For example, self-driving cars require information such as lane and signal information as well as the height of roads and facilities for safe operation. In response to these demands, the Ministry of Land, Transport and Maritime Affairs is implementing cyber national territory (3D map data) similar to the real world by adding height and image information to existing 2D map data.

However, it is not limited to this. For convenience of explanation, this document takes the case where the first resolution is SD as an example.

According to one embodiment, the user device 110 may search a route based on first map data in response to a user's route search request. The user device 110 may check route information for the search route and generate (or determine) route information based on the first map data.

The route information may include the vehicle's current location information (e.g., geographic location coordinates, driving direction, driving lane (e.g., three-lane road)) and lane change information, or may be related to the current location information and lane change information. For convenience of explanation, this document takes the case where route information includes current location information and lane change information as an example.

According to one embodiment, the user device 110 may check request item information corresponding to preset processing performance. The request item information may be set by the user, or may be set automatically according to the processor specifications of the user device 110. For example, the request item information may include at least one of requested object type information, request lane number information (hereinafter, corresponding to 'specified number'), request resolution information, and 3D shape image use/non-use information. there is.

For example, the user device 110 may receive a portion of the second map data all at once and output an area corresponding to the current location in the portion of the received second map data while updating it according to changes in the current location. A portion of the second map data is prepared at a second resolution and may include lanes, lanes, road facilities, surrounding facilities, and variable objects as three-dimensional shape images.

For example, the server device 120 may generate part of the second map data by converting at least one object according to the request item information received from the user device 110 into a two-dimensional shape. For example, if the request item information includes an unused request for three-dimensional shapes for at least some of the object types, the server device 120 replaces some objects with two-dimensional shape images instead of the default three-dimensional shape images. Part of the second map data may be generated. In this process, the server device 120 may convert part of the second map data to a resolution lower than the second resolution (eg, may be the same as the first resolution).
