Import DCE Layer

The Import DCE Layer tool allows you to import features from an existing file or map layer into a Data Capture Event (DCE) layer.

This tool facilitates the migration of existing data into your QRiS project structure. It handles geometry import, attribute mapping, and optional spatial clipping.

Parameters

Input Selection

  • Input Feature Class / Map Layer: Displays the source dataset selected for import.
  • Data Capture Event: Displays the QRiS event associated with the target layer.
  • Target Layer: The destination layer in the QRiS project where features will be added.

Clip to AOI

  • Clip to AOI: Select an Area of Interest (AOI) to clip the imported features, or choose "None" to retain the full dataset extent.

Fields

You can choose to Import Fields or Ignore Fields using the radio buttons.

When Import Fields is selected, a table displays the input fields and available mapping options:

  • Input Field: The name of the field in the source dataset.
  • Data Type: The data type of the source field.
  • Retain Values: Check this to store the original attribute values within the metadata column of the QRiS database. This preserves source data even if it doesn't map to a standard QRiS field.
  • Transfer Values: Use the "Assign..." button or the checkbox to map unique values from the input field to standard values in the destination schema. This is useful for transposing the existing attributes into the standardized attributes of the DCE layer.
  • Copy Values: Use the checkbox and dropdown to copy values from the input field directly into a compatible QRiS target field.

Usage

  1. Verify Inputs: Ensure the correct Input Feature Class and Target Layer are shown.
  2. Set Clipping: Choose an AOI to clip to, if necessary.
  3. Map Attributes:
    • Review the field list.
    • Decide which fields to retain as metadata.
    • Map specific values or copy fields to target columns as needed.
  4. Run: Click OK to execute the import.

The tool will process the features, handling any necessary geometry conversions (e.g., exploding multi-part geometries) and report the number of features successfully imported.
