MapFan DB Display Map Database

Landmark icons, 3D landmark objects

Data visually representing famous buildings throughout Japan.
"3D icon data" are full-color BMP format icons that depict buildings in three dimensions. By overlaying them on a map, they achieve high visibility, enabling intuitive navigation and guidance.
"3D Landmark Objects" are data that represents famous buildings as three-dimensional models, allowing for the display of realistic 3D visuals on maps.

Data Details

Landmark icons and 3D objects that enhance visibility and create a sense of depth.

    • Landmark icons:
      These are full-color bitmap icon data featuring uniquely visualized images of famous buildings.
      It is provided as a set with configuration files for displaying on maps, and by creating a sense of three-dimensionality in buildings even on flat maps, it enables easy recognition and clear guidance.
      It can be used as a visual accent suitable for navigation maps, tourist information maps, and more.
    • 3D landmark objects:
      This is an OBJ format model data that displays well-known landmarks in 3D on buildings (building footprint polygons) on a detailed map.
      Text data recording the model's reference coordinates and the latitude and longitude information of each vertex is also provided, enabling accurate placement in GIS and 3D map applications. *OBJ data consists of three types: [object files], [material files], and [texture files], which are combined to achieve 3D representation.

Expected usage

  • By displaying this data on car navigation maps, landmark buildings can be visually identified and used as markers during navigation. This enables more intuitive and less confusing route guidance.

  • By displaying icons of famous buildings on maps in tourist guide apps and other similar applications, tourists can be provided with visual landmark information, thereby improving the quality of their travel experience.

  • By utilizing 3D landmark objects in AR (augmented reality) navigation, virtual structures are overlaid onto real-world scenery, supporting the user's sense of direction and location.

  • By combining building height data with 3D landmarks, a realistic urban landscape model can be constructed. This can be used for various simulation and analysis tasks, such as urban planning, landscape evaluation, and disaster prevention design.

FAQ

What cities and tourist destinations does this landmark dataset cover?

This database covers famous and prominent buildings throughout Japan. It primarily includes structures with distinctive shapes, such as skyscrapers, historical buildings, and towers, focusing on landmarks that offer high visibility and effective guidance.

What format is OBJ data in?

The OBJ format is a lightweight text-based format that describes the shape (vertices, faces, normals, etc.) of 3D objects. It offers high compatibility with many 3D software and development environments.

How can the reference coordinates included in 3D landmark objects be utilized?

This is used to place 3D objects in the correct location on a 2D map. This allows for precise display on the map.
