Places - GERS Property ID & Location Intelligence

GERS is the Global Entity Reference System: an open, universal system of persistent identifiers for geospatial entities (places, buildings, roads, addresses) published by the Overture Maps Foundation. It is explicitly designed to be an open registry that makes joining datasets and onboarding data much simpler.

No. GERS covers all geospatial entities across industries - everything from buildings and roads to places used by automotive, logistics, urban planning, local search, and more. That broad scope is exactly what allows hotels, restaurants, golf courses and wellness centers to interoperate with car rental systems, mapping platforms, public administration datasets and many others.

Yes. Overture published GERS with documentation, tooling and bridge files that let organizations join their existing records to GERS IDs via a single-column join, which is exactly the practical onboarding pattern hotels and vendors need. That means hotel tech stacks can begin mapping to GERS immediately.

Yes. You can maintain an authoritative hotel registry or internal record and publish pointers that map that record to the GERS ID for the physical place. That keeps your control of the authoritative data while gaining universal joinability with all other datasets that use GERS. Overture explicitly supports bridge files and linking patterns for this purpose.

Yes. GERS is part of Overture’s open map data initiative and is released as open data with published documentation and datasets. That openness eliminates licensing friction and vendor lock-in that can arise from closed or paid registries.

Permissioning and privacy controls are orthogonal to the existence of a global ID. The right pattern is to use GERS as the neutral identifier while implementing access control, privacy-preserving pointers, authentication and consent at the layer that holds the sensitive data. That model avoids duplicating identifiers while keeping private data protected under your governance.

AI systems need deterministic identifiers to ground facts to the right real-world assets. GERS supplies persistent IDs and changelogs, making it easier to trace, audit and bind data to a place. That improves data retrieval accuracy, auditability and reduces the risk of AI making inconsistent or fraudulent inferences about properties.

Hospitality companies should map their internal property records to GERS IDs using Overture’s bridge files. For hospitality-specific needs, build a metadata layer that references GERS IDs rather than issuing an alternative global identifier. That gives immediate interoperability and keeps future integration costs low.

Use a GERS ID from Overture Maps' Global Entity Reference System, an open worldwide registry of persistent place identifiers that works across mapping, distribution, payments, public datasets and AI pipelines; GERS IDs have already been assigned to a vast number of places, so in many cases your property already has one and you only need to look it up in the GERS dataset. You can self-serve with Overture’s datasets and documentation, have a developer join your records using GERS bridge files, or if you are an inHotel customer, inHotel will map and verify your property's existing GERS ID at no charge.

Yes. Most hotels already have one or more globally unique identifiers: GERS has preassigned IDs for a vast number of places, including bed and breakfasts, hotels, hostels, lodges, golf courses, guesthouses, motels, resorts, serviced apartments and many vacation rentals. Other global systems that likely include IDs for your property are Google Maps (Place IDs) and OpenStreetMap (OSM) IDs. GERS aggregates place data from multiple sources and is purpose-built as a free, open, universal place identifier that supports interoperability both inside and outside hospitality. You can discover your GERS ID in the Overture Maps Explorer (https://explore.overturemaps.org) or by using inHotel’s GERS discovery and management tools.

The practical path is to adopt GERS IDs as the canonical identifier for each property or point of interest, then use an API that exposes those IDs for lookup, search and synchronization. GERS gives you stable, open IDs for places across releases so you can join your own data and partner feeds reliably. inHotel’s GERS API lets you query places by ID, location area, category or brand, then store that GERS ID as the shared key in your system. That way, every integration points to the same place, rather than juggling dozens of partner specific codes.

If every hotel, restaurant, airport, tour operator or car rental in a destination is associated with a GERS ID, their AI agents can use those IDs as a shared reference for "this exact place." inHotel’s location intelligence service lets each supplier register agents against the GERS place record and then use an API to query other agents around that location by role, such as Reservations, Concierge, or Rental Sales Agent. This allows an AI concierge for a hotel to discover and collaborate with nearby suppliers' agents, coordinate recommendations or bookings, and still keep each company’s logic and policies separate, all anchored on a common, open place ID.

Grounding an AI agent means tying its knowledge and actions to concrete entities like your hotel, outlets and nearby POIs. With GERS, each of these entities has a stable ID that persists across data releases and partners. Using inHotel’s GERS API, you can fetch the canonical place record for your property, enrich it with your own metadata, and expose that to your AI assistants as the single source of truth. The same API can then be used to search nearby places for recommendations, resolve partner codes, and attach agent profiles, so your AI behaves consistently and context aware across channels.

Yes. You can expose an AI assistant for your restaurant or hotel on the map so people can ask common questions. Using GERS-backed place records makes the agent discoverable across platforms while keeping the source of truth with you: you decide what the assistant can answer and whether it can perform transactions such as bookings. inHotel can help map your place to a GERS ID, register an agent endpoint and connect it to your systems for authoritative data. If you want help getting started, we can set up a basic FAQ assistant for free or scale it into a fully featured concierge that integrates with your booking and other systems.
