Apart from that, creating or obtaining data that can represent geographic
functionality, attributes, and geometric data for a full range of structures, such as data
types, coordinates of objects, and properties. This data is crucial for the accurate and
effective display of the map.
Next, it is important to decide on the type of TileMap to use. There are two types
of TileMap, which are raster and vector tile, and both play different roles. The
TileMap is a grid used to create a complete map of itself consisting of tilesets, which
are small pieces that make up a large TileMap. This step is important to ensure that
the map is created efficiently and accurately.
Ultimately, the map is displayed using the pre-selected programming language and
framework to add features like markers, pop-ups, and overlays. This step is crucial for
making the map interactive and engaging for users. Overall, the implementation of a
2D map requires careful planning and attention to detail to create a map that is accu-
rate, efficient, and visually appealing.
Furthermore, implementing a 3D map is quite similar to 2D map in the first few
steps but in addition it needs more completion because of its complexity in 3D space
displayed on the map. Initially, selecting a suitable rendering engine that can
effectively render 3D rendering data on the map. This choice can greatly impact the
performance and quality of the map.
Next step is adding textures to 3D models that can make them more visually
appealing and help users better understand the information and characteristics
represented in the map. Textures can be applied to various features in the map such as
buildings, roads, and natural landscapes.
To make the map more interactive, it is important to implement features that allow
users to explore the map in more detail. This can include interactive elements such as
zooming into 3D models to render an indoor map model, providing the user with a
more detailed view of the space. These interactive features can make the map more
engaging and useful for users.
Overall, implementing a 3D map requires careful attention to detail to ensure that
the map is not only visually appealing but also interactive and informative. By
selecting a suitable rendering engine, adding textures, and implementing interactive
features, a 3D map can be created that effectively communicates spatial information
to users.
