Google’s map Data Request Sparks Debate in South Korea
SEOUL — A dispute over map data is brewing between the U.S.and South Korea, with Google’s long-standing request to export high-precision geographic data from the country facing continued resistance. The U.S. Trade Representative (USTR) has voiced concerns, highlighting South Korea as the only market maintaining restrictions on location-based data exports in its 2025 National Trade Estimate report (NTE), released late last month.
Google’s Persistent Pursuit
Google’s pursuit of access to detailed South Korean map data dates back to 2007, with subsequent requests in 2016 and most recently on February 18. The company seeks permission to transfer 1:5000 scale geographic data to overseas data centers. This level of detail, where 1cm on the map represents 50m in reality, allows for precise identification of locations, including alleyways.
Google argues that this high-precision data is crucial for fully implementing its Google Maps service.Currently,the service relies on a combination of aerial and satellite imagery,along with Points of Interest (POI) data and publicly available 1:25000 scale maps. Tho, Google contends this is insufficient for core functionalities like accurate navigation.
Economic Impact and Security Concerns
Google claims that South Korea, along with China and North Korea, are the only countries restricting such data exports. The company suggests that allowing full Google Maps functionality would boost tourism. A study by the Yonsei University East-West problem Research Institute supports this claim, predicting a potential increase in foreign tourists by 2027 if Google Maps were fully operational in South Korea.
The South Korean government has previously cited security concerns, particularly regarding sensitive sites like military installations. A past proposal involved Google establishing a data center within South Korea and blurring security-related locations on the map. Google rejected this proposal, arguing that no other country required local data storage. Though, as of 2024, Google operates 36 data centers globally, including facilities in Singapore, Taiwan, and Japan.
Domestic Competition and the Rise of Indoor Mapping
The potential entry of a fully functional Google Maps has sparked unease among South Korean map tech companies like Naver, Kakao, and T-Map Mobility. These companies have expressed concerns about Google’s adherence to domestic laws if granted access to high-precision geographic data.
Naver Map currently dominates the domestic digital map market, boasting over 26.5 million monthly active users (MAUs) in February, according to the Mobile Index. This surpasses the combined maus of T-map (14.35 million) and Kakao Map (10.56 million). Naver attributes its success to its “all-in-one platform,” integrating search, reservations, reviews, and comprehensive POI data.
T-map focuses on leveraging its navigation data, which generates approximately 6.7 billion data points annually, to create vertical business opportunities. The company provides real-time traffic information and APIs to various sectors, including logistics, delivery services, and government agencies. T-Map Mobility also supplies infotainment packages with navigation to over 18 automakers, including BMW and Mercedes-Benz. According to Park Seo-ha, vice president of T-Map Mobility, B2B transactions have driven significant growth, with a 23% year-over-year increase in customers and a 20% increase in API usage.
Kakao map prioritizes user experience within the KakaoTalk platform.Features like “talk Friends location Sharing” allow real-time location tracking within chat rooms. The company also offers “ultra-precision bus information” for local users. While these services are not directly profitable, Kakao Mobility, a subsidiary, generates revenue through its navigation-based taxi services, earning ₩212.6 billion last year from mobility platform fees alone.
Ecosystem Lock-in and API Strategies
The competition in the map tech sector is driven by the “ecosystem lock-in” effect. Naver aims to provide a comprehensive offline search experience through Naver Map, mirroring its online search dominance.
Maps offer opportunities to expand into various industries through apis.becoming a dominant API provider can generate substantial profits. Naver and Kakao offer APIs for many map-based services in South Korea. However, switching APIs can be challenging once a platform is established. One proptech company official noted the difficulty of migrating to another API after integrating a specific map API. Google’s 2018 decision to reduce free API provisions and increase costs for exceeding usage limits highlights the potential for leveraging API dominance.
Indoor Mapping as a New Frontier
With limited land area, South Korean map tech companies are exploring indoor mapping. This involves creating detailed maps of large and complex buildings like airports,shopping malls,and convention centers. In addition to providing indoor navigation, these maps can offer information about individual stores and facilities, expanding advertising opportunities through smart places (Naver) and location detail pages (Kakao). According to Lee Chang-min, Kakao Map Data Leader, indoor maps allow for swift updates, such as reflecting the presence of pop-up stores in department stores.
Customized Services and Local Expertise
Domestic companies plan to leverage their accumulated databases and local expertise to compete with Google’s potential expansion. Bang Kyung-hwa, a data leader at kakao, believes that global services will struggle to match the responsiveness of local apps in providing real-time information, such as tracking vaccine availability and mask supplies.
Google Maps in South Korea: A Data Dispute Explained
This article breaks down the ongoing debate surrounding Google’s request to export map data from South Korea. We’ll explore the core issues, the key players involved, and the potential impacts of this situation using a Q&A format.
What’s the Core Issue?
Q: What’s the main problem between Google and South Korea?
A: The primary issue is Google’s long-standing request to export high-precision geographic data from South Korea. The South Korean government has consistently resisted, creating a dispute, primarily centered on the export of map data.
Q: Why does Google want this data?
A: Google requires access to detailed map data, notably at a 1:5000 scale (where 1 cm on the map represents 50 meters in reality), to fully implement its Google Maps service in South Korea. This level of detail enables accurate navigation and is critical for core functionalities.
Q: What is the U.S. Trade Representative’s (USTR) stance on this?
A: The USTR has voiced concerns, highlighting South Korea as the only major market maintaining these restrictions in its 2025 National Trade Estimate report.
Why is South Korea Restricting Data Exports?
Q: What are the main reasons behind South Korea’s restrictions on map data exports?
A: The South Korean government primarily cites security concerns, particularly regarding sensitive sites like military installations.
Q: Has Google offered any solutions to address these security concerns?
A: Yes, a past proposal involved Google establishing a data center within South Korea and blurring sensitive locations on the map. However, google rejected this proposal.
