KarhutlaWatch

Satellite thermal detections, placed in geographic and temporal context across Indonesia.

Investigation question

Where and when do satellite fire detections concentrate across Indonesia?

Indonesia map of 58,099 satellite thermal-detection records for 29 September–5 October 2026. Concentrations appear in southern Kalimantan, southern Sumatra and southern Papua.

Purpose

Satellite thermal detections, placed in geographic and temporal context across Indonesia.

Personal contribution

I built the public dashboard and automated pipeline: ingesting NASA FIRMS data, assigning regions, aggregating observations, and tracking repeated activity.

QuadLake Indonesia

Original QuadLake Tableau export comparing district building-footprint counts and density across Indonesia.

Personal project

Turning fragmented building-footprint files into inspectable regional reporting data.

I built the Bronze, Silver, and Gold pipeline and CLI, with validation, spatial assignment, and reconciled reporting outputs.
