The map is where you can view and explore the results of your processed videos alongside any other data available on the public map.
- Menu - Log in, view your Dashboard, and access resources.
- Living Map - Control how you view you map with Map Settings, Timeline, and Object Filters.
- Change Detection - See what changed by comparing a location at two different times.
- Overlays - Add and view custom overlays on your map.
- Tools - Perform in depth analysis of your map with a variety of tools.
- Search - Navigate the map by searching for a location.
With Object Filter, you can choose to display only certain types of objects in Point Cloud mode to help focus attention in your 3D map. By default, all objects are displayed. Object AI automatically detects and gives you the capability to grey out the following types of objects in your 3D map:
Object Filter integrates with other mapping tools including Change Detection, Color by object type, and Color by height above ground. If you use Object Filter with these other tools, you will only see changes, colors, and heights for the object types of you have selected.
Use the Map Button to open Map Settings.
- Default - A photorealistic rendering of your map.
- Point Cloud - Offers a more precise look at the raw 3D data and is excellent for more in-depth GIS analysis.
- Color - The default realistic rendering of your world.
- Infrared - Hivemapper is capable of generating 3D maps from Infrared video, which can reveal temperature-related information about a location. The global map does not automatically display maps made from Infrared videos.
- High - For maps that attain a high level of georegistration accuracy due to the presence of a lidar basemap. These maps segments are dark green on the Dashboard — the default map setting.
- Medium-Low - For maps that only attain a medium-low level of accuracy due to the lack of a lidar basemap for that location. These maps segments are green on the Dashboard.
- Terrain - Terrain data helps provide visual context. Hivemapper, by default, displays terrain data alongside your map to instantly identify if your map is in a valley, on a hillside, or near other geographical points of interest.
- Lidar - Whenever Hivemapper generates a map it automatically checks for, and imports, any existing lidar data from the mapped location. Lidar data can be viewed on the map to help provide a situational context and offer a snapshot of that location at the time of the lidar collection.
- Labels - Activate to display street names and other embedded tags.
Search videos from the map
Hivemapper lets you instantly access all videos that have recorded at that any given location by clicking that point on the map.
To access all videos that photographed a specific location:
- Click on any point on the map. Videos from that location will appear in playback windows on the right side of the screen
- A yellow dot will appear on the map and all videos. You can use this yellow dot to match the exact location on the map with frames in the video.
- Each video also has a playback bar at the bottom of the playback window. The sections of the video with your selected location will be in green.
- You can move the video playback window and access additional video playback controls, such as playback speed.
- Click on the 3D map again to unselect the location on the map and close the video search tool.
Change Detection allows you to compare two maps to highlight any physical volume that has been removed or added from the area of interest in your map.
To use Change Detection:
- Click the Change Detection button on the toolbar.
- Click on Filter to start Change Detection. By default, the map will show change detection between your map and the last lidar collection in the area. The map displays these changes in green.
- Use the slider to set the threshold of change (in meters) that you would like to detect and display. Choose a window on the right panel to detect changes between two different video collections. For video-to-video changes, red represents removed volume, and blue represents added volume.
- Hover your cursor over any location on the map to display the amount of change at that location.
- Click anywhere on your map to reveal the Before and After videos at a particular location. The map now displays a yellow dot on the location you clicked. Yellow dots also appear in the video players at the same place to help you match the positions. The playback bar on the video player also shows green segments for all times in the video that the location is available.
Hivemapper can also detect changes between a video and the lidar base map. Hivemapper will highlight in green any physical differences between the time lidar was collected and the time you collected your map. Click the lidar button to use video-to-lidar Change Detection.
