Summary

• Scope: Plants Layer
• Level: User Goal
• Actors: App User

• Assignee: Maiia

Scenarios

• Precondition: The user is in the plants layer.

• Main success scenario:

  • The user clicks on a plant type from plant database.
  • All plantings of this plant type on the map are visually highlighted.
  • The status panel displays the number of plantings and areas of plantings which are currently highlighted.

• Alternative scenario:

  • The user clicks on a plant type not currently present on the map:
    • No existing plantings are highlighted.
    • The status panel displays the message "No plantings of this type at this date on the map."

• Error scenario:
  The user clicks on a plant type but the app is experiencing technical difficulties and is unable to highlight plantings on the map, displaying an error message.

• Postcondition:

  • Visual highlighting of plantings persists as long as user is able to plant the respective plant type.
  • Upon exit of planting mode or click on a different plant type, previously highlighted plantings become non-highlighted and if needed, plantings of another plant type become highlighted.

• Non-functional Constraints:

  • Visual feedback (e.g. outline, glow, or color overlay) should be non-intrusive and clearly distinguishable even in the presence of protagonist-antagonist relationship lines and areas.
  • Visual feedback should be distinguishable both when plantings intersect each other and when they don't.
  • Highlight must occur without noticeable delays for up to 10.000 of plantings.
