ទិដ្ឋភាពទូទៅ

This is the tool for attributing features as you identify them visually — clicking the parcels that belong to one owner, or the points that failed inspection, and stamping the value on all of them at once.

ការប្រើប្រាស់

  • The workflow is selection-driven. Select To Input Value picks the features on the map; Selected Feature Preview shows what is currently selected, so you can confirm before writing.
  • Value takes the value to write. Use Expression switches to expression entry instead, with Expression... opening the builder and Active expression: showing what is in force.
  • For a boolean field, True and False buttons set the value directly.
  • Set Null Value writes null. This is how a field is deliberately cleared — leaving Value blank is not equivalent, since an empty text value is not null.
  • Overwrite existing value governs what happens where the field already holds data:
    • Checked — existing values are replaced.
    • Unchecked — populated fields are left alone, so only empty ones are filled. Use this to fill gaps without disturbing already-verified data.
  • Check Selected Feature Preview before clicking Apply Value. A stray click on the map adds a feature to the selection, and the preview is where that becomes visible.
  • For writing a value to a whole layer rather than a picked set, use Add value to fields. For filling nulls from a computed strategy, use Default Value Filler.
