Creating a Task
- Open the cloud interface
- Press the Select Images and GCP button
WebODM Lightning can process any of the following:
- Color images (JPEG, TIFF), georeferenced or not.
- Multispectral and thermal images (TIFF).
- Video files (MP4, MOV, LRV, TS).
If you have a Ground Control Points file (
gcp_list.txt), select it along with the images.
WebODM Lightning provides various options (presets) designed for different scenes and use cases. You can further customize these presets by selecting the Edit button. For a comprehensive reference of all the task options that can be adjusted, refer to Task Options.
|Default||Generate a map and models at 2 cm / pixel max resolution|
|High Resolution||Generate a map and models at 1 cm / pixel max resolution|
|Fast Orthophoto||Generate a map, using fast-orthophoto|
|Field||Generate a map of a flat area that has been captured with nadir shots at a constant altitude. Very fast, but will not work for other scenes.|
|DSM+DTM||Same as |
|3D Model||Generate a more detailed 3D textured model compared to the default settings|
|Multispectral||Automatically perform radiometric calibration on multispectral images. This computes reflectance and temperature values in supported sensors.|
|Buildings||Attempts to improves the orthophoto quality in urban areas compared to the defaults.|
|Volume Analysis||Generates an elevation model at 1 cm / pixel max resolution, ideal for doing volume measurements.|
|Forest||Improves reconstrution settings for forest or high vegetation areas. Works for snow and sand also.|
The output resolution is limited by the ground sampling distance (GSD) of the images. For instance, if the images have a GSD of 5 cm / pixel, and you choose a resolution of 2 cm / pixel, the actual output resolution will be approximately 5 cm / pixel.
The choice to resize images depends on your goals:
|Yes (resize)||No (don't resize)|
|* Faster processing||* Slower processing|
|* Lower quality||* Highest quality|
|* Less disk space usage||* More disk space usage|
Review and Process
Once you're ready, press the Review button, double-check your choices and finally press Process. Processing can take a while. You will receive an e-mail notification when results are ready.
