_record_count}.
rest_exploreList the layers and tables of an ArcGIS FeatureServer/MapServer root. Point at a service root to enumerate its layers/tables, or at a single layer URL to describe it. Returns JSON: {is_server, layers:[{id, name, type}]}.
compare_schemasCompare the field schemas of two ArcGIS FeatureServer layers. Returns JSON diff: {added, removed, changed:[{field, diffs}], same, geometry_match, identical} — useful for QA before an import or migration.
shapefile_to_geojsonConvert a Shapefile ZIP (base64-encoded .zip with .shp/.dbf/.shx[/.prj]) to a GeoJSON FeatureCollection. Reprojects to WGS84 if a .prj says otherwise. Returns JSON: {geojson: {...}, reprojection_notice: str|null}.
kml_to_geojsonConvert Google Earth / Google My Maps KML (2.0–2.2) to GeoJSON — the common request when someone exported a map from Google Earth or Google My Maps and needs it in a format other GIS tools/APIs accept (e.g. "convert my Google Earth file to GeoJSON", "KML to GeoJSON"). Returns th…
gpx_to_geojsonConvert a GPS track/route file (GPX — from Garmin, Strava exports, hiking/cycling apps, waypoints) to GeoJSON (e.g. "convert my GPS track to GeoJSON", "GPX to GeoJSON", "import my Strava route"). Returns the GeoJSON FeatureCollection as a JSON string.

geojson_to_mapinfo_tabConvert GeoJSON to a MapInfo TAB file set, ready for MapInfo Pro. TAB is a multi-sidecar-file format (.tab/.dat/.id/.map) and single geometry type per file, like Shapefile — always returned as a zip, mixed point/line/polygon input is split into one .tab set per category. Returns…
query_featuresFetch actual feature records (attributes + geometry) from a FeatureServer layer. Free preview capped at 50 records (WHERE filter + chosen fields). Returns JSON: {returned, total, truncated, geojson, note}. Full unlimited export is a paid operation.
query_statisticsServer-side aggregate stats on a numeric field of a FeatureServer layer. No records fetched — AGOL computes sum/avg/min/max/count (also stddev/var). Optional WHERE filter and group_by field. Returns JSON: {field, results:[...]}. Cheap way to answer "what's the average/total of f…
geometry_statsCompute area (m²/km²), length (m/km), vertex count, centroid and bbox of GeoJSON. Metric measurements use an equal-area projection so area/length are real metres.
reproject_geojsonChange a GeoJSON's coordinate reference system (CRS/projection) — e.g. "reproject to Web Mercator", "convert WGS84 to UTM", "my coordinates are in the wrong CRS", "EPSG:4326 to EPSG:3857". Reprojects every geometry type between any two EPSG codes.
simplify_geometryReduce the number of vertices in GeoJSON geometry (Douglas-Peucker algorithm) — e.g. "simplify this polygon", "this shape has too many points", "reduce vertex count for faster rendering". Tolerance in degrees; lower = more detail kept.
reduce_precisionRound every coordinate to N decimal places to shrink a GeoJSON file's size — e.g. "my GeoJSON file is too big", "reduce coordinate precision", "strip excess decimal places". 6 decimals ≈ 11cm precision, plenty for most mapping use cases.
csv_to_geojsonConvert a CSV/spreadsheet with lat/lon (or X/Y) columns to GeoJSON — auto-detects the coordinate columns (e.g. "map this spreadsheet", "CSV with lat/lon to GeoJSON", "turn my Excel export into map points"). Returns a GeoJSON FeatureCollection as a JSON string.

csv_to_gpxConvert a CSV with latitude/longitude columns directly to GPX waypoints (2026-09-03) — e.g. "these coordinates to a GPX for my GPS". Column names are auto-detected (lat/latitude/y, lon/lng/longitude/x).
gpx_to_csvConvert a GPS track file (GPX) directly to CSV (2026-09-03) — waypoints get LATITUDE/LONGITUDE columns, tracks/routes get a GEOMETRY_WKT column instead.
wkt_to_geojsonConvert a WKT (Well-Known Text) geometry string — the format PostGIS/SQL geometry columns print by default — to GeoJSON (e.g. "this came from a PostGIS query", "WKT to GeoJSON", "parse this POLYGON(...) string").
geojson_to_wktConvert a GeoJSON geometry (or a Feature's geometry) to WKT — the format needed to insert geometry into PostGIS/SQL (e.g. "I need this for a PostGIS INSERT", "GeoJSON to WKT", "geometry as WKT string").
dxf_to_geojsonConvert an AutoCAD DXF file's contents to GeoJSON — e.g. "convert this DXF to GeoJSON", "AutoCAD drawing to GIS format", "DXF export from Civil 3D to GeoJSON", "extract only the UTILITIES layer from this DXF". POINT/LINE/LWPOLYLINE/POLYLINE/ARC/CIRCLE/ELLIPSE/SPLINE/HATCH/MPOLYG…
geojson_to_dxfConvert GeoJSON to an AutoCAD DXF file — e.g. "export this GeoJSON to DXF for AutoCAD", "GIS data to CAD format", "convert to .dxf for Civil 3D". Points become DXF POINT entities; lines and polygon rings become LWPOLYLINE entities. A feature's properties.layer (if present) is wr…
list_dxf_layersList the distinct DXF layer names used in a drawing — e.g. "what layers does this DXF have", "list layers before I extract one". Real CAD exports organize entities into named layers (BOUNDARY, UTILITIES, TEXT, ...); use the result with dxf_to_geojson's `layer` param to pull out…
georeference_dxfReproject a DXF drawn in a local/arbitrary CAD coordinate system into real-world coordinates — e.g. "this DXF isn't in real coordinates, fix it", "georeference this site plan", "I know 2 points on this drawing's real location, convert the rest". Give exactly 2 control points as…
dxf_to_pdf_reportPAID (150 credits) — render a DXF drawing to a one-page PDF site-plan report (vector plot + entity-type breakdown + layer list, base64- encoded PDF) — e.g. "make a PDF of this site plan", "DXF to PDF report". No basemap (DXF coordinates are usually local drawing units, not real…

share_mapPublish a GeoJSON FeatureCollection as a live, shareable map page on gisgp.com. Returns JSON: {url, expires_at} — url is a public interactive map a human can open in a browser (free links live 30 days). Use it to hand off results of a GIS workflow visually instead of pasting raw…
embed_map_snippetReady-to-paste <iframe> embed code for a live interactive map — thin wrapper around share_map (same live page, same 30-day TTL), for embedding directly in a website/dashboard rather than sharing a link. Returns JSON: {ok, embed_html, url, expires_at}.
buffer_geojsonBuffer every feature by a distance in METRES (negative shrinks). Geodesically accurate at any latitude (each feature is buffered in a local equidistant projection). Returns JSON {ok, distance_m, geojson} where geojson is a FeatureCollection of buffer polygons.
dissolve_geojsonMerge overlapping/adjacent geometries into one (optionally grouped by a property field `by` → one dissolved feature per distinct value). Returns JSON {ok, by, group_count, geojson}.

convex_hull_geojsonDraw the smallest polygon that wraps around all input features (a convex hull) — e.g. "draw a boundary around these points", "find the outer perimeter of my data", "convex hull of these locations". Returns JSON {ok, geojson} — a single polygon.
overlay_geojsonCombine two GeoJSON FeatureCollections with a boolean set operation. op: intersection | difference (a minus b) | symmetric_difference | union. Each side is unioned into one geometry first, then the operation is applied. Returns JSON {ok, op, geojson} — empty geojson means no ove…
spatial_join_geojsonAttach properties from every B feature that satisfies a spatial predicate to each A feature (as a `_matches` list). predicate: intersects | within | contains | touches | crosses | overlaps. Returns JSON {ok, predicate, match_count, geojson}.
nearest_features_geojsonFor each feature in A, find the nearest feature in B by centroid-to- centroid geodesic distance. Attaches `_nearest` properties and `_nearest_distance_m`. Returns JSON {ok, geojson}.
