DaedalMap Geography Tools (loc_id)

Compare two known loc_ids using selected reference-graph identity and direct relationship evidence. Verified Admin ancestry can prove containment; a typed graph edge can prove only the relation it declares. An explicit negative edge returns no_overlap; a missing edge returns unknown. This tool never reads polygons or computes shape intersections. Use an external identifier bridge before this call when the input is not a loc_id. No payment required.

Convert within one declared scope per call: iso3 is required and names one ISO3 country, GLOBAL, or MARINE. A batch uses one from_system, to_system, and crosswalk_id, with at most 25000 requested result rows. Convert X -> loc_id -> Y; omit to_system to enter the loc_id universe. For admin or city names use from_system admin_boundary with a country_hint inside the declared country. A published direct crosswalk uses one selected artifact; if the system pair has multiple artifacts, supply crosswalk_id from the typed ambiguity error. An exact miss ends on that artifact. Use get_geography when family or scope coverage is unknown. The tools/list access metadata states authored free, account, and paid item allowances; active operator policy may waive payment.

Choose data or geometry to list published pack IDs or family and scope IDs. The response includes a complete catalog download URL. Use get_pack for data or get_geography for geometry. Current catalog: The same geography tools work worldwide across a cataloged baseline of 252 geographic entities, reaching up to Admin 2. Where additional country releases are available, the same calls automatically return deeper administrative tiers or maintained reference families. Additional detail is currently available for Australia, Brazil, Canada, France, Germany, Mexico, United Kingdom, United States.

Inspect one published geometry family across scopes or one scope across families. Returns coverage and known editions from catalog metadata only. Optional year selects the latest admitted edition no later than that year when the selected catalog has an edition index; an unavailable index is reported explicitly.

Look up one known loc_id or a small batch in the selected reference graph. Return its identity and directly recorded loc_id connections, with family, direction, and relationship evidence. Each ID returns at most 50 connections and an explicit has_more flag. This tool does not expand descendants, infer containment, read shapes, search catalogs, or consult external adapters. No payment required.

Inspect one exact data pack ID for its metrics, time coverage, and query metadata before get_data.

Shape lookup for exact existing loc_ids only. The default returns shape availability, centroid, and bounding box; include_polygon=true adds GeoJSON coordinates. Obtain any descendant IDs before this call. Historical geometry is returned first and successors are never substituted automatically. Year selection is not yet supported.

Describe one tool visible on this facade, including its exact contract, or return a bounded workflow overview for one supported topic.

Fast structural column selector: pass bounded named columns to find recognized geography headers or latitude/longitude pairs. It does not infer a country, level, or identifier system, open country indexes, or validate values. If more than one column is plausible, select one; then call identify_reference_system with the selected identifier column and one country_scope. No payment required.

Identify one selected identifier column within one required ISO3 country, GLOBAL, or MARINE scope. Pass bounded strings preserving leading zeros. It checks maintained identifier evidence, not dataset columns or polygons. Ambiguous systems stay unselected until expected.system is supplied. Use identify_dataset_geography first when the column is unknown. No payment required.

Compare one non-wrapping rectangular WGS84 viewport with the published Global administrative spine through Admin 2. Supply its four corners. Returns the best equal-area overlap plus nearby matches at each level and their shares of the viewport and loc_id. Large views may require zooming in. This tool reads no country deep bank.

Second-pass rectangle overlap within one returned shallow administrative loc_id. Routes to that country's one Admin 1-owned exact partition and compares its Admin 1-6 spine. Supply the original four WGS84 corners; broad views may require zooming in.

Second-pass containment only after resolve_point. Supply the original WGS84 coordinate or a bounded point array, one shared shallow_loc_id returned by resolve_point, and one canonical family from get_catalog(catalog='geometry'). family defaults to administrative; shape-backed families use direct bbox-to-exact-shape lookup without crosswalks. Single and bulk requests share this scoped contract. Current catalog: The same geography tools work worldwide across a cataloged baseline of 252 geographic entities, reaching up to Admin 2. Where additional country releases are available, the same calls automatically return deeper administrative tiers or maintained reference families.

Resolve WGS84 coordinates in exactly one selected scope and family. GLOBAL administrative finds Admin0; an ISO3 administrative scope finds its shallow country bank. MARINE requires one specific jurisdiction family (for example exclusive_economic_zone or high_seas), or water_body with water_kind=named or zone. The broad marine_jurisdiction category has no point route. No call crosses scopes or opens another family's bank. Discover families with get_catalog(catalog='geometry').
