Data Acquisition - Task Management: Upload your Data
1. Description
Data can be uploaded through the Data Acquisition module for each task.
2. Details
Step 1 - Click on the desired task or click on the three dots menu of the task and click on "Details".
Step 2 - This will open the "Details" view of the tasks. All information concerning the task is displayed in this view.
- On the left, there is the task progress status, and in the central section the task details (Properties, Location, Date,...)
- On the top of the central section, is the section for adding the field report and uploading the dataset.
- In the "DATASETS" section, mandatory datasets have an asterisk as a suffix.
3. Field report
The field report allows the pilot to add infield information related to the mission.
Step 1 - Click on the "ADD" button to fill in the field report.
The field report form is displayed.
Info
If some images are available on the task, then the date and time will be pre-filled from the last acquired image
Otherwise, a warning message will be displayed.
Note : it is still possible to set manually the date and time by unticking the checkbox if the field was automatically filled, of by setting them directly otherwise.
Step 2 - Add the following information :
- Date and time of the mission: mandatory for validating the field report
- Team and Pilot
- Weather Conditions
- Carrier and sensor
- Flight Parameters (Altitude, Flight Speed, Flight duration)
- Overlap
- Comment if need
- If the task is created from the Season Planner, the crop growth stage can also be indicated.
Important
Indicating the final date of the Data Acquisition mission is mandatory to complete the task in the Data Acquisition Module.
Step 3 - Click on "SUBMIT FIELD REPORT" to finish.
Step 4 - The button "ADD" should have changed to "VIEW OR EDIT", and the "complete" tag is also available.
4. Upload your visual data
Step 1 - Once the desired Task (task in "Scheduled" status) is selected, click on "UPLOAD DATA" to upload visual data from a mission.
Info
Click on "UPLOAD MORE DATA" for an upload in "Data captured" or "Data submitted" status.
Step 2 - The following window will be displayed and there are 3 different options to submit your data.
- (1) UPLOAD RAW IMAGES: upload raw images from data acquisition (for example drone images)
- (2) SEARCH ON ALTEIA: use images already stored in Alteia.
- (3) SUBMIT PROCESSED DATA: upload externally processed data (from an external software) or processed data stored in Alteia.
Warning
In the project details, the message "The project has been deleted" in place of the project name can have two meanings:
- The project has been deleted from the Data Studio module
- The user doesn't have sufficient rights to access this project
4.1 Upload raw images
4.1.1 Upload
Step 1 - Click on "UPLOAD RAW IMAGES" to select raw images from your computer or other sources.
Step 2 - Browse your computer to find the images you wish to upload.
Step 3 - Change the name of the survey if necessary.
Info
When creating a survey from a mission generated by the Season planner module, the proposed default survey name is “mission name - sensor type [SPL] [CT]”. When creating a survey from a task generated in the Data Acquisition module directly, the proposed default survey name is “mission name [CT]”.
Step 4 - Delete, add images, or add the metadata file if necessary.
4.1.2 Quality check
While uploading raw images, get access to quality checks. The list of criteria is available here: Data Acquisition - Raw Images Quality Check.
Quality check criteria can have 4 statuses:
- ✓ Valid: The criteria passes the quality check for this data set
- ⚠ Warning: There is a warning for the criteria for this data set
- ❌ Error: There is an important error in the criteria for this data set
- — Criteria not available for this data set.
4.1.3 Photogrammetry
Please have a look at the Photogrammetry recommendations.
Info
For multispectral data and if GCPs have been measured on the project, the upload has to be launched without photogrammetry ("ORDER PHOTOGRAMMETRY" button set to "off"), and the photogrammetry has to be launched in a separate step.
This is why the "ORDER PHOTOGRAMMETRY" button will be set to "off" for tasks with a sensor type "multispectral" and with the option "Use GCP" set to "true".
4.2 Search on Alteia
Step 1 - Click on "SEARCH ON ALTEIA" to use existing raw data saved in the platform.
Step 2 - Select a survey and click on "NEXT".
Step 3 - The quality check panel is displayed (see paragraph 4.1.2), click on "OK".
4.3 Submit processed data
- Select an existing survey or click on "+" to create a new one and click on "SAVE" to link data already processed with Aether or to upload other processed data.
- Upload the processed data or search the data within the survey (see the second red rectangle below).
Survey name
When creating a survey from a task generated in the Data Acquisition directly, the proposed default survey name is "mission name [CT]".
When creating a survey from a mission generated by the Season planner, the proposed default survey name is "mission name - sensor type [SPL] [CT]". And
Upload of Point Cloud file
When point cloud files are uploaded through Data Acquisition, it triggers its footprint calculation, which allows the point cloud coverage to be compared to the mission area.
5. View task coverage and metrics
For tasks with attached data sets, it is possible to view their footprint by clicking on "View Coverage".
If a mission area is associated with the task, then some metrics will also be provided (available for all datasets except raw images).
Task coverage and metrics with "linestring or multistring" mission areas:
Task coverage and metrics with "polygon" mission areas:
Description of the styles:
- The covered mission area is displayed in green
- The uncovered missing area is displayed in red
- The data set foot print is displayed in white.
Specificity for point cloud data sets
- Point cloud footprint is only available if the point cloud file was uploaded directly into the capture task.
- The CRS of the point cloud file must be defined during the upload step in order to visualize its footprint.
6. Results
- Once the data is uploaded (and completed if any) or once the data is linked to the Data Acquisition task, the tag "Available" is displayed next to the name of the input.
