Account-ready data: ecosystem extent in the Flinders, Norman and Gilbert river catchments. A data collection from the Regional Ecosystem Accounting Pilot projects

This is a collection of account-ready data of ecosystem extent in the Flinders, Norman and Gilbert (FNG) river catchments. The spatial extent of ecosystems was derived from conceptual state and transition models, developed by experts, for nine ecosystem types in the FNG (noting that other ecosystem types were also found in the FNG but state and transition models were not developed for these). The state and transition models were constructed using methods underpinned by the Australian Ecosystem Models (AusEcoModels) Framework and ecosystem states were then mapped each year from 1988 to 2020 using remotely sensed imagery and maps. These products were interpreted using decision rules informed by ecosystem attributes for each ecosystem state that were provided by experts. This collection includes the spatial extent of ecosystem types and states, and SEEA EA ecosystem functional groups across the FNG river catchments each year from 1988 to 2020 as GeoTIFF files, as well as the python scripts used to produce the extent maps.

本数据集收录弗林德斯河（Flinders）、诺曼河（Norman）与吉尔伯特河（Gilbert）组成的FNG河流流域内可用于生态系统核算的生态系统空间范围数据。该流域内生态系统的空间范围源自专家针对FNG流域内9种生态系统类型开发的概念性状态与转换模型，需说明的是，FNG流域内还存在其他生态系统类型，但尚未为其开发对应的状态与转换模型。此类状态与转换模型依托澳大利亚生态系统模型（AusEcoModels）框架确立的方法构建，研究团队随后于1988年至2020年期间，每年利用遥感影像与地图对生态系统状态进行制图。上述制图成果通过专家提供的、针对各生态系统状态的生态系统属性所确立的决策规则完成解译。本数据集包含1988年至2020年每年的FNG河流流域内生态系统类型、生态系统状态以及SEEA EA生态系统功能群的空间范围数据，数据格式为GeoTIFF文件，同时附带用于生成范围图的Python脚本。
