Video Map is a new form of map expression, which is based on video spatialization, integrates virtual and reality through computer vision technology, and carries out real-time geographic information visualization and intelligent geographic analysis. After the mapping relationship is established between the video and the geospatial coordinates through registration, GIS vectors such as points, lines, surfaces, texts, pipelines, terrains, images, aerial landmarks and Raster Data can be superimposed to enhance the Display Effects of the video and enrich the Map Information.
Video and GIS data are combined to make maps, through the authenticity, timeliness, information richness and content diversity of Video Enhancement GIS, and GIS also enhances the spatiality and information richness of video data, so that users can get more information while watching maps.
New/Open VideoMap
There are two ways to Create Video Map Window:
- Click Home tab-> Browse-> Video Map.
- Workspace Manager-> Video Map node Context Menu-> Create Video Map Window.
Open VideoMap has the following two methods:
- At the Workspace Manager-> Video Map node, double-click the saved Video Map to open it.
- Double-click the Video Dataset in Workspace Manager to open it to the Video Map window.
Add Video and GIS Data
In the Video Map window, you can Add Video Data set, 2D/3D point/line/regionDataset, Text Dataset, etc. Video data can be superimposed and displayed with geographic data after registration. You can drag a Dataset directly to the opened Video Map window or add it through Add to New Video Map or Add to Current Video Map in the DatasetContext Menu. It also supports operations such as setting Layer Style, Create Thematic Map, adjusting Layer Display Order, and removing layers.
Note: Add to Video Map of Geographic Coordinate System data to the window is not supported.
Set Layer Style
Video Map支持设置点、线、面、Text的Layer Style，在Layer Manager中选中待设置风格的图层，选择Context Menu中的Layer Style，在弹出的Select器对话框中，设置对象符号和风格，详细说面请参见Symbol Style Settings章节。
Video Map Properties
Click the right mouse button in the Video Map window and select the attribute option to set the following parameters:
- Display Time: Select the Display Time check box to display the time in the upper right corner of the Video Map window. As the video plays, the time displayed is the start time + Play Video time.
- Start Time: set the Display Time for the initial video playback.
- Time format: two time display formats are provided: yyyy-MM-dd HH: mm: SS displays year, day, hour, minute and second; HH: mm: SS displays hour, minute and second.
- Show Video Parameter: Select the Video Map-> Video Parameter Information-> Show Video Parameter check box. The Camera Intrinsic Parameters and Extrinsic Parameters are displayed in the Video MapUppe-left corner of the window. Including horizontal view, vertical view, pitch angle, yaw angle, camera coordinates and other information.
Video Layer Properties
- Video Valid Bounds: Support setting of effective Visible Bounds of video: to improve the accuracy of Video Registration.
