Erase Analysis

Remove portions of features from an input dataset that overlap with an erase dataset.

Overview

Erase analysis removes portions of input features that overlap with erase features, creating new geometries.

Inputs

  • Input Dataset: Dataset to erase from
  • Erase Dataset: Dataset to erase with

Outputs

New dataset containing:

  • Features with erased portions removed
  • Remaining geometry after erase
  • Original attributes preserved

Example

{
  "input_dataset_id": 123,
  "erase_dataset_id": 124
}

Background Jobs

This analysis runs as a background job. See Erase Analysis Worker for details.

Use Cases

  • Exclusion zone mapping
  • Feature subtraction
  • Boundary modification
  • Area calculations

Notes

  • Overlapping portions are removed
  • Non-overlapping features preserved
  • Complex geometries may slow processing
  • Results depend on overlap extent
