Overview

Tree Inspection secondary features automate BS3998 arboricultural surveys: a parent tree point generates an RPR circle and crown polygon; a parent hedge line generates a centreline and hedge-extent polygon.

ℹ️ App version: Soarvo Mobile 0.0.130+.

Tree Inspection — Parent Feature Type Setup

Point feature type with:

_secondary_feature — default !MODIFIER-HIDE;TreeInspection
_root_feature_type_name — default !MODIFIER-HIDE;{YourRootTypeName} (e.g. TreeRoot)
_crown_feature_type_name — default !MODIFIER-HIDE;{YourCrownTypeName} (e.g. TreeCrown)
StemCnt (numeric, integers)
StemDia1–StemDia6 (numeric, mm) — each with !MODIFIER-SHOWWHEN $StemCnt != null && $StemCnt>N
RootRadius (numeric) — default !CALCRPR (RPR in metres, capped at 15m)
CrownSprd (radio) — even / uneven
Uneven: NorthSprd, EastSprd, SouthSprd, WestSprd — with !MODIFIER-SHOWWHEN $CrownSprd=='uneven'
Even: EvenSprd — with !MODIFIER-SHOWWHEN $CrownSprd=='even'

💡 Tip: !CALCRPR: 1 stem = StemDia1 × 12; 2–5 stems = √(sum of squares) × 12; 6+ = average of StemDia1 and StemCnt. Cap 15 m.

Tree Inspection — Child Root Feature Type

Linear type named as in _root_feature_type_name — Soarvo draws a circle of radius RootRadius around the tree point.

Tree Inspection — Child Crown Feature Type

Area (polygon) type named as in _crown_feature_type_name — circular polygon (even) or ellipse (uneven).

💡 Tip: Match attribute names on root/crown types to auto-copy parent values (e.g. species, condition).

Hedge Inspection — Parent Feature Type Setup

Linear feature type with:

_secondary_feature — default !MODIFIER-HIDE;TreeInspection
_hedge_edge_feature_type_name — default !MODIFIER-HIDE;{YourHedgeEdgeType}
_hedge_centre_feature_type_name — default !MODIFIER-HIDE;{YourHedgeCentreType}
width (numeric, metres)
Surveyed (radio) — left, right, or centre

Surveyed: left = centreline offsets right by half width; right = offsets left; centre = no offset.

Hedge Child Feature Types

Hedge Centre (linear) — name matches _hedge_centre_feature_type_name.
Hedge Edge (polygon) — name matches _hedge_edge_feature_type_name. Buffer polygon of hedge extent.

Field Workflow

Tree: create parent point → enter StemCnt, StemDia values, CrownSprd, and spread measurements → save. Root and crown auto-generate.

Hedge: draw parent line along surveyed edge or centre → enter width and Surveyed side → save. Edge polygon and centreline auto-generate.
