ZENRIN Maps API
Nov 5,2025

GISBox is a one-stop 3D GIS data editing, conversion and publishing platform that supports editing in multiple GIS formats such as OSGB/GEOTIFF/RVT, converting to 3DTiles/Terrain and publishing.

Introduction

ZENRIN Maps API is a geospatial service interface primarily used to provide map data, route planning, location search, and other functionality, similar to other mainstream map APIs (such as the Baidu Maps API or Azure Maps). It may support basic functionality such as 2D/3D map display, coordinate conversion, and real-time traffic information, but specific features should be referenced in the official documentation. Currently, search results do not directly mention a detailed description of the ZENRIN Maps API. It is recommended to consult its official website or developer platform for more accurate technical documentation.

File Structure

The ZENRIN Maps API file structure primarily consists of the following core components:

Map Container: This is the DOM object that holds all layers, markers, and controls. An ID must be pre-assigned to initialize a map instance.
Layers: This supports a variety of layer types, including standard vector layers, satellite layers, and real-time traffic layers. It also allows loading third-party map services or custom image/video layers.
Vector Overlays: These overlays are geometric paths (such as polylines and polygons) that are applied to the basemap, maintaining their actual geographic extent as the map zooms.
Markers: This provides a variety of marker types (such as custom icon markers, dot markers, and text markers) and a massive point aggregation function for identifying geographic locations.
Map Controls: These are interactive components that float on top of layers, such as zoom controls and scale bars, to enhance the user experience.
Map Files: These define map parameters using JSON or similar structures, including structured data such as projection settings, layer properties, and symbology configuration. API key and authentication file: A separate configuration file is used to store the developer key and must be loaded in advance during initialization to ensure service access permissions.

Pros

Stability and Professionalism: Maintained by a professional team, it offers standardized interfaces and documentation, stable feature iterations, and is suitable for enterprise-level applications.
Data Integrity: Built-in high-precision map data (such as roads and points of interest), supporting advanced features like real-time traffic and 3D maps, reducing the cost of building your own data.
Technical Support: Official technical support and guaranteed updates are provided to reduce development risks.

Cons

High Cost: Commercial licensing fees are high, which may not be suitable for startups or projects with limited budgets.
Functional Dependence on Vendors: New features must be updated by the vendor, and the underlying code cannot be modified independently.
Potential Limitations: There is a risk of development interruption due to changes in terms of service (such as mandatory watermarking or interface adjustments).

Application Scenario

The ZENRIN Maps API is suitable for enterprise applications requiring high-precision geographic data, such as real-time route optimization and vehicle tracking in logistics and delivery, as well as store location analysis and business district heatmap generation in the retail industry. It supports indoor navigation and geofencing, enabling integration into shopping mall guides or campus management systems, while also providing data visualization tools for urban planning. Furthermore, the API's multi-platform compatibility (web/mobile) makes it an ideal solution for developing cross-device location-based services.
