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
