Video maps represent a novel cartographic expression form that integrates virtual and real elements through computer vision technology. Based on spatialized video, they enable real-time geographic information visualization and intelligent geospatial analysis. Registered videos can overlay GIS vector and raster data such as points, lines, regions, text, pipelines, terrain, imagery, and aerial landmarks, enhancing video display effects and enriching map information to achieve mutual reinforcement between video and GIS data visualization.

Registered videos can be added to maps for integrated cartography with GIS data. By overlaying data like points, lines, regions, terrain, and imagery with video, it enhances the authenticity, temporality, informational richness, and content diversity of GIS, allowing users to obtain more information while viewing maps.

Similarly, after spatial registration establishes mapping relationships with geospatial coordinates, video maps can directly overlay 2D/3D vector data like points, lines, and regions. They also support style configuration for vector datasets and thematic map creation, thereby enhancing the spatial characteristics, informational richness, and display effects of video data.
