Dissolve Analysis

Merge features based on attribute values, optionally aggregating numeric fields.

Overview

Dissolve analysis merges adjacent or overlapping features that share the same attribute value, creating simplified datasets.

Inputs

Source Dataset: Dataset to dissolve
Dissolve Field: Field to dissolve on (or merge all)
Aggregation Fields (optional): Fields to aggregate with functions

Outputs

New dataset containing:

Merged geometries for each group
Aggregated attribute values
Group identifiers

Aggregation Functions

Sum: Sum of numeric values
Average: Average of numeric values
Min/Max: Minimum/maximum values
Count: Count of features

Example

{
  "source_dataset_id": 123,
  "dissolve_field": "category",
  "aggregation_fields": {
    "population": "sum",
    "area": "sum"
  }
}

Background Jobs

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

Use Cases

Administrative boundary simplification
Aggregated statistics
Data generalization
Map simplification

Notes

Adjacent features are merged
Aggregation required for numeric fields
Complex geometries may slow processing
Results depend on dissolve field values
