System use case specification view calculated phytosociological parameters by species - ESG-Project/documentation GitHub Wiki


Identification	UC34
Use case	View Calculated Phytosociological Parameters by Species
Actors	User
Stakeholders and interests	Forest Inventory Analyst: Needs detailed per-species parameters for in-depth ecological analysis and technical reporting.
Pre-conditions	The user is in a Phytosociological Analysis with specimen data entered. Phytosociological calculations have been processed by the system.
Minimum guarantees	System correctly applies standard formulas for all calculations.
Success guarantees	A comprehensive table of calculated phytosociological parameters per species is displayed, with sorting and customization options.

Main Success Scenario

User Action	System Response
1. This use case begins when the user accesses the "Phytosociological Parameters" section (or "General" tab) within the Phytosociological Analysis.	2. The system automatically calculates all required phytosociological parameters based on the specimen data for the analysis. Data generated and displayed per species includes: SPECIES, FAMILY, DENSITY, RELATIVE DENSITY (%), DOMINANCE, RELATIVE DOMINANCE (%), FREQUENCY, RELATIVE FREQUENCY (%), IMPORTANCE VALUE (VI), COVER VALUE (VC), ABSOLUTE IVI, INDIVIDUAL VOLUME, TOTAL VOLUME PER SPECIES, Average DBH per species, and Average Height per species.
	3. The system displays these parameters in an interactive table or relevant graphs.
4. The user can sort the table by any column and customize which columns are displayed.	5. The system updates the table display according to user preferences.

Displayed Parameters: Table must include Density, Dominance, Frequency (absolute & relative), VI, VC, IVI, Individual/Total Volume, average DBH/Height per species.
Table Features: Sorting by column and column customization are required.
Calculation Basis: Calculations must adhere to standard phytosociological formulas.
