How do I process a dataset for weed detections?

Recall from Select Processing Type section above, that this mode should only be used for pre emergence fields, as all vegetation will be treated as weeds.

Navigation settings:

Sensor to airframe alignment, degrees

What is it?
These settings are intended for use with the SLANTRANGE 1p system which does not have inertial measurement. 2i, 2p, and 3p systems have inertial measurement and do not require offsets, however in rare cases of improper mounting and IMS interference, these settings allow some freedom to improve results.
When should I use it?
Unless you have already processed the dataset and used the Boresight alignment tool to find the proper offsets, leave these settings at 0 upon processing. Refer to the page Manually Adjust Boresight Alignment for instructions on how to apply these settings from within a Workspace.

Use compass data

What is it?
If your compass calibration, as performed with the 3p Toolbox app, is not up to date with your location and aircraft/mounting setup, or the compass data has significant interference in flight, changing this setting may improve map products.
When should I use it?
If you have turned on image footprints and see clear misalignment between flight legs, processing with Use compass data disabled may improve results.

Enhance geolocation

What is it?
This setting applies additional processing to the sensor's attitude metadata.
When should I use it?
We recommend always leaving this setting on for initial processing. If you enable Image footprintsand see rotational misalignment or image placement errors, processing with Enhance geolocationdisabled may improve results.

Altitude is constant

What is it?
This setting is for users mounting specialized SLANTRANGE systems to ground vehicles.
When should I use it?
(Do not mount your SLANTRANGE sensor to a ground vehicle unless it was specially manufactured for this use case.) Only enable this setting if your sensor is mounted to a ground vehicle. If this option is selected, you must manually enter the sensor's altitude above ground.

Sensor Calibration settings

Auto boresight alignment
What is it?
This setting applies flight-specific calibration to the alignment of each of the system's narrowband sensors.
When should I use it?
We recommend always leaving this setting enabled upon initial processing. If flying at very low altitude (approximately 15 meters or less), disabling this setting may improve results.

Auto flat field calibration

What is it?
This setting applies flight-specific calibration to vignetting correction processing.
When should I use it?
We recommend always leaving this setting enabled upon initial processing. If processing a very short flight, disabling this setting may improve results.

Map Generation settings

If a field boundary was previously saved for the dataset, selecting Trim to field boundary will automatically crop the dataset to that field boundary. To see if a field boundary exists for the data, open the Coverage map before processing.

Select an appropriate Map Resolution:

The map resolution can be set between 30cm and 10m depending on the size of the plants in the field and the size of the field. Typically, larger fields (80 acres or more) are Processed at 30cm or 50cm. Higher resolution maps require slower airspeeds, lower altitudes, and thus more images, resulting in larger Datasets and increased Processing time.

• In most cases, selecting a higher map resolution does not provide any additional information. SlantView does not "throw away" any data when resolutions lower than the highest (30 cm) are selected. The resolution defines the size of the Map Window's colormap "tiles", essentially defining the number of pixels in a high resolution image (seen in the Image Window) that are binned together to create an individual "pixel" of the colormaps seen in the Map Window.
• Select your map resolution based on the spacing of crops in the field. As a general rule, pick a resolution that is larger than the width of the empty space between plants. For example, if your crops are spaced 1 meter apart and 50cm resolution is selected, the colormaps shown in the Map Window may have "tiles" where no pixels of plant content exist, resulting in a map with blank areas between rows of crops. If your crop spacing is 30cm and 1m map resolution is selected, one "tile" of the Map Window can include content measured from several plants, and the color of that tile in the Stress Map will be a more accurate representation the sum of the plant stress in that 1x1m area.
• For vineyards, orchards, and other crops, that have a relatively large amount of bare soil between the individual plants even when mature, feel free to Recalculate maps with a few different map resolutions above and below the row spacing. Maps showing empty space between rows or individual plants may provide a more intuitive representation of crop health in the field.
• The Image Window displays the same high resolution images regardless of the selected map resolution.
