A Digital Territorial Dispute Lasting 18 Years: At its Core Lies the ‘High-Precision Map Data’, Referred to as the Oil of Future Industries.

  • Understand why global big tech companies are obsessed with South Korea’s map data.
  • Grasp the government’s security, legal, and industrial logic surrounding the export of map data.
  • Forecast the impact of this dispute on our future technologies (autonomous driving, AR).

Prologue: Seoul, Lost Giants

It is no longer unusual to see foreign tourists in the heart of Myeongdong, Seoul, looking confused while using Google Maps. Behind this minor inconvenience lies a massive war over ‘map data’ that has lasted for 18 years. On one side are Google and Apple, and on the other is the South Korean government, which emphasizes ‘security’ and ‘sovereignty’.

This is not just an issue of navigation apps. It is a story about the 21st-century digital territorial war, or ‘map war’, over the astronomical value of ‘high-precision map data’ that will determine the direction of future industries such as autonomous driving and augmented reality (AR).

The New Oil: Map Data for Machines’ Eyes

The digital maps we commonly use are designed for people. However, the ‘1:5000 scale high-precision map (HD Map)’ that Google and Apple desire is a completely different dimension of data created for the ’eyes’ of machines.

Beyond Navigation: The Blueprint for Digital Twins

Currently, the Google Maps used in South Korea is at a 1:25,000 scale, where cars are just tiny dots. However, the 1:5000 scale map can capture 50 meters in 1 cm, allowing it to identify even narrow alleyways.

The real value lies in the information contained within. HD Maps are akin to ‘Digital Twins’, replicating the real world down to the centimeter. Information that machines can read is layered, including lane types and widths, road inclines, the three-dimensional positions of traffic lights, and curb heights.

This data can only be obtained by special vehicles equipped with LiDAR sensors that traverse the country, and the government has invested over 1 trillion won in taxes for decades. This is why it is not just simple information but a valuable ’national asset’.

Spatial computing devices like Apple Vision Pro use high-precision maps as a canvas to merge reality and the virtual world.

The Core Foundation of Future Technologies

  • Lifeline for Autonomous Vehicles: HD Maps are essential for fully autonomous vehicles. They allow for location detection within a 10 cm margin of error, even in heavy rain, fog, or tunnels where GPS signals are lost. Waymo, a subsidiary of Google, can only operate its autonomous taxis on HD Maps. The absence of HD Maps in Korea means that Waymo’s dream cannot even begin in Korea.
  • Merging Reality and the Virtual: AR devices like Apple’s Vision Pro use HD Maps as a canvas to perfectly understand the three-dimensional structure of physical spaces and overlay virtual information on top.

In this way, high-precision map data serves as the ‘operating system (OS)’ for a future innovation industry projected to be worth approximately 796 trillion won.

The Courtship of Giants: Google and Apple’s Different Agendas

Why are Google and Apple so obsessed with South Korea’s map data? One side dreams of ‘completing a global empire’, while the other aims to ‘seize the future ecosystem’.

Google’s Hardline Approach: “All Roads Lead to Google Servers”

For Google, South Korea is the only gap in its global map service portfolio. Google has maintained that it must bring data to its global integrated servers to ensure data quality. During negotiations in 2016, when the South Korean government requested that security facilities be blurred, Google retorted, “Then please provide the coordinates of all security facilities.” This was essentially a demand to hand over a complete list of national secrets, and the negotiations broke down.

Apple’s Soft Approach: “We Will Follow Korean Laws in Korea?”

In contrast, Apple presented a much more conciliatory card by utilizing data from domestic operator SK T Map Mobility and accepting government security requirements. Crucially, Apple operates a data center in Korea, allowing it to process data without exporting it abroad. This could be the key to fundamentally resolving the government’s greatest concern: the issue of ‘data export’.

Digital Fortress: South Korea’s Triple Defense

The reason the government has steadfastly resisted for the past 18 years is due to three solid pillars: law, security, and industry.

  1. First Defense: Law - The Spatial Information Management Act
    This law fundamentally prohibits the export of precise map data, such as 1:5000 scale maps, without the permission of the Minister of Land, Infrastructure and Transport.
  2. Second Defense: Security - An Ongoing War
    In the reality of being the world’s only divided nation, the combination of high-precision map data and satellite images could expose the coordinates of national infrastructure such as military bases. This is akin to handing over precise strike coordinates to the enemy.
  3. Third Defense: Industry - Protecting Local Champions
    There is a sense of ‘data sovereignty’ that we cannot hand over national assets created with massive taxes to foreign companies for free, and there is a fear that domestic companies like Naver and Kakao could perish if Google enters. Naver and Kakao have built empires in commerce and mobility centered around maps, so exporting map data could shake the foundation of their business models.

Timeline of the South Korean Map Data Dispute (2007-Present)

Date Major Event Key Details and Background
2007 Google requests first export of map data Request for 1:5000 scale map data ahead of Google Maps’ South Korea service (2008).
2008-2010 Government denies Google’s request Decision based on national security reasons and current law (Survey Act) prohibiting export.
2014 Establishment of ‘Map Export Consultation Body’ Changed from a single review by the Ministry of Land to a joint review by relevant ministries through legislative amendment.
June 2016 Google requests second export of map data Officially re-requested after the first request was denied for 8 years.
November 2016 Government denies second request Announced that it could exacerbate security threats in the context of inter-Korean tensions.
2023 Apple requests first export of map data Government denies request citing national security.
February 2025 Google requests third export of map data Reapplication for 1:5000 scale map data after 9 years.
June 2025 Apple requests second export of map data Proposes more conciliatory conditions, such as using SK T Map data and accepting government security requirements.

Comparison/Alternatives

Comparison of Map Data Policies Worldwide

The map war in South Korea is not an isolated battle. It is part of a massive chessboard where the world is contemplating how to draw digital borders.

Country Core Principles Rules for Foreign Companies
South Korea National security and protection of domestic industry Principle of prohibiting the export of high-precision data above 1:5000 scale. Proposal for mandatory installation of domestic data centers.
China Absolute state control and data sovereignty Must establish joint ventures (JV) with Chinese companies. All servers and data must be located within China. Mandatory use of a state-designated distorted coordinate system (GCJ-02).
India Selective opening for domestic industry development Direct collection of high-precision data and ground measurements prohibited. Data licensing only possible through APIs from Indian companies.
European Union (EU) Collective data sovereignty Prevents data monopolies by specific companies and promotes data sharing through interoperable collective data spaces (Data Spaces).

In this flow, the United States has defined South Korea’s regulations as a ‘digital trade barrier’ and is applying trade pressure, making this issue transcend technology to become a diplomatic and geopolitical matter.

Three Doors to the Future

After 18 years of confrontation, we now stand at a crossroads of choice. Before us are three doors. Which door would you choose?

  1. The First Door, ‘Status Quo’: Safe in the short term, but a path of ‘digital isolation’ that risks being cut off from global technological flows in the long term.
  2. The Second Door, ‘Conditional Opening’: A ‘sandbox’ model that opens data only for specific areas or purposes. Security risks are reduced, but it is likely to remain a stopgap measure.
  3. The Third Door, ‘Mandatory Domestic Data Centers’: Currently the most realistic compromise. It binds data within Korean territory to alleviate security concerns while leveraging the technology and capital of global companies.

Conclusion

The 18-year-long map data war is a symbolic event redefining sovereignty in the digital age.

  • Key Summary:
    1. High-precision map data is a core infrastructure for future industries such as autonomous driving and AR.
    2. The government prohibits the export of data citing security, legal, and domestic industry protection.
    3. ‘Mandatory domestic data centers’ are emerging as a realistic alternative to balance security and innovation.

Depending on which door we choose, the map of South Korea’s digital economy and future industries will be completely redrawn. This is why we must pay attention to the end of this invisible war.
