Who can use this feature
Owners of an Essentials, Professional, or Pro + workspace, as well as Editors in Professional and Pro + workspaces.
Sometimes the drones we use will conveniently create a new folder for each individual flight, separating our drone mapping data into folders on the SD card. So even if you just swap out a battery before sending the drone to return to where it left off, a single mapping mission can contain data in multiple folders.
When uploading and processing these data, it's important to remember:
A drone mapping dataset only contains images that are adjacent over space and time.
In the examples below, (1) is the only option that consists of a single dataset. All others represent multiple datasets.
Consecutive flights in adjoining locations (no gaps spatially or temporally);
Non-consecutive flights in adjoining locations (no gaps spatially, but data from different dates or times of the day);
Consecutive flights that are not directly adjacent (gaps spatially);
Non-consecutive flights that are not directly adjacent locations (gaps spatially, and data from different dates or times of the day).
To achieve the best results in processing your data, if you captured your data as per scenario 1 (no spatial or temporal gaps) follow this process:
Upload the parent folder containing all sub-folders, or simple drag and drop all the folders into GeoNadir at once
Opt to merge into a single dataset
This will return a single orthomosaic / DSM / DTM combo.
If you have multiple folders of data captured under any other scenario, please instead choose to keep as separate datasets.
You will then receive an orthomosaic / DSM / DTM per folder uploaded.
If you upload the folders separately when they actually belong as a single dataset, they cannot be merged and re-processed later. You will need to re-upload the entire dataset again.
Electing to merge data that are not adjacent over space and time can cause errors in reconstruction; processing may fail entirely; the final product may be suboptimal; and file sizes will be significantly larger.
