From your Dashboard, you can upload new videos, as well as view, manage, and export your existing videos.
First, make sure you are uploading from a location with a stable internet connection since the videos from your drones will often be several gigabytes in size.
Then, from your Dashboard click Upload, which opens the Upload Window.
- Enter an Upload Name.
Adding an upload name can help organize your videos in the Dashboard. Later, you can also search for your videos by the Upload Name.
- Select a Map Resolution.
Map resolution can be adjusted based on your processing time and quality needs.
- High quality - Slightly greater detail but will take longer to process.
- Normal quality - Recommended for most mapping projects.
- Low quality - Slightly lower detail but faster to process.
Processing time will significantly vary based on your video length, resolution, and complexity of the location being mapped.
- Select your files.
Drag your video files and any corresponding metadata files into the uploader. The file names for the metadata should be identical to the corresponding video file names with the difference of having a *.srt or *.csv extension instead. For videos without metadata, you will be prompted to add a location estimate after the video has been uploaded.
- Click Upload.
Your files will begin to upload. Leave the browser window open until the process is complete. Your videos will then appear in the Dashboard.
If you accidentally close the browser or lose internet connectivity, inspect your Dashboard to see which file was the last to sucessfully upload. Then repeat Steps 1-4 for the remaining data.
Once your videos have been uploaded, Hivemapper begins transforming your video to a 3D map. From this point onwards the process is entirely automated. To produce the map Hivemapper will work these videos through the following stages:
|Video Transcoding||Converts video into a web friendly format for online viewing.|
|Frame Selection||Intelligently extracts frames from your video.|
|Clustering||Groups extracted frames together based on similarity.|
|Structure From Motion (SFM)||Finds the location of all the frames relative to each other in 3D space and generates a sparse point cloud.|
|Dense Reconstruction (MVS)||Adds additional points to create a more dense point cloud.|
|Mesh Creation||Generates a textured map from point cloud data|
|Imagery||Registers map to satellite imagery when no GPS metadata is available for your video.|
|Georegistration||Registers map to the global map|
|Video Mapping||Links video frames to the 3D map.|
|Merger||Integrates the new map into the global map.|
|Change Detection||Generates Change Detection data against overlapping maps.|
A video will appear in the Video List once it starts uploading. Clicking on any video on the left side of the screen will highlight the row in grey and open additional details on the right.
- Video and coverage area.
At the top, you can play your video and review the areas where your video has generated a 3D map.
- View 3D map for this video.
Videos that have finished processing and have successfully generated any 3D map will have the View 3D map for this video button enabled. Clicking the button will open a new tab in your browser to view and explore the resulting map.
Add Notes to your video that are searchable in the video list. These Notes are also accessible when viewing the video on the 3D map.
- Additional video information.
Below the Notes are more information about your uploaded video including:
- Video ID - Hivemapper's internal label used to reference your video
- Video recorded date - extracted from the metadata
- Video uploaded date
- Owner - your user name
- Video dimensions - the pixel width and height
- Map resolution chosen at upload - High, Medium, or Low
Hivemapper is continuously improving the ability to turn your video into a 3D map with every release. Use the Reprocess button to generate a 3D map from your video using the latest version of Hivemapper.
- More information.
Click See details to open the Processing details information.
- Processing priority.
You may want a particular video from your batch to finish processing first. If so, set the Processing priority to High for the video you need first and use Low priority for other videos that can wait. The default Processing priority setting is Medium.
- Segment statuses
The Segment statuses bar shows how Hivemapper has deconstructed a video file into smaller segments. The colored bar represents a timeline of your video that shows how different sections contribute to the 3D map.
Generating 3D maps from videos is a resource-intensive process. Longer videos - and even shorter videos covering a more substantial area - may be parsed into multiple segments. Hivemapper intelligently selects and groups frames to deconstruct a larger area of video into smaller pieces, which are later combined. Some sections of video may be unsuitable for generating a 3D map (e.g., shots of the horizon), which Hivemapper automatically disregards.
Segments are in one of seven categories. Segments that are processing or produced no map are either:
Blue - the segment is currently processing or is pending the start of processing.
Red - the segment was processed but produced no map.
Map segments that successfully generate a 3D map are separated into there categories based on how accurately they georegistered:
Light green - the segment was mapped but couldn't be georegistered into any layer of the global 3D map. Do not rely on measurements or coordinates taken from this map.
Green - the segment was mapped and georegistered into the Medium-Low accuracy layer of the global 3D map.
Dark green - the segment was mapped and georegistered into the High accuracy layer of the global 3D map.
Additionally, segments may be:
Black - the segment was mapped and added to the global 3D map but was subsequently explicitly removed (blacklisted).
Grey - an unusable section of the video. It's not considered a segment, but it's shown in the status bar because it has a duration.
- Segments list.
To view individual segment maps, select any Finished segment in the Segments list and click on the image below Preview of this segment to open a new tab with the 3D map.
Add location estimate
For videos that do not contain any flightpath metadata, you will see an Action Required alert in the video list. In the video detail panel, you will find a Set Location Estimate button. This button will allow you to set a location for Hivemapper to georegister your map manually.
Navigate the 2D map to the approximate capture location of your video. Hivemapper will search a 1.5-mile radius around your specified location, so absolute accuracy is not required. Click the Set Location Estimate button to attempt to georegister the video.
If you don’t provide a location estimate, your video will still generate a 3D model. However, Hivemapper cannot add your map to the global merged map without completing this step. After making a selection, a Change Location Estimate button will now appear in the Dashboard. This button allows you to relocate your map if your previous location estimate is inaccurate.
If your video completes processing before you can set the location, all resulting maps will appear as Failed to register against satellite imagery. Once you set a location, these segments will automatically restart processing.
Remove map segments
You may want to remove a successfully georegistered map from the global map when:
- a map is flawed.
- a map contains sensitive video content.
To remove your video segment from the combined map, select the segment on the Segment list on the Processing details panel. Under the preview image, click Remove this segment from the global 3D map.
It may take some time for the segment to be removed from the global map. Additionally, the segment will still be available for viewing in the Segment list. Once the process is complete, a new option to Return this segment to the global 3D map will appear.
This process only removes one segment made from your video. If your video file produced other successfully processed segments, they would still remain in the global map. To remove all parts of your video from the map, be sure to remove all successfully generated segments.
Export maps from dashboard
Hivemapper can export your maps in a .las format for viewing in 3rd party applications. To export your maps from the Dashboard:
- In the video list check all the boxes for videos that have maps you want to export.
- Click the Export button.
- Go to the Export Manager.
- Select the export that you want to download and cofirm that the export is complete.
- Click the Download Export button.
