Map Features

This page describes the interactive features of the M-580 map application.

Layer Hierarchy

The map renders layers in a specific order to ensure smaller units are clickable:

Top (front)
├── Office Markers (points)
├── National Forests, Parks, Reservations (polygons)
├── Regional Boundaries (polygons, dashed outline)
Bottom (back)
└── Base Map Tiles

Why This Matters

Regional boundaries (like USFS Southwestern Region) are large polygons that contain many smaller National Forests. By rendering regions on the bottom with transparency, you can still click on the smaller forest units inside them.

Polygon Styling

National Forests & Parks

  • Fill: Solid color at 50% opacity
  • Outline: Solid 2px stroke matching fill color
  • Hover: Increased opacity and thicker outline
  • Selected: Orange 4px outline highlight

Regional Boundaries

  • Fill: 25% opacity (more transparent)
  • Outline: Dashed line pattern
  • Purpose: Shows administrative boundaries without obscuring contained units

Point Markers

Office locations are displayed as circular markers:

  • Size: 8px radius
  • Fill: Agency color (solid)
  • Outline: White 2px stroke
  • Tooltip: Unit name appears on hover (at zoom level 6+)

Popups

Clicking any unit displays a popup with:

┌─────────────────────────────────┐
│ Unit Name                       │  (Header - green background)
│ Agency - Type                   │
├─────────────────────────────────┤
│ Address: 123 Main St...         │  (Body)
│ Phone: (555) 123-4567           │
│                                 │
│ [Visit Website]                 │  (Link button)
└─────────────────────────────────┘
