Analysis Overview

Overview

Horizon's analysis tools provide forestry reporting, spatial analysis, and integration with external analytical platforms. These tools are accessible through the Report action button in the right panel.

For data management and utility tools, see the Tools Overview.

Forestry Reports

• Production Summary: Logging production statistics by region, forest, and logging unit with date-range filtering and export
• Yield Summary: Forest yield analysis with area selection, attribute filtering, individual or grouped summary modes, and CSV export
• Wildlife Habitat Clumps: Wildlife habitat retention requirements with MATHAB and EUCHAB analysis modes for conservation planning
• Canopy Analyze: Forest canopy height analysis with custom polygon or preset shape areas, real-time validation, and comprehensive height statistics

Spatial Analysis

• Area Summary: Generate area calculations using geometry intersection analysis
• Road Analysis: Road network analysis with distance calculations and route evaluation
• State Growth Routing: Route planning and turn-by-turn directions using the State Growth Tasmania road network, with support for up to 10 stops and route export
• Canopy Height Model Filter: WMS-based canopy height model layer filtering and visualisation
• Slope Classification: Terrain slope analysis against the Forest Practices Code bands, with pixel-level distribution and steep country classification
• Imagery Tool: Re-symbolise an imagery (image service) layer on the map — stretch, classified, discrete, unique value and shaded relief rendering, colour schemes, editable class breaks, and value-range filtering
• Plot Random: Random sample plot generation within polygon boundaries for field surveys
• Observer Points Editor: Generate, save, and manage observer (viewshed) points for visibility analysis with manual placement or automatic grid-based generation
• Visibility Surface Analysis: Compute how many of a saved observer set can see each cell within a drawn extent, rendered as a colour-graded visibility surface with a legend (embedded in the Observer Points Editor)
• Line of Sight: Calculate the ground area visible from a single observer (nest) point using a digital elevation model, with adjustable observer height, radius, and detail
• Find Nearest Neighbour: Property proximity search by Provcoupe, Operation, Asset, or Custom Polygon with configurable buffer distance
• AI Segmentation: Trace object outlines from aerial or satellite imagery with an AI segmentation model — click objects to capture their polygons, then export or save them as My Layers
• VR Calculator Alpha: Variable Retention influence statistics for forestry coupes — what percentage of the felled area falls within the influence zone of retained trees, from LiDAR or user-entered tree heights

Retired Tools

• Horizon Analyst — removed in v2.24.0. The companion application is no longer integrated with Horizon and is not listed in the Report Tools dropdown; the page is kept for reference
