New Project

Summary

The tool creates a new plot extraction project.

Parameters

Default location

• Output prefix: Prefix for output files (e.g., 2023_Field_1).

• Output path: Default location for output files.

List of data

• A list of all datasets (LAS or TIFF) to be used for plot extraction.

• The tool reads the header of each dataset and checks if the coordinate system is consistent.

Field boundary

• Base map: Dataset to be loaded as a base map for field boundary creation. For point cloud (LAS) data, the tool creates a digital surface model (DSM) with 10 cm resolution. For raster (TIFF) data, the tool resamples the data to 10 cm resolution (to avoid reading and displaying large image data).

• Extent (GeoJSON): Polygon that defines the area of interest. Users can load an existing field extent (created using a GIS tool) or create a new one. A sample extent file boundary.geojson is given below.

        }
    ]
}

Optional output geometry

• Centerlines: Outputs centerlines of the plant rows.

• Centroids: Outputs centroids of the segments.

Trial design information

• Field name: Name of the field.

• Unit: Unit used for segment length and width.

• Origin (magenta): Field trial origin. User can change the origin by double-clicking on a vertex in the graphic view.

• No. Ranges: Number of ranges in the trial.

• No. Rows: Number of rows in the trial.

• Segment Length: Nominal or estimated length of a segment. This parameter is used for calculating default detection parameters and creating as-designed plots.

• Segment Width: Nominal or estimated width of a segment. This parameter is used for calculating default detection parameters and creating as-designed plots.

• Segments Per Plot: Number of segments in a plot.

Example

Figure 1 illustrates a field planted in two row plots (the green rectangles represent plants). The parameters corresponding to such planting pattern are:

• No. ranges: 3

• No. rows: 6

• Segments per plot: 2
