Core Demonstration Area Farmland Flooding Disaster Dataset
Listed in ScienceDB
This dataset contains the relevant data on flood disasters in the Chenjiadian core demonstration area of Nian'an County, Jilin Province.
Description
It is mainly used for flood disaster identification mapping, result comparison display, and sample verification. The data content consists of two parts: the 2022 flood disaster mapping data and historical drone image materials.
(1) 2022 flood disaster mapping data: Located in the "2022 Flood Disaster" directory. The core data includes NDVI raster (GeoTIFF) and the resulting flood/irrigation disaster mask (GeoTIFF) generated from NDVI, and visible light raster data is provided for spatial comparison and visual interpretation. To ensure consistency in loading and subsequent processing of GIS software, overview files (.ovr), world files (.tfw), and auxiliary metadata files (.aux.xml, .xml, etc.) are also saved.

(2) Historical drone image materials: Located in the "20210827 Downed Corn\dji" directory, it includes original drone photos (DJI_XXXX.JPG). The photos are a sequence of aerial images captured on August 27, 2021 (single image resolution 5472×3648), used to record typical phenomena in the field and provide image references for flood or downed disaster interpretation. In addition, the directory contains several JPG result images (such as "Flood Disaster.jpg", "NDVI_Flood Disaster.jpg (with enlarged image)", "Visible Light_Flood Disaster.jpg (with enlarged image)", etc.) for result display and quick browsing.
They are generally used for report mapping and result verification; if quantitative analysis is required, it is recommended to use GeoTIFF raster data as the main source.
