8/9. Analysis & Report

Overview​

The Analysis and Reports modules in TytonAI enable users to apply post-classification analytics to a defined study area. Core features include vegetation cover analysis, plant health scoring, individual plant segmentation, bare area detection, and erosion risk assessment. Results can be exported in both graphical and tabular formats.

Key Tools and Functions​

ToolDescription
Flora / Vegetation CoverCalculates percentage cover for each vegetation class based on classification results.
Plant HealthAssesses vegetation health using selected vegetation classes and spectral indices.
Individual Plant SegmentationSegments vegetation at the individual plant level using DSM and classification input.
Bare AreasIdentifies areas with minimal or no vegetation based on proximity thresholds.
ErosionHighlights erosion-prone zones. Requires DSM input before metrics can be calculated.
Report GeneratorCompiles analysis into downloadable report formats.

Workflow Steps​

1. Select Classification & Study Area​

  • Navigate to the Analysis panel.
  • Choose a classification and the Study Area boundary for the analysis.

2. Enable and Configure Metrics​

a. Flora / Vegetation Cover​

  • Toggle ON to run vegetation coverage calculations.
  • Automatically uses the active classification to compute the % cover of each vegetation class.

b. Plant Health​

  • Toggle ON to begin health analysis.
  • Inputs:
    • Health Band: Select the metric used to assess plant health (e.g., NDVI, MSAVI).
    • Health Min/Max: Optional thresholds for bounding the health values.
    • Health Offset Value: Adjusts the base health score by a fixed value.
    • Non-Vegetation Class List: Add classes (e.g., Track, Rock, Debris) to exclude from health calculations.

c. Individual Plant Segmentation​

  • Toggle ON to detect and segment individual plants from classification data.
  • Inputs:
    • DEM Band: Select DSM (Digital Surface Model) as the elevation input.
    • Segment Class List: Tick the vegetation classes to include in segmentation:
      • Ground
      • Tussock
      • Shrub
      • Tree
      • Sedge
    • You may select any combination of these classes (e.g., 2 out of 5).
  • After configuration, click Run New Analysis to process segmentation.

d. Bare Areas​

  • Toggle ON to identify un-vegetated regions.
  • Inputs:
    • Radius: Specifies the area around each pixel (in metres) to check for vegetation absence.
      “Radius in metres to be considered as bare”
    • Exclude Non-Vegetation Classes: Filter out irrelevant classes such as tracks or rock.
    • Input Mask: Use an existing classification mask or generate one from the current classification.

e. Erosion​

  • Toggle ON to assess erosion risk.
  • Note: Will display a warning if a DSM (Digital Surface Model) has not been generated.
  • Action:
    • Click Calculate DSM Layer to enable erosion metrics.

3. Generate Report​

  • Once configuration is complete, click Generate Report at the bottom of the Analysis panel.
  • Processing status will appear in the Reports pane.

Viewing Reports​

Accessing the Report​

  • Navigate to the Reports tab.
  • Select your report to view results.

Report Components​

SectionDescription
MetadataIncludes UAV name, classification file, projection, resolution, and capture date.
Vegetation Cover ChartBar chart showing percentage coverage for each class.
Table ViewTabular format showing coverage metrics per class and per study area.
  • Toggle between Graph and Table views.
  • Click Export to download the report data.
tip
  • Use the DSM Band for accurate elevation-based plant segmentation.
  • Adjust the radius in Bare Areas based on expected vegetation gaps.
  • Exclude non-vegetation classes in Plant Health to avoid false scoring.
  • Always calculate the DSM before enabling erosion analysis.
  • Use reports over time to monitor vegetation change or degradation.
