DIST Product Suite

The land Disturbance product (DIST) maps vegetation disturbance detected when vegetation cover decreases or spectral variation is outside a historical norm from the Harmonized Landsat-8 and Sentinel-2 A/B (HLS) scenes. Two DIST products are generated within the DIST product suite: a) the DIST_ALERT product capturing vegetation disturbance at the cadence of HLS sampling and b) the DIST_ANN product capturing the confirmed changes of the DIST_ALERT products from previous calendar year. The products are designed to share the same structure, GeoTiff file format, file-naming convention, and have posting of 30 m. All products will be accessible through the Land Processes Distributed Active Archive Center (LP-DAAC).

Below we provide product specification documentation as well as the corresponding product samples conforming to the detailed specifications. Interactive guides are provided demonstrating how products can be loaded and manipulated in an open source GIS package. Interactive white papers provided through a Jupyter notebook environment outline product introductions and showcase select applications.

DIST Product Specification Document

This document describes the specifications of the OPERA Level-3 Disturbance product (DIST) product that uses Harmonized Landsat-8 and Sentinel-2A/B (HLS) as the primary image-based inputs. The data product comes in two variants according to their temporal scope, and are thus referenced by the short names DIST_ALERT (at the cadence of HLS imagery) and DIST_ANN (a summary of DIST_ALERT over the previous year).

Legacy Sample Product Example #1

The Hermit’s Peak Fire in the Santa Fe National Forest that began April 6, 2022 and is considered active, but ~98% contained as of August 3, 2022 with ~1382 km² burned. Below is a DIST-ALERT provisional product derived from a Sentinel-2A acquisition on May 28, 2022, when the fire had only been ~48% contained.

Legacy Sample Product Example #2

The McKinney Fire in the Klamath National Forest, Siskiyou County, California began on July 29, 2022 and is currently active. As of August 30, 2022, 99% is contained out of the reported ~244 km² (60,138 acres) burned area. Below is a DIST-ALERT provisional product derived from a Sentinel-2A acquisition on August 15, 2022, when the fire had only been ~95% contained.
